Drive Types
Common screw drive prone to cam-out (stripping) when high torque is applied.
Similar to Phillips, but features a sharp tip and larger angle in the V shape. Improved torque with reduced risk for cam
out (stripping).Improved version of the Phillips drive intended to handle more torque.
Driven by at screw driver often used in wood working applications. Prone to cam-out (stripping) when high torque is applied.
Versatile drive that can be used with slotted or Phillips screw drivers.
Resistant to cam-out when high torque is applied. Tapered socket retains screw even if shaken.
Designed as a combination Phillips and Robertson drives, this drive handles increased torque than its individual
counter parts.
Combination Roberstson and slotted drive. Driven by either a at screw driver or Robertson driver. Increased
resistance to cam out (stripping) during installation.
Combination drive that combines two of the most popular drives in one. Prone to cam-out when high torque is applied. For
use with wrench or Phillips driver.
Improved version of the Phillips drive intended to handle more torque.
Allows a small angular oset between the screw and the screwdriver. Has superior bite, with less risk of cam out (stripping).
Compact and easy to drive.
Designed for reduced risk of cam out (stripping), higher torque, and o-angle drivability.
Lightweight, low-prole and high strength drive, with full contact over the recess ring reducing the risk of cam out (stripping)
Spline shaped with rounded ends. This drive resists camming out and is primarily used in high-torque applications.
Possesses 8 points of contact with bit making it ideal for projects requiring high installation torque.
Features square shaped lobes that allow for higher torque and minimize wear.
Can be installed and removed with a 12 point socket. Features increased torque ability. Used in the automotive industry.
Features 12 equally space tips and is often used in high-torque applications. Can be removed with Standard Robertson bits.
Drive that uses a triangle-shaped recess in the screw head for better tamper resistance. Used in children’s toys, vacuum
cleaners, fan heaters, and elevators.
Prevents unauthorized tampering with the screws. This drive has a hole in the bit tip; its counterpart in the screw head ts into
this hole, thus ensuring that only the matching assembly tool can be inserted into the screw head.
Similar to the Torx/Star, this drive has a hole located in the tip and the screw head that has a small pin that prevents
unauthorized tampering with the screws.
A winged security prole consisting of three edges. Primarily used in household appliances and in the aerospace industry.
A security prole drive consisting of four edges that are shifted asymmetrically to the centre.
The primary advantage of this prole is the surface of the screw head, which is broken only by the two small rectangular pins
and is otherwise solid. It prevents over-tightening of the screw. Not suitable for transmitting high torque.
Tamper resistant drive designed to only be turned in one direction. Cam out will occur when even minimal torque is applied
in the direction to unscrew it. A special removal tool (a one-way screw extractor) must be used.
Features twelve splines. Used in high torque applications as this design resists cam out (strip out). Often used in applications
as tamper-proof lug nuts, cylinder head bolts, and other engine bolts.
Drive with a socket shaped as two oset hexes. Standard hex keys can be used with these sockets. Capable of allowing more
torque than a six-point.
Designed to have almost all of the turning force applied at right angles to the fastener spline face, thus reducing the possibility
of cam out (stripping). Often used in softer, non-ferrous metals.
A ve-pointed tamper-resistant system. Often found in newer electronic applications.
Designed for better tamper resistance, the torx external drive featrues a screw head in the shape of a torx screwdriver bit.
Also known as standard clutch, these drives are designed to for tamper resistance. Common in automobiles, trucks and buses.
Recommended for applications requiring frequent removal that do not require friction hold.
