These machine screws are designed to work with standard 5/16-18 nuts or tapped holes, providing a reliable fit for a wide range of assemblies. The wide truss head helps distribute load and minimize pull-through, making them suitable for softer metals and thin panels where a secure seating is essential.

- Pre-drill pilot holes when working with harder materials to reduce stress and prevent splitting
- Avoid over-tightening to protect threads and maintain fastener integrity
