Value Collection 451141BR Hex Head Cap Screw 3/4-10 X 7 in Grade 8

Product Description

The VALUE COLLECTION 451141BR is a Grade 8 steel hex head cap screw with a 3/4-10 UNC thread and a 7-inch length under head. Manufactured to ASME B18.2.1 standards, it features partial threading and a bright uncoated finish. Grade 8 steel provides high tensile strength suitable for demanding structural and mechanical fastening applications. The hex drive requires a 1-1/8 inch wrench. This fastener is typically installed by millwrights, pipefitters, mechanical contractors, and maintenance technicians working on heavy equipment, structural assemblies, and industrial machinery.

This cap screw is used in applications where high-strength fastening is required, including structural steel connections, heavy equipment mounting, machinery frames, and industrial maintenance work. The partial threading is appropriate for clamping applications where the unthreaded shank provides a cleaner bearing surface and reduces the risk of thread engagement in the grip area. It is suited for both new construction and field repair scenarios across manufacturing, industrial, and commercial settings.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/4-10 UNC thread meets standard inch fastener sizing
• 7-inch length under head for deep-reach or thick-stack fastening
• Partially threaded shank suits clamping and bearing-surface applications
• Bright uncoated finish — no coating buildup to affect dimensional tolerances
• Manufactured to ASME B18.2.1 dimensional standards

Compatibility

Designed as an OEM-style replacement or standard-use fastener compatible with any assembly requiring a 3/4-10 UNC hex head cap screw at 7-inch length under head, conforming to ASME B18.2.1.

Installation Notes

Installation should be performed by qualified tradespeople following applicable mechanical and structural codes. Use a properly rated 1-1/8 inch open-end, box-end, or impact wrench socket when driving this fastener. De-energize, depressurize, or mechanically isolate the assembly before fastener replacement. Do not substitute a lower-grade fastener in applications specified for Grade 8.
