Value Collection 592055PR Hex Socket Cap Screw 3-56 Unf

Product Description

The VALUE COLLECTION 592055PR is a hex socket cap screw designed for precision fastening applications requiring a compact, high-strength threaded fastener. Built to ASME/ANSI B18.3 and ASTM F837 standards, it features a 3-56 UNF thread size with a fully threaded shank and a 5/64-inch hex drive. The body is machined from 18-8 austenitic stainless steel (Material Grade A2), providing solid corrosion resistance in exposed or high-humidity environments. At 1/4 inch length under head, this screw suits tight-clearance assemblies where space is limited and thread engagement depth matters.

This screw is well suited for light mechanical assemblies, instrument panels, electronics enclosures, and small-component fastening tasks encountered in HVAC controls, plumbing fixture hardware, and electrical panel work. The fine 56-thread-per-inch UNF pitch delivers strong clamping force in thin or precision-tapped material. Sold in multiples of 100 units per order with a package quantity of 1, it is appropriate for shops and technicians maintaining a stocked inventory of fine-thread fasteners for repeat service calls.

Key Features

• 3-56 UNF thread size with fully threaded shank for maximum thread engagement
• 5/64-inch hex (Allen) drive for use with standard hex key sets
• 1/4-inch length under head for compact, tight-clearance installations
• 18-8 austenitic stainless steel, Material Grade A2 for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for applications specifying a 3-56 UNF hex socket cap screw with a 1/4-inch length under head in stainless steel.

Installation Notes

Installation requires a 5/64-inch hex key or Allen driver. Confirm the mating tapped hole is clean and free of debris before threading to avoid cross-threading in fine UNF threads. When installing into aluminum or soft alloy components, apply controlled torque to prevent thread stripping. Power down any equipment fully before replacing fasteners on live panels or control assemblies.
