Description

Durable and versatile, these Hex Head Cap Screws are crafted from Grade 2 steel with a plain finish. The fasteners measure 5/16-18 x 4 1/2 inches (PT) and are designed for general-purpose applications where reliable clamping is required.

  • Material: Grade 2 steel
  • Finish: Plain (uncoated)
  • Head type: Hex head cap screw
  • Thread size: 5/16-18 UNC
  • Length: 4-1/2 in
  • Drive: Hex (requires standard hex socket or wrench)

These hex head cap screws offer solid strength for light to moderate duty tasks and are a cost-effective choice for a wide range of projects. They pair with nuts or tapped holes threaded for 5/16-18 and can be installed with a standard hex wrench or socket for quick, secure fastening.

Common applications include furniture assembly, shelving, basic machinery mounting, general construction hardware, and other DIY or light industrial projects. Note: plain Grade 2 steel provides basic performance and is not a corrosion-protected finish; for outdoor or moisture-prone environments, consider coated or different alloy options.
