Value Collection R57001143 Hex Head Cap Screw 3/8-16 X 5 in

Product Description

The VALUE COLLECTION R57001143 is a fully threaded hex head cap screw designed for secure mechanical fastening in industrial, commercial, and trade applications. Sized at 3/8-16 x 5 inches with a UNC (Unified National Coarse) thread standard, this fastener is machined from 18-8 stainless steel and left uncoated, delivering solid corrosion resistance without added surface treatments. The full-thread configuration runs the entire 5-inch length under the head, maximizing thread engagement and load-bearing capacity across the full fastener length. Plumbers, HVAC technicians, electricians, and general contractors use this grade of fastener where moisture exposure or chemical contact rules out carbon steel hardware.

This cap screw suits a wide range of assembly and mounting applications in mechanical rooms, rooftop equipment, plumbing hangers, electrical enclosures, and similar environments where stainless hardware is specified. The 18-8 alloy grade is a standard austenitic stainless composition widely accepted in both residential and commercial mechanical system installations. It is suited for structural clamping, flange bolting, equipment mounting, and general-purpose fastening wherever a 3/8-16 UNC threaded fastener is called out in the build specification.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and chemically active environments
• Fully threaded shaft along the full 5-inch length under head for maximum thread engagement
• 3/8-16 UNC thread size is a widely specified coarse-thread standard in mechanical and structural applications
• Uncoated finish eliminates coating thickness variation and is compatible with standard 3/8-16 nuts and hardware
• Hex head drive accepts standard SAE hex wrenches and sockets for efficient installation and removal
• Weighs 0.3 pounds per unit, lightweight for field handling

Compatibility

Designed for use with standard 3/8-16 UNC threaded nuts, washers, and tapped holes conforming to Unified National Coarse thread specifications. Suitable for mechanical assemblies where 18-8 stainless steel fasteners are required.

Installation Notes

Installation is performed using a standard hex wrench or socket sized for a 3/8-inch hex head cap screw. De-energize or shut off all relevant systems before fastening hardware on or near electrical panels, HVAC equipment, or plumbing assemblies. Apply an anti-seize compound when torquing stainless fasteners into stainless tapped holes to prevent galling. Follow applicable mechanical, structural, or equipment codes for torque requirements specific to the assembly.
