Sometimes the hole is slightly off-center. The spanner [53] or Snake-Eyes trademarked [54] screw drive uses two round holes opposite each other and is designed to prevent tampering. Other informal names include pig nose , drilled head or twin hole. The driving tool is called a "spanner driver" or "spanner screwdriver" [56] in the US, and a "pin spanner" in the UK.

The knife and gun manufacturer Microtech uses a variation of this with 3 round holes arranged in a triangle shape. The camera company Leica Camera has used versions of this on rewind knobs and other levers on their rangefinder cameras. The spline screw drive has twelve splines in the fastener and tool. Spline drives are sized via numbers. Its primary advantage is its ability to resist cam out , so it is used in high-torque applications, such as tamper-proof lug nuts , cylinder head bolts, and other engine bolts.

Torq-set is a cruciform screw drive used in torque-sensitive applications. The Torq-set head is similar in appearance to a Phillips drive in that it has a cross with 4 arms. In Torq-set however, the lines are offset from each other, so they do not align to form intersecting slots across the top of the head. Because of this, a regular Phillips or flat-blade screwdriver will not fit the head. It is used in military and aerospace applications.

The ribbed version is also known as ACR Torq-set. The TA is a type of screw drive that uses a triangle-shaped recess in the screw head. Note that the sides of the triangle are straight, which differs from TP3 fasteners. They can also be found in devices such as vacuum cleaners, fan heaters, elevators , camping stoves, golf clubs, Breville kettles and Master Locks, among others, to help restrict access to the device internals.

They can readily be driven with hex keys. TP3 sometimes referred to as tri-lobe or tri-lobular is a type of screw drive that uses a Reuleaux Triangle -shaped recess in the screw head, so that it cannot be driven by a flat-blade screwdriver.

The tri-point or Y-type security screw head is similar to the Phillips screw head, but it has three points rather than four. Tri-groove or T-groove is a design for a security screw with a flat-topped conical head and three short radial slots that do not join in the center. The tri-wing , also known as triangular slotted , is a screw with three slotted "wings" and a small triangular hole in the center.

Unlike the "tri-point" fastener, the slots are offset, and do not intersect the center of the fastener. A version with left-hand threads is called an Opsit screw, where unscrewing can be done by turning the screwdriver clockwise, which is the opposite of tri-wing and regular screws. The design was adopted by some parts of the aerospace industry, led by Lockheed in the early s on the L , but met with mixed results due to complaints of insert damage during installation.

British Aerospace and Airbus are also users of this fastener. In the present day it is usually seen on electronics equipment. There are various other ways to categorize screw drives. One way is by shape of the fastener screw drive:.

A cross-head screw with a two-step driver design, with the blade diameter stepping up at a distance from the point. It looks like a Phillips screw, but is designed not to cam out and will therefore be damaged by a Phillips screwdriver if it is too tight.

Heads are usually identifiable by a single dot or an "X" to one side of the cross slot. The Mortorq drive, developed by the Phillips Screw Company, is a format used in automotive and aerospace applications.

It is designed to be a lightweight, low-profile and high-strength drive, with full contact over the entire recess wing, reducing risk of stripping. Pozidriv drive bits are often designated by the letters "PZ" plus a size code of 0, 1, 2, 3, 4 or 5 by order of increasing size ; [6] the numerical bit size codes do not necessarily correspond to nominal screw size numbers.

Attempting to use a Phillips screwdriver bit is likely to cause damage because the design difference between them is fairly significant even though at first glance they appear to be very similar. The Phillips driver has four simple slots cut into it, whereas in the Pozidriv each slot is the result of two machining processes at right angles.

The result of this is that the arms of the cross are parallel-sided with the Pozidriv, and tapered with the Phillips. The chief disadvantage of Pozidriv screws is that they are visually quite similar to Phillips; thus many people are unaware of the difference or do not own the correct drivers for them, and often use an incorrect screwdriver.

This results in difficulty with removing the screw and damage to the recess or driver, often rendering any subsequent use of a correct screwdriver unsatisfactory.

Phillips screwdrivers will loosely fit in and turn Pozidriv screws, but will cam out if enough torque is applied, potentially damaging the screw head or driver. The Supadriv sometimes spelled incorrectly as "Supadrive" screw drive is very similar in function and appearance to Pozidriv— indeed, the two are often thought [ by whom?

The description of the Pozidriv head applies also to Supadriv. While each has its own driver, [26] the same screwdriver heads may be used for both types without damage; for most purposes it is unnecessary to distinguish between the two drives.

Pozidriv and Supadriv screws are slightly different in detail; the later Supadriv allows a small angular offset between the screw and the screwdriver, while Pozidriv has to be directly in line.

In detail, the Supadriv screwhead is similar to Pozidriv but has only two identification ticks, and the secondary blades are larger. Drive blades are about equal thickness. The main practical difference is in driving screws into vertical surfaces: that close to a near vertical surface to drive the screws into the drivers, Supadriv has superior bite, making screwdriving more efficient, with less cam out.

