Description

Engineered for durability and precise clamping, this Socket Head Cap Screw in Alloy Steel with a Thermal Black Oxide finish delivers reliable performance in tight spaces. The 5-40 thread size and 1/2 inch length make it ideal for compact assemblies where strength and space are critical.

Key Features

  • Head type: Socket head cap screw (Allen drive) for high-torque applications in confined areas
  • Material: Alloy steel for high strength and durability
  • Finish: Thermal black oxide provides a dark, low-glare appearance with mild corrosion resistance and improved lubricity
  • Thread size: 5-40; Length: 1/2 inch
  • Applications: Ideal for machinery, automotive components, electronics enclosures, and general industrial hardware

Applications & Benefits

Use this screw in assemblies that demand secure fastening and lasting performance in compact spaces. The socket head design enables high torque fitting with minimal head protrusion, while the alloy steel body offers reliable strength and fatigue resistance. The black oxide finish reduces glare and blends with dark components, and it works well with compatible lubricants to enhance installation and disassembly.

Care & Installation Tips

  • Lubricate threads to reduce friction and prevent galling during installation
  • Avoid overtightening to protect threads and maintain clamping force
  • Store in a dry environment to preserve the finish and longevity
