Value Collection 202970B Hex Head Cap Screw 3/8-16 X 3/4 in

Product Description

The VALUE COLLECTION 202970B is a hex head cap screw in 3/8-16 UNC thread with a 3/4-inch length under head, manufactured from Grade 316 stainless steel. Grade 316 stainless offers superior corrosion resistance compared to Grade 304, making it suitable for environments exposed to moisture, salt, chlorides, and chemicals. The 9/16-inch hex drive accepts standard hex wrenches and sockets for reliable installation torque. This fastener is suited for use by plumbers, pipefitters, HVAC technicians, and mechanical contractors working on equipment assemblies, flanges, brackets, and structural connections where corrosion resistance is a priority.

This cap screw is used in a wide range of trade and industrial applications where stainless fasteners are specified, including HVAC equipment mounting, plumbing and piping system flanges, pool and water treatment equipment, and coastal or marine-adjacent installations. The UNC thread form is the standard inch-series coarse thread, compatible with 3/8-16 tapped holes and standard 3/8-16 hex nuts and washers. This item is sold individually but carries a minimum order quantity of 25 pieces.

Installation Notes

Installation should be performed by a qualified technician or mechanic following the equipment manufacturer's torque specifications and applicable codes. Ensure the mating threaded hole or nut is also stainless or a compatible material to avoid galvanic corrosion in wet or chemical environments. Use appropriate anti-seize compound on stainless threads to prevent galling during installation. Inspect threads for damage before installation and do not force-thread into misaligned holes.
