This 5-40 x 1 1/2 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 insert adds prevailing-torque resistance through localized nylon contact, so the fastener can be considered where service conditions call for added loosening resistance.
In tooling, inspection fixtures, and precision assemblies, the internal hex drive allows compact tool access while the alloy steel body keeps the product aligned with drawings that specify this material. For replacement work, matching the thread, length, pellet diameter, and pellet location helps align the part with service records and existing hardware.
Cold Headers provides catalog depth for specialty socket fasteners and helps purchasers identify the correct alloy steel nylon insert configuration.