Both the tool and the socket have a slight taper. Originally to make the manufacture of the screws practical using cold forming of the heads, [10] : 79—81 this taper provides two other advantages which have served to popularize the drive: it makes inserting the tool easier, and tends to help keep the screw on the tool tip without the user needing to hold it there.

Robertson screws are commonplace in Canada , though they have been used elsewhere [10] : 85—86 and have become much more common in other countries in recent decades.

As patents expired and awareness of their advantages spread, Robertson fasteners have become popular in woodworking and in general construction. Robertson screwdrivers are easy to use one-handed, because the tapered socket tends to retain the screw, even if it is shaken. The socket-headed Robertson screws are self-centering, reduce cam out , stop a power tool when set, and can be removed if painted over or old and rusty. The internal-wrenching square socket drive for screws as well as the corresponding triangular socket drive was conceived several decades before the Canadian P.

Robertson invented the Robertson screw and screwdriver in and received patents in Canada and U. Patent 1,, An earlier patent covering both square-socket- and triangle-socket -drive wood screws, U. However, as with other clever drive types conceived and patented in the s through s, it was not manufactured widely if at all during its patent lifespan due to the difficulty and expense of doing so at the time. Today, cold forming via stamping in a die is still the common method used for most screws sold, although rotary broaching is also common now.

Linear broaching to cut corners into a drilled hole similar to the action of a mortising machine for woodworking has also been used less commonly over the decades. Robertson had licensed the screw design to a maker in England, but the party that he was dealing with intentionally drove the licensee company into bankruptcy and purchased the rights at a reduced price from the trustee, thus circumventing the original agreement.

When Henry Ford tried out the Robertson screws, he found that they saved considerable time in Model T production, but when Robertson refused to license the screw design, Ford realized that the supply of screws would not be guaranteed and chose to limit their use in production to Ford's Canadian division. The restriction of licensing of Robertson's internal-wrenching square may have sped the development of the internal-wrenching hexagon , although documentation of this is limited.

The design is similar to a square drive Robertson , but which can be engaged at more frequent angles by the driver bit. Common sizes are 6, 8, 10, and 12 mm. The name derives from overlaying three equal squares to form such a pattern with 12 right-angled protrusions a pointed star. The design is similar to that of the double-square —in both cases, the idea being that it resembles a square Robertson but can be engaged at more frequent angles by the driver bit.

These screws can be driven with standard Robertson bits. In practice, drivers for the fasteners may or may not interchange, but should be examined carefully for proper fit before application of force. A hex key should not be used where a key of square cross-section is the correct fit.

Triple-square drive fasteners have been used in high-torque applications, such as cylinder head bolts and drive train components. The fasteners involved have heads that are hardened and tempered to withstand the driving torque without destroying the star points. The hex socket screw drive has a hexagonal recess and may be driven by a hex wrench , also known as an Allen wrench , Allen key , hex key , or inbus as well as by a hex screwdriver also known as a hex driver or bit.

Tamper-resistant versions with a pin in the recess are available. In many countries it is commonly but incorrectly called "i m bus". Double hex is a screw drive with a socket shaped as two coaxial offset hex recesses; it can be driven by standard hex key tools.

The shape resembles triple square and spline screw drives, but they are incompatible. The radial "height" of each arris is reduced, compared to a six-point, although their number is doubled. They are potentially capable of allowing more torque than a six-point, but greater demands are placed on the metallurgy of the heads and the tools used, to avoid rounding off and slippage.

It was designed to permit increased torque transfer from the driver to the bit compared to other drive systems. The drive was developed in [38] by Camcar Textron. A tamper-resistant Security Torx head has a small pin inside the recess. Owing to its six-fold symmetry, a Torx driver can also be used as an improvised substitute for a hex driver, although careful sizing is critical to prevent stripping the socket.

Torx Plus is an improved version of Torx that extends tool life even further and permits greater torque transfer compared to Torx.

The Tamper-resistant variant, often called Torx Plus Security , is a five-lobed variant, with a center post. These "5-star" Torx configurations are commonly encountered in prisons , public facilities and public schools, but can also be found in some electronic devices. Torx TTAP is a version of Torx that reduces wobbling between the fastener and the tool, and is backward compatible with standard hexalobular tools.

An External Torx version exists, where the screw head has the shape of a Torx screwdriver bit, and a Torx socket is used to drive it. Some screws have heads designed to accommodate more than one kind of driver, sometimes referred to as combo-head or combi-head. The most common of these is a combination of a slotted and Phillips head , often used in attaching knobs to furniture drawer fronts.

Because of its prevalence, there are now drivers made specifically for this kind of screw head. Other combinations are a Phillips and Robertson, a Robertson and a slotted, a Torx and a slotted and a triple-drive screw that can take a slotted, Phillips or a Robertson.

Their rise to popular use has been in spite of the fact that neither a flat screwdriver or Pozidriv screwdriver are fully successful in driving these screws to the required torque. Some screwdriver manufacturers offer matching screwdrivers and call them "contractor screwdrivers", although the original concept of not needing to search for a particular driver being defeated as a contractor screwdriver is useless for non-combination heads.

While a standard Phillips or Robertson tool can be used, there is also a dedicated tool for it that increases the surface area between the tool and the fastener so it can handle more torque.
