3/8-24 x 1/2 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 insert provides a prevailing-torque feature while preserving the compact top-side tool access expected from an internal hex button head screw.
The button head profile offers reduced head projection, a smooth exposed appearance, and a broad bearing surface compared with a standard cylindrical socket head. Typical uses include packaging machinery, conveyor equipment, and production cells, where a precise socket fastener with a low rounded head can support compact machinery layouts. Selection should account for joint geometry, thread engagement, installation access, head clearance, and the desired level of prevailing torque.
Cold Headers has supplied specialty socket fasteners since 1962 and supports exact-size sourcing for difficult-to-find socket products. 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.
