Value Collection 209050B Hex Head Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 209050B is a hex head cap screw designed for general-purpose fastening in industrial, mechanical, and trade applications. It features a 5/16-18 UNC thread with a 1-3/4 inch length under head, providing a reliable fastening solution where corrosion resistance is a priority. Constructed from 18-8 stainless steel, this screw offers solid resistance to rust and oxidation, making it well suited for environments exposed to moisture or mild chemical contact. The 1/2 inch hex drive size accommodates standard hex wrenches and sockets. Licensed trades including HVAC technicians, plumbers, and electricians routinely use fasteners of this type when assembling brackets, equipment mounts, and panel hardware.

This screw is appropriate for residential and light commercial installations where an inch-system UNC thread fastener is required. Common applications include equipment mounting, structural brackets, access panel hardware, pipe hanger assemblies, and general mechanical fabrication. The 18-8 stainless steel grade suits indoor and outdoor installations where mild corrosion exposure is anticipated. This fastener is sold individually per package, with a minimum order quantity of 100 pieces.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, electricians, or mechanical contractors using a 1/2 inch wrench or socket. Power down or de-energize any equipment before fastening hardware to panels or electrical enclosures. Do not overtighten stainless steel fasteners, as galling can occur; applying an appropriate anti-seize compound to the threads is a common field practice. Ensure the mating material and thread specification match before installation.
