Value Collection 208956C Hex Head Cap Screw 3/8-16 X 4 in

Product Description

The VALUE COLLECTION 208956C is a 3/8-16 hex head cap screw machined from 18-8 stainless steel for corrosion-resistant fastening in structural and mechanical assemblies. The screw measures 4 inches under the head and carries a Unified National Coarse (UNC) thread form, making it compatible with standard 3/8-16 tapped holes and hex nuts. The 9/16-inch hex drive accepts standard wrenches and sockets used by plumbers, HVAC technicians, equipment installers, and general trade professionals working on brackets, flanges, equipment frames, and support structures where moisture or chemical exposure is a concern.

This cap screw is suited for indoor and outdoor mechanical installations where 18-8 stainless steel provides adequate resistance to rust and mild corrosive environments. Common applications include securing HVAC equipment mounting brackets, plumbing pipe supports, pool equipment frames, and electrical enclosure hardware. The UNC thread standard ensures reliable engagement with commercially available nuts, inserts, and tapped steel or stainless components across residential and light commercial jobsites.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and outdoor environments

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw for use with any compatible 3/8-16 threaded nut, insert, or tapped component following inch-standard fastener specifications.

Installation Notes

Installation requires a 9/16-inch wrench or socket driver. Follow applicable torque guidelines for 3/8-16 stainless fasteners per the equipment manufacturer or relevant mechanical code. Avoid over-torquing stainless steel fasteners, as galling can permanently seize the thread. Use anti-seize compound where dissimilar metals or repeated disassembly is expected.
