The VALUE COLLECTION A997502 is a hex socket cap screw intended for fastening applications that demand corrosion resistance and consistent thread engagement. Built from 18-8 stainless steel, this screw features a 5/16-18 UNC thread size and a 3-1/2 inch length under head. The 1/4-inch hex drive accepts a standard Allen wrench or hex bit driver, allowing controlled torque application in tight clearances. Supplied in a package of 10, this fastener suits maintenance, fabrication, and mechanical assembly tasks across trade and industrial settings. Installers working in HVAC, plumbing, and general mechanical environments will find the stainless construction suitable for both indoor and outdoor use.
This screw is appropriate for general-purpose fastening in residential, commercial, and light industrial applications. The 5/16-18 UNC coarse thread offers reliable thread engagement in standard tapped holes and through-bolt assemblies. The hex socket drive is well suited for recessed mounting locations where a standard hex head wrench cannot be used. Applications include equipment panels, brackets, housings, and structural assemblies that require a flush or low-profile cap head fastener.
Designed as a general-purpose hex socket cap screw for standard 5/16-18 UNC tapped holes in mechanical and structural assemblies.
Installation requires a 1/4-inch hex key or hex bit driver. Ensure the mating hole is properly tapped to 5/16-18 UNC specification before driving the screw. De-energize and lock out any equipment before accessing fastener locations on live machinery. Avoid over-torquing stainless steel fasteners, as 18-8 stainless is susceptible to galling if driven too aggressively without lubrication.
