3/8-24 x 1 Alloy Steel Button Head Socket Cap Screw with Nylon Insert is a socket-driven fastener for assemblies that need a rounded low-profile head plus a built-in prevailing-torque feature. The nylon insert helps resist loosening through friction at the mating threads, providing prevailing torque without requiring a separate locking component.
Button head geometry is useful when clearance, appearance, and lower head height matter more than using a standard socket head cap screw profile. In machine guards, equipment covers, and service panels, the internal hex socket drive allows tool access from above while the nylon insert adds frictional resistance at the threads. For replacement applications, matching the exact diameter and length helps align the part with drawings, service records, and existing hardware.
Cold Headers supports distributors, OEM sourcing teams, and maintenance operations that need uncommon lengths or precise button head nylon insert configurations. For adjacent selections, buyers often compare standard Alloy Steel Button Head Socket Cap Screws, Alloy Steel Socket Head Cap Screws, and Alloy Steel Flat Head Socket Cap Screws when checking head style, material, locking feature, thread size, or nearby lengths.
