For drawings calling out a locking button head socket screw, the 5/16-24 x 2 Alloy Steel Button Head Socket Cap Screw with Nylon Insert keeps exact thread and length identification clear. The nylon insert helps resist loosening through friction at the mating threads, providing prevailing torque without requiring a separate locking component.
The button head profile offers reduced head projection, a smooth exposed appearance, and a broad bearing surface compared with a standard cylindrical socket head. In automation systems, robotic fixtures, and inspection tooling, 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.
Since 1962, Cold Headers has helped industrial buyers locate specialty socket screws, replacement sizes, and unusual catalog configurations.
