Value Collection 592187PR Hex Socket Cap Screw 8-36 Unf

Product Description

The VALUE COLLECTION 592187PR is a hex socket cap screw designed for applications requiring precise threading and corrosion resistance. Threaded 8-36 UNF, it features a 5/8 inch length under head and a 9/64 inch hex drive. Manufactured from 18-8 austenitic stainless steel (Grade A2) with a bright uncoated finish, this fastener meets ASME/ANSI B18.3 and ASTM F837 standards. It is fully threaded along its length, making it well suited for secure clamping in close-tolerance assemblies. Machinists, maintenance technicians, and trade professionals working in mechanical, HVAC, plumbing, and electrical panel applications commonly specify this size and material grade.

This screw is used in light mechanical assemblies, instrument enclosures, and equipment panels where a fine-thread UNF fastener with a low-profile socket head is required. The 8-36 UNF thread pitch provides finer engagement than UNC equivalents, improving holding strength in thinner materials and reducing the risk of loosening under vibration. Stainless steel construction makes this fastener suitable for moist or corrosive environments where carbon steel fasteners would be inappropriate.

Key Features

• 8-36 UNF thread for fine-pitch, high-engagement fastening
• 5/8 inch length under head — fully threaded along entire shank
• 9/64 inch hex socket drive for use with standard hex keys or Allen drivers
• 18-8 austenitic stainless steel, Grade A2 — corrosion resistant and non-magnetic
• Bright uncoated finish — no plating to affect thread tolerance
• Meets ASME/ANSI B18.3 and ASTM F837 dimensional and material standards

Compatibility

Designed as a standard 8-36 UNF hex socket cap screw conforming to ASME/ANSI B18.3, suitable for use in any application requiring a Grade A2 stainless steel socket head cap screw of this thread size and length.

Installation Notes

Install with a 9/64 inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Do not overtorque — stainless steel fasteners are susceptible to galling; applying an appropriate anti-seize compound to the threads is standard practice. Power down and de-energize any equipment before accessing fastened assemblies in electrical or mechanical enclosures.
