Value Collection 592149PR Hex Socket Cap Screw 6-40 Unf

Product Description

The VALUE COLLECTION 592149PR is a hex socket cap screw designed for precision fastening applications requiring a compact, high-strength connection. Threaded 6-40 UNF and fully threaded along its 3/8 inch length under head, this screw accepts a 7/64 inch hex drive and is manufactured from 18-8 austenitic stainless steel (Grade A2). That material choice delivers solid corrosion resistance and adequate tensile strength for mechanical assemblies in environments where mild chemical or moisture exposure is a concern. It meets ASME/ANSI B18.3 and ASTM F837 dimensional and mechanical standards. Installers in HVAC, plumbing, electrical, and general mechanical trades reach for socket cap screws where clearance is tight and a standard hex-head driver will not fit.

This fastener is suited for light mechanical assemblies, panel mounting, equipment enclosures, and fixture fabrication where a fine-thread UNF profile is specified. The 6-40 UNF thread pitch provides tighter thread engagement per inch than a comparable UNC thread, making it a common choice in thin-material or precision-fit applications. Sold individually per package with a minimum order quantity of 100 pieces, this screw is intended for use by tradespeople and maintenance technicians sourcing fasteners in volume for recurring service or installation work.

Key Features

• 6-40 UNF fully threaded profile for tight thread engagement in fine-thread applications
• 3/8 inch length under head suits thin panel and bracket mounting scenarios
• 7/64 inch hex socket drive for use with standard hex keys or Allen-type bit drivers
• 18-8 austenitic stainless steel (Grade A2) construction for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as an OEM-style replacement or maintenance fastener for mechanical assemblies specifying a 6-40 UNF hex socket cap screw with a 3/8 inch length under head and 7/64 inch drive.

Installation Notes

Install using a calibrated 7/64 inch hex key or socket bit; confirm the mating threaded hole is clean and free of debris before driving. Power down or de-energize any equipment before accessing fastener locations on electrical enclosures or HVAC components. Do not overtighten stainless fasteners in stainless threaded holes without anti-seize compound, as galling can occur. Follow applicable equipment manufacturer torque guidance and relevant trade codes for the assembly type being serviced.
