Value Collection 207494C Hex Head Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 207494C is a hex head cap screw designed for structural fastening in industrial, mechanical, and trade applications. It features a 1/2-13 thread size with a Unified National Coarse (UNC) thread standard and a length under head of 1.75 inches. The fastener is manufactured from 18-8 stainless steel, providing reliable corrosion resistance in wet, outdoor, and chemically exposed environments. The 3/4-inch hex drive accommodates standard wrenches and sockets. This screw is a staple fastener for plumbers, HVAC technicians, electricians, and general mechanical contractors working on equipment mounting, pipe supports, and panel assemblies.

This hex head cap screw is suited for both light commercial and residential trade applications. It is commonly used when fastening equipment frames, mounting brackets, strut channel assemblies, and mechanical supports where corrosion resistance is a requirement. The 18-8 stainless steel grade performs well in moderate chemical and moisture exposure, making it appropriate for mechanical rooms, rooftop installations, and outdoor equipment pads. These screws are sold individually per package, with a minimum order quantity of 50 pieces.

Installation Notes

Installation is typically performed by licensed mechanical, plumbing, or electrical tradespeople using a standard 3/4-inch wrench or socket. Always de-energize and isolate equipment before fastening near electrical components. Follow applicable torque guidelines from the equipment manufacturer and adhere to relevant code requirements such as NEC or IPC where structural fastening is involved. Do not over-torque stainless steel fasteners, as galling can occur without proper lubrication or anti-seize compound.
