Description

Hex Head Cap Screws Grade 5 Steel Plain Fine Thread 1/2-20 x 3 are engineered for high-strength fastening in machinery, automotive, and fabrication projects. These screws feature a robust Grade 5 steel body with a plain finish, providing dependable performance in dry or non-corrosive environments.

Key specifications

  • Head style: Hex head cap screw
  • Material: Grade 5 steel
  • Finish: Plain (uncoated)
  • Thread: 1/2-20 UNF (fine thread)
  • Length: 3 inches

Ideal for through-hole and blind-hole assemblies that demand substantial strength and reliability. The plain finish keeps compatibility broad across non-coated applications, while the fine thread provides better engagement in precision-fit joints.
