Value Collection 440680BR Hex Cap Screw 7/8-9 X 8 in Grade L9

Product Description

The VALUE COLLECTION 440680BR is a partially threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade L9 steel with a zinc yellow dichromate finish, this fastener delivers corrosion resistance alongside superior tensile strength suited to demanding service environments. The 7/8-9 UNC thread and 8-inch length under head make it appropriate for through-bolting heavy components where a full-thread fastener would not be suitable. Licensed tradespeople, maintenance mechanics, and industrial assemblers working with large-diameter fasteners will find this screw fits standard hex drive tooling with a 1-5/16-inch hex key size.

This fastener is used in heavy equipment assembly, structural steel connections, agricultural machinery, mining equipment, and similar applications requiring high-clamp-load fasteners. The partially threaded shank provides a smooth bearing surface through the joint, which is often required in shear-loaded connections. The zinc yellow dichromate coating offers a baseline level of corrosion protection appropriate for indoor and sheltered outdoor installations. It follows the Inch measurement system with UNC threading, making it compatible with standard American fastener tooling and hardware.

Key Features

• Zinc yellow dichromate finish offers corrosion resistance in industrial environments
• 7/8-9 UNC thread conforms to standard American inch-series thread specifications
• 1-5/16-inch hex key size fits standard industrial hex drive sockets and wrenches
• 8-inch length under head accommodates through-bolting of thick structural members

Compatibility

Designed as a standard-specification inch-series hex head cap screw for use in any assembly requiring a 7/8-9 UNC partially threaded fastener with an 8-inch length under head.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople familiar with large-diameter fastener torque procedures and applicable industry standards. Always verify thread engagement and joint material compatibility before installation. Use the correct 1-5/16-inch hex socket or wrench to avoid fastener damage. Follow applicable ASME, AISC, or equipment manufacturer torque specifications for Grade L9 fasteners, as these are not included with this product listing.
