Value Collection 592481BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 592481BR is a hex socket cap screw designed for high-strength fastening in mechanical, structural, and industrial assembly applications. Featuring a 7/8-9 UNC thread form and a 4-inch length under head, this fastener is partially threaded to allow for controlled clamping force in bolted joint applications. The 3/4-inch hex drive socket head accommodates standard hex keys and Allen drive tools for reliable torque delivery. Constructed from 18-8 austenitic stainless steel (Grade A2), it provides corrosion resistance suitable for wet, chemical, or outdoor environments where carbon steel fasteners would be prone to rust.

This cap screw is suited for use in manufacturing, fabrication, maintenance, and mechanical assembly where stainless steel hardware is required. The 7/8-9 UNC coarse thread is a common standard in heavy-duty bolted connections and is compatible with standard UNC-tapped holes of the same designation. The bright, uncoated finish means no plating interference with thread tolerances. This fastener is appropriate for use by machinists, millwrights, maintenance technicians, and industrial assemblers working to ASME or ASTM fastener standards.

Key Features

• 7/8-9 UNC coarse thread for compatibility with standard tapped holes
• 4-inch length under head for use in thicker material stackups
• Partially threaded shank provides a bearing surface for precise joint alignment
• 3/4-inch hex socket drive for use with standard hex keys or Allen drivers
• 18-8 austenitic stainless steel (Grade A2) for corrosion resistance in harsh environments
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed for use in standard 7/8-9 UNC tapped holes per ASME/ANSI B18.3 specifications, suitable as a direct replacement or new installation fastener in any application requiring a stainless steel hex socket cap screw of this thread size and length.

Installation Notes

Install using a calibrated hex key or Allen driver sized to 3/4 inch; do not use worn or undersized drivers that can strip the socket. Verify the mating tapped hole thread class and depth before installation. Power down or de-energize any associated equipment before performing fastener work on mechanical assemblies. Follow applicable ASME or facility torque specifications for the joint material and application.
