Description

Socket Head Cap Screws in Alloy Steel with a Thermal Black Oxide finish. Size: 5/16-18 x 3/8, ideal for precise, high-strength assemblies where a low-profile, secure fastener is required.

Product Features

  • Material: Alloy steel for enhanced strength and durability.
  • Finish: Thermal black oxide delivers a low-gloss appearance and improves resistance to wear and corrosion in typical environments.
  • Size and Thread: 5/16-18 thread with a length of 3/8 inch.
  • Head Style: Socket head cap screw designed for a clean, flush fit with a hex drive for easy installation and removal.
  • Applications: Suitable for machinery, automotive assemblies, and general purpose fastening where strong clamping in confined spaces is needed.

Why Choose These Screws?

Engineered for high clamp loads in tight spaces, these socket head cap screws provide reliable performance under demanding conditions. The alloy steel construction ensures strength, while the thermal black oxide finish reduces glare and offers moderate protection against corrosion in non-extreme environments.
