The VALUE COLLECTION 209010 is a 5/8-11 hex head cap screw measuring 4 inches under the head, manufactured from 18-8 stainless steel. The 18-8 alloy designation indicates a composition of approximately 18% chromium and 8% nickel, providing solid corrosion resistance suitable for general industrial, mechanical, and trade applications. The 5/8-11 thread designation follows the Unified National Coarse (UNC) standard, making it a widely used fastener size for structural and mechanical assemblies. The 15/16-inch hex drive accommodates standard socket and wrench tooling. This screw is installed by maintenance technicians, pipefitters, millwrights, and general tradespeople working across HVAC, plumbing, and mechanical systems.
This fastener is suited for indoor and outdoor mechanical assemblies where moderate corrosion resistance is required. The UNC thread profile is compatible with standard 5/8-11 tapped holes and nuts commonly found in equipment frames, pipe supports, duct hangers, pump bases, and structural bracketing in both residential and light commercial settings. The 18-8 stainless construction makes it appropriate for damp or humid environments where carbon steel fasteners would be prone to rust.
Designed for use in any application requiring a 5/8-11 UNC hex head cap screw with a 4-inch length under head in 18-8 stainless steel. Fits standard 5/8-11 threaded holes and nuts per UNC specifications.
Install using a 15/16-inch socket or open-end wrench. De-energize or shut down any equipment before fastener service. Apply anti-seize compound when joining stainless fasteners to stainless or aluminum mating surfaces to prevent galling. Follow applicable mechanical and structural codes for torque and fastener spacing requirements in your jurisdiction.
