Value Collection 204229 Hex Head Cap Screw 3/8-16 2-1/2 in 316 Ss

Product Description

The VALUE COLLECTION 204229 is a 3/8-16 x 2-1/2 inch hex head cap screw machined from Grade 316 stainless steel. The 3/8-16 thread designation indicates a 3/8-inch nominal diameter with 16 threads per inch on a Unified National Coarse (UNC) thread form. Length is measured under the head at 2-1/2 inches. The 9/16-inch hex drive size accepts standard hex sockets and wrenches. Grade 316 stainless steel provides elevated corrosion resistance compared to Grade 304, making this fastener appropriate for wet, chemical, or marine environments. Installed by maintenance technicians, plumbers, pipefitters, and mechanical contractors wherever corrosion-resistant threaded fasteners are required.

This cap screw is suited for general mechanical assembly, pipe flange connections, equipment mounting, and structural fastening in corrosive or high-moisture environments. Typical applications include HVAC equipment mounting in coastal or chemical plant settings, plumbing fixture and pump assembly, pool equipment installations, and food-service or sanitary process equipment where stainless hardware is specified. The UNC thread form is the most common inch-series thread standard and mates with standard 3/8-16 nuts and tapped holes.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• 3/8-16 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• 2-1/2 inch length under head suits medium-depth fastening applications
• 9/16 inch hex drive accepts standard sockets and combination wrenches
• Inch measurement system throughout for direct use in standard trade applications

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 3/8-16 UNC thread, 2-1/2 inch length under head, Grade 316 stainless steel fastener.

Installation Notes

Installation requires a 9/16-inch socket or open-end wrench. De-energize, depressurize, or shut off any system before fastener replacement or assembly work. Apply anti-seize compound when joining stainless steel fasteners to stainless threaded components to prevent galling. Follow applicable mechanical, plumbing, or electrical codes for fastener specifications in structural or pressure-boundary applications.
