FEATURES

Socket head cap screws are high tensile strength precision fasteners that have a small cylindrical head with a hexagon socket and external machine screw threads. They are used with bearing caps, machine assemblies, punch press tooling, shaft collars and other applications. Except for four fractional sizes—1/4, 5/16, 7/16 and 9/16"—their maximum head diameter is the same as the maximum width across flats of like-sized hex head cap screws. Because they are internally wrenched, heads can be recessed in counterbored holes or protrude above the mating surface and be closely spaced. Their high strength allows for fewer screws or smaller size screws to be used, which can reduce assembly size and weight while delivering holding power at the lowest cost per pound of fasteners. There is another potential cost savings: fewer screws means fewer drilled and tapped holes are needed. Officially known as hexagon socket head cap screws , they are usually mated with internally threaded (tapped) holes rather than nuts. Other head styles are listed below
