Value Collection 592475BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 592475BR is a hex socket cap screw designed for high-strength fastening applications requiring corrosion resistance. Sized at 7/8-9 UNC with a 2-3/4 inch length under head, this screw is fully threaded and driven with a 3/4 inch hex key. It is manufactured from 18-8 austenitic stainless steel (Material Grade A2) with a bright uncoated finish, meeting ASME/ANSI B18.3 and ASTM F837 standards. Machinists, millwrights, pipefitters, and maintenance mechanics use this fastener where thread engagement, corrosion resistance, and socket-drive access are all required in a single cap screw.

This cap screw is suited for general industrial, marine, food-processing, and chemical-plant environments where stainless steel fasteners are specified. Full threading along the shank length allows engagement across varying material thicknesses without a grip-length limitation. Typical applications include machine frames, pump housings, pipe flanges, and structural assemblies where a flush or low-profile socket head is preferred over a hex bolt head. Sold individually, this screw is appropriate for both production use and maintenance replacement applications.

Key Features

• 7/8-9 UNC thread size with full threading along the entire shank
• 2-3/4 inch length under head for adequate thread engagement in thick stock
• 3/4 inch hex socket drive for high torque input with standard Allen keys or socket tools
• 18-8 austenitic stainless steel construction, Material Grade A2, for corrosion resistance
• Bright uncoated finish — no plating to flake, chip, or add dimensional variation
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as a direct-fit replacement or new-installation cap screw wherever a 7/8-9 UNC hex socket head cap screw conforming to ASME/ANSI B18.3 and ASTM F837 is specified.

Installation Notes

Installation requires a 3/4 inch hex key or socket-head driver rated for the torque demand of a 7/8-9 UNC fastener. Power down, de-energize, and isolate any equipment before performing fastener service on mechanical assemblies. Verify thread condition in the mating hole before installation — cross-threading stainless steel fasteners can cause galling that is difficult to recover. Follow applicable torque specifications from the equipment manufacturer or applicable ASME standards for the joint material and service condition.
