Value Collection 581008PR Hex Socket Cap Screw 0-80 Unf

Product Description

The VALUE COLLECTION 581008PR is a hex socket cap screw designed for precision fastening in tight-clearance applications. It features a 0-80 UNF thread — the finest standard unified thread series — and a 3/4 inch length under head with full threading along the entire shank. The drive is a hex socket type, requiring an appropriately sized hex key or Allen driver for installation and removal. Constructed from alloy steel with a black oxide finish, this fastener delivers solid mechanical strength while the coating provides a baseline level of corrosion resistance. It is suited for instrument assembly, electronics enclosures, small mechanical assemblies, and precision tooling work.

This screw is intended for applications requiring a miniature, fine-pitch fastener where space is limited and controlled torque is essential. Common use cases include instrument panels, optical equipment, small machinery guards, and precision metal assemblies. The 0-80 thread pitch is standard in instrumentation and electronics trades. Sold in multiples of 100 per order with a package quantity of 1, making it appropriate for shop stock or recurring production use.

Key Features

• 0-80 UNF thread — fine pitch for maximum thread engagement in thin materials
• Fully threaded shank provides consistent clamping along the full 3/4 inch length under head
• Hex socket drive for precise torque application and use in recessed or confined spaces
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish reduces light reflection and offers mild corrosion resistance in dry environments

Compatibility

Designed as an OEM-style replacement or standard stock fastener for precision assemblies requiring a 0-80 UNF hex socket cap screw with a 3/4 inch length under head.

Installation Notes

Installation is typically performed by machinists, instrument technicians, or assembly trades using a properly sized hex key or T-handle driver. Ensure the mating threaded hole is clean and correctly tapped to 0-80 UNF before installation to avoid cross-threading. De-energize or power down any equipment before fastening work on live assemblies. Do not use power drivers without torque limiting controls on fine-pitch miniature fasteners to prevent thread damage or fastener failure.
