The VALUE COLLECTION R57001247 is a hex head cap screw designed for general mechanical and structural fastening applications. It features a 1/2-13 UNC thread size and a 6.5 inch length under the head, with partial threading along the shank. Constructed from 18-8 stainless steel and left uncoated, this fastener resists corrosion in wet, chemical, or outdoor environments. It is suitable for use in plumbing infrastructure, HVAC structural assemblies, equipment mounting, and industrial fabrication where stainless fasteners are specified. Licensed trades and maintenance professionals rely on this screw type when stainless steel is required by specification or site conditions.
This screw is applicable in residential and commercial mechanical installations where UNC-threaded stainless fasteners are called out on drawings or required by corrosion-resistance standards. The partially threaded shank provides a bearing surface that helps align mating components before full engagement. Typical uses include equipment bases, pipe hangers, access panels, and structural connections in corrosive or high-humidity environments. Sold individually, with a minimum order quantity of 5 units.
Designed as a standard inch-series hex head cap screw compatible with any 1/2-13 UNC tapped hole or hex nut in mechanical, plumbing, HVAC, and industrial fastening applications.
Installation is performed by mechanical technicians, pipefitters, or maintenance professionals using standard 3/4 inch hex wrenches or sockets. Verify thread engagement and ensure mating hardware is also stainless or a compatible alloy to avoid galvanic corrosion. Torque to values specified by the equipment manufacturer or applicable structural code. Power down or de-energize any associated equipment before accessing fastened assemblies in energized systems.
