Description

Hex Head Cap Screws Grade 5 Steel Plain 5/16-18 x 1-1/4 are high-strength machine screws designed for secure fastening in a wide range of applications. The plain steel construction delivers dependable performance in non-coated environments where a simple, versatile fastener is required.

  • Head type: Hex head for easy driving with standard wrenches or sockets.
  • Material and finish: Grade 5 steel with a plain (uncoated) finish for durable daily use.
  • Thread size and length: 5/16-18 UNC thread, 1-1/4 inch long.
  • Usage: Ideal for machinery, equipment, automotive assemblies, and general construction projects when a strong, reliable connection is needed.
  • Compatibility: Designed to be paired with compatible nuts or tapped holes that match the 5/16-18 UNC thread.

When installing, ensure correct thread engagement and choose the appropriate length to avoid over-penetration. Note that plain steel is not a corrosion-resistant finish, so consider coating or environmental protection for outdoor or exposure-prone applications.
