Description

Upgrade your toolkit with our Hex Head Cap Screws Grade 2 Steel Zinc Plated, sized 5/16-18 x 5. Designed for dependable, general-purpose fastening, these hex head cap screws combine solid strength with corrosion resistance to handle everyday worksite tasks and shop projects.

Key Features

  • Material: Grade 2 steel
  • Finish: Zinc plated for corrosion resistance
  • Head Type: Hex head for easy driving with a standard wrench or socket
  • Thread: Coarse 5/16-18 UNC
  • Size: 5/16 diameter, 18 threads per inch
  • Length: 5 inches

Applications include general metal-to-metal, wood-to-metal, and machinery assemblies in automotive, industrial, and DIY projects. Because this is Grade 2 steel, it offers dependable strength for everyday tasks but is not intended for high-load structural connections. The zinc plating helps resist corrosion in moderate environments, making these screws a versatile choice for workshops and fabrication shops.

Installation tips

  • Compatibility: Use with compatible nuts and tapped holes; ensure the thread engagement matches the thickness of the joined components.
  • Lubrication: Lightly lubricate threads to reduce galling and ease installation.
  • Torque: Apply appropriate torque for the materials and fastener size to prevent over-tightening.
