Value Collection -30604-37 Hex Head Cap Screw 7/8-9 X 5 in

Product Description

The VALUE COLLECTION -30604-37 is a partially threaded hex head cap screw designed for general industrial and mechanical fastening applications. Manufactured from Grade 316 stainless steel, it delivers strong corrosion resistance in wet, chemical, and marine environments. The fastener measures 7/8-9 thread size with a 5-inch length under head and follows the Unified National Coarse (UNC) thread standard. The uncoated finish maintains dimensional accuracy and is suitable for applications where coatings could compromise fit or introduce contamination. Licensed tradespeople and maintenance technicians commonly install this fastener in structural, plumbing, and equipment assemblies requiring reliable stainless hardware.

This cap screw is well suited for residential and commercial maintenance work, marine installations, food-processing equipment, chemical handling systems, and any application where standard carbon steel fasteners would be subject to rust or corrosion. The Grade 316 alloy is a common choice in coastal and high-humidity environments. The partially threaded shank provides a smooth bearing surface useful in bolted joints where shear load transfer is a priority. This item is sold individually with a minimum order quantity of 5 pieces.

Key Features

• Grade 316 stainless steel construction for elevated corrosion resistance in harsh environments
• 7/8-9 UNC thread size for compatibility with standard inch-series nuts and tapped holes
• 5-inch length under head accommodates thicker material stacks and deep joint assemblies
• Partially threaded shank provides a smooth grip section for improved shear load performance
• Uncoated finish preserves true dimensions and avoids coating-related clearance issues

Compatibility

Designed as a standard inch-series hex head cap screw for use with 7/8-9 UNC nuts, threaded inserts, and tapped holes conforming to the Unified National Coarse thread standard.

Installation Notes

Installation is typically performed by licensed millwrights, pipefitters, plumbers, or maintenance technicians using standard hex wrenches or impact tools sized for a 7/8-9 hex head fastener. Always verify thread engagement depth and joint design before final tightening. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound to the threads before assembly to prevent thread damage. Follow applicable structural or mechanical codes for the specific installation type.
