1/4-28 x 3 1/2 1960 Series Alloy Steel Socket Head Cap Screw with Nylon Insert combines alloy steel construction, an internal hex drive, and a nylon locking insert in one cataloged fastener. The insert adds prevailing-torque resistance through localized nylon contact, so the fastener can be considered where service conditions call for added loosening resistance.

The 1/4-28 x 3 1/2 size is often reviewed for industrial equipment, material-handling systems, and machine frames when the bill of materials calls for an alloy steel cap screw with a nylon insert. Review thread size, length, mating material, available drive access, and insert location before release to production or maintenance use.

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