Value Collection 592003PR Hex Socket Cap Screw 0-80 Unf

Product Description

The VALUE COLLECTION 592003PR is a hex socket cap screw designed for precision fastening applications requiring a compact drive interface and controlled thread engagement. This screw features a 0-80 UNF thread — one of the finest inch-series thread standards available — and measures 5/8 inches in length under head. It is fully threaded from the bearing surface to the tip, maximizing thread engagement across the full clamped length. Manufactured from 18-8 austenitic stainless steel (Grade A2), it provides corrosion resistance suitable for wet or chemically exposed environments. The hex socket drive accepts a standard hex key for installation in confined spaces where a wrenching perimeter is not practical. Installation professionals and precision assemblers in instrumentation, electronics, and light mechanical trades are the typical end users.

This screw is suited for fine-thread fastening tasks where vibration resistance and precise torque control matter. The 0-80 UNF thread pitch is common in optical equipment, instruments, small mechanical assemblies, and control panel hardware. Its small diameter and fully threaded body make it appropriate for thin-material applications where partial threading would reduce engagement. The stainless steel construction makes it a reliable choice for outdoor enclosures, humid environments, and applications where zinc-plated carbon steel would corrode prematurely.

Key Features

• 0-80 UNF thread — one of the finest inch-series thread standards, suited for precision assemblies
• Fully threaded body maximizes thread engagement across the full 5/8-inch length under head
• 18-8 austenitic stainless steel (Grade A2) provides corrosion resistance in wet and chemical environments
• Hex socket drive allows installation in tight clearance areas with a standard hex key
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards
• Minimum order quantity of 100 pieces supports production and service inventory needs

Compatibility

Designed as an OEM-style replacement or production fastener for assemblies requiring a 0-80 UNF hex socket cap screw with a 5/8-inch length under head in stainless steel.

Installation Notes

Install using a properly sized hex key or hex bit driver matched to the socket drive to avoid rounding the socket. Power down or de-energize any assembly before fastener service when working near electrical components. Follow applicable torque guidelines for 0-80 UNF stainless steel fasteners per ASME or equipment manufacturer documentation — stainless threads can gall if driven too fast or without lubrication. Do not mix with carbon steel fasteners in galvanic-sensitive assemblies.
