Value Collection 592020PR Hex Socket Cap Screw 1-72 Unf

Product Description

The VALUE COLLECTION 592020PR is a hex socket cap screw designed for precision fastening in tight-clearance applications. It features a 1-72 UNF thread — a fine-pitch unified thread commonly used in instrumentation, electronics, and small mechanical assemblies — and accepts a 1/16 inch hex drive key for installation. The screw is fully threaded along its 5/16 inch length under head and is manufactured from 18-8 austenitic stainless steel, providing corrosion resistance in both indoor and moderate outdoor environments. Licensed tradespeople and assembly technicians working on small-bore mechanical or electronic equipment will find this fastener suited to close-tolerance work.

This fastener is commonly used in light industrial, instrumentation, HVAC controls, and precision equipment assembly where a fine-thread cap screw with corrosion resistance is required. The 1-72 UNF thread designation is standard in low-voltage control hardware, panel components, and miniature mechanical subassemblies. It is sold in a minimum order quantity of 100 pieces per order, with a package quantity of 1 unit per package.

Key Features

• 1-72 UNF fine-pitch thread for precise engagement in small tapped holes
• Fully threaded 5/16 inch length under head for maximum thread engagement
• 1/16 inch hex drive for use with standard hex keys or Allen drivers
• 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 standard-specification hex socket cap screw for applications requiring a 1-72 UNF thread size and 5/16 inch length under head in stainless steel.

Installation Notes

Installation is performed by assembly technicians or qualified tradespeople using a 1/16 inch hex key or Allen driver. Ensure the mating tapped hole is clean and correctly sized for a 1-72 UNF thread before installation. Do not overtighten — small-diameter fasteners in stainless steel are susceptible to galling; apply an appropriate anti-seize compound if repeated removal is expected. Follow applicable ASME or equipment manufacturer torque guidelines for the specific assembly.
