Value Collection 581004PR Hex Socket Cap Screw 0-80 Unf

Product Description

The VALUE COLLECTION 581004PR is a hex socket cap screw designed for precision fastening in tight-clearance applications. Threaded to the 0-80 UNF standard, this screw measures 1/2 inch in length under the head and is fully threaded along that length. The hex drive requires an allen key or hex bit driver sized to the 0.05-inch drive. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength and modest corrosion resistance in low-moisture environments. It is installed by machinists, maintenance technicians, and assembly professionals working on instruments, fixtures, electronics enclosures, or light mechanical assemblies.

This screw is suited for applications where fine-thread engagement and minimal fastener profile are required. The 0-80 UNF thread form is common in precision instrument assembly, optics mounts, electronics hardware, and small mechanical sub-assemblies. The black oxide coating reduces surface reflectance and provides mild corrosion protection in indoor or controlled environments. Sold individually, with a minimum order quantity of 100 pieces, making it appropriate for shop stock or production-run sourcing.

Key Features

• 0-80 UNF thread for fine-pitch, high-engagement fastening in small assemblies
• Fully threaded along the 1/2-inch length under head for maximum thread engagement
• Alloy steel construction provides high tensile strength in a small form factor
• Black oxide finish reduces reflectance and offers mild corrosion resistance
• Hex socket drive (0.05 inches) allows torquing in recessed or confined spaces
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for precision assemblies requiring a 0-80 UNF fully threaded hex socket cap screw in alloy steel.

Installation Notes

Installation is performed by machinists or assembly technicians using a correctly sized hex key or driver bit matching the 0.05-inch drive. Ensure mating threads are clean and free of debris before installation. Apply thread engagement appropriate to the base material — alloy steel screws into softer materials such as aluminum require careful torque control to avoid stripping. Follow applicable assembly specifications or torque tables for 0-80 fasteners per ASME B18.3 guidance.
