Value Collection R88444619 Hex Head Cap Screw 7/8-9 X 9 in

Product Description

The VALUE COLLECTION R88444619 is a partially threaded hex head cap screw designed for heavy-duty fastening applications where corrosion resistance is critical. Manufactured from Grade 316 stainless steel, this fastener provides superior resistance to chlorides, salt water, and harsh chemical environments compared to standard 304 stainless. The 7/8-9 thread size follows the Unified National Coarse (UNC) standard, and the 9-inch length under head accommodates thick assemblies, flanges, and structural connections. The hex drive head allows installation and removal with standard wrenches or impact tools. The uncoated finish maintains the natural surface of the 316 alloy without added plating or treatment.

This cap screw is suited for marine, chemical processing, food service, and industrial environments where moisture, saltwater exposure, or aggressive chemicals are present. Partially threaded shanks are preferred when clamping force needs to be distributed across a smooth shank section rather than fully threaded engagement. Licensed tradespeople and maintenance technicians in plumbing, mechanical, and structural installation work commonly specify Grade 316 stainless fasteners when stainless hardware is required by code or project specification.

Key Features

• Grade 316 stainless steel for high corrosion resistance in marine and chemical environments
• 7/8-9 UNC thread standard ensures compatibility with standard hex nuts and tapped holes
• 9-inch length under head accommodates thick material assemblies
• Partially threaded shank provides a smooth bearing surface for improved clamping performance
• Uncoated finish preserves the natural 316 alloy surface without added coating
• Hex head design accepts standard wrenches and impact sockets

Compatibility

Designed for use with 7/8-9 UNC-threaded hex nuts and tapped holes in inch-standard fastening applications requiring Grade 316 stainless steel hardware.

Installation Notes

Installation is performed by mechanical or maintenance tradespeople using standard combination wrenches or impact tools sized for the hex head. Fastener torque should be determined by the engineer of record or applicable project specification, as no torque value was provided with this part. When used in structural or pressure-rated assemblies, follow applicable codes and verify thread engagement depth before final tightening. Inspect threads for damage before installation to ensure full engagement and proper clamping force.
