Value Collection 592473BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 592473BR is a hex socket cap screw designed for fastening applications that demand corrosion resistance and reliable clamping strength. Featuring a 7/8-9 UNC thread size and a 2-1/2 inch length under head, this fastener is fully threaded and driven with a 3/4 inch hex key. Manufactured from 18-8 austenitic stainless steel (Material Grade A2) and left uncoated with a bright finish, it meets ASME/ANSI B18.3 and ASTM F837 standards. Mechanical contractors, millwrights, maintenance technicians, and fabricators rely on socket cap screws like this when access is limited to axial drive.

This screw is suited for use in structural, mechanical, and industrial assembly applications where a recessed drive head is preferred to minimize profile or accommodate tight clearances. The 7/8-9 UNC coarse thread pattern provides fast engagement and strong pull-out resistance in ferrous and non-ferrous base materials. The stainless steel construction makes it appropriate for environments with moisture exposure, mild chemical exposure, or food-adjacent service conditions.

Key Features

• 7/8-9 UNC coarse thread for fast engagement and strong holding power
• 2-1/2 inch length under head, fully threaded for maximum thread engagement
• 3/4 inch hex socket drive for high torque input with standard hex keys or sockets
• 18-8 austenitic stainless steel, Material Grade A2 for corrosion resistance
• Bright/uncoated finish meets ASME/ANSI B18.3 and ASTM F837 standards
• Low-profile socket head allows installation in recessed or confined spaces

Compatibility

Designed as an OEM-style or MRO replacement hex socket cap screw for general mechanical and structural fastening applications requiring a 7/8-9 UNC fully threaded fastener in stainless steel.

Installation Notes

Install with a calibrated 3/4 inch hex key or hex bit socket; do not use damaged or undersized drivers that can strip the socket. Verify thread engagement depth in the mating component before torquing. Stainless fasteners are susceptible to galling during installation — apply an appropriate anti-seize compound to the threads when fastening into stainless or aluminum. Follow applicable mechanical codes and equipment manufacturer torque specifications for the joint being assembled.
