Value Collection 592157PR Hex Socket Cap Screw 6-40 Unf

Product Description

The VALUE COLLECTION 592157PR is a hex socket cap screw designed for precision fastening applications requiring a secure, flush-drive connection. Sized at 6-40 UNF thread with a 1 inch length under head, this screw is fully threaded from tip to head. The 7/64 inch hex drive accepts a standard hex key or Allen wrench. Constructed from 18-8 austenitic stainless steel (Grade A2), it delivers solid corrosion resistance in wet, outdoor, and mildly chemical environments. It meets ASME/ANSI B18.3 and ASTM F837 dimensional and material standards. Suitable for trade and industrial assembly work where a low-profile socket cap head and fine thread engagement are required.

This fastener is used in light mechanical assemblies, HVAC equipment panels, plumbing fixture mounting, electrical enclosures, and general industrial fabrication. The 6-40 UNF fine thread pitch provides greater pull-out strength and finer adjustment compared to coarse thread equivalents of the same diameter. Fully threaded construction makes it suitable for thin materials and through-hole applications. These screws are sold individually with a minimum order quantity of 100 pieces, making them appropriate for shop stock, service truck inventory, or production assembly use.

Key Features

• 6-40 UNF fine thread for higher thread engagement and pull-out resistance
• 1 inch length under head, fully threaded for maximum engagement in thin materials
• 7/64 inch hex socket drive compatible with standard Allen keys and hex bit drivers
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance in humid or wet environments
• Meets ASME/ANSI B18.3 and ASTM F837 standards for dimensional accuracy and material performance

Compatibility

Designed as a standard 6-40 UNF hex socket cap screw for use in any application requiring an ASME/ANSI B18.3 compliant fastener with a 7/64 inch hex drive and 1 inch length under head.

Installation Notes

Install with a 7/64 inch hex key or a matching hex bit driver. Ensure mating threads are clean and free of debris before driving. Do not overtighten stainless steel fasteners, as the material is susceptible to galling under excessive torque without lubrication. For structural or code-governed assemblies, consult the applicable mechanical or equipment standard for required fastener specifications.
