This 1/2-20 x 1 3/4 Alloy Steel Socket Head Cap Screw with Nylon Insert belongs to the Cold Headers 1960 Series for socket head cap screws with prevailing-torque nylon inserts. The prevailing-torque insert is useful when a drawing specifies a socket head cap screw with a nylon locking element rather than a standard socket screw.

The 1/2-20 x 1 3/4 size is often reviewed for driven equipment, actuator mounts, and controlled motion assemblies when the bill of materials calls for an alloy steel cap screw with a nylon insert. Engineers should confirm that the selected size, nylon insert position, and mating threads suit the assembly before substituting from a standard socket cap screw.

Cold Headers has supplied specialty socket fasteners since 1962 and supports exact-size sourcing for difficult-to-find socket products.
