Item #: 80956717Brand: Value CollectionModel #: Features and Benefits Socket cap head types have large cylindrical heads with recessed hex-shaped drives. They are ideal for applications where limited clearance would not allow the use of wrenches and sockets. Torx Plus fasteners require Torx Plus drivers to achieve full torque. Standard Torx drivers can also be used to tighten and loosen fasteners but will not achieve the same torque. Alloy steel is the strongest of all steel types. It has high tensile strength and offers excellent resistance to wear, fatigue and galling.
