Value Collection 721004PR Flat Socket Cap Screw 0-80 Unf

Product Description

The VALUE COLLECTION 721004PR is a flat socket cap screw designed for precision fastening applications where a flush or countersunk head profile is required. Sized at 0-80 UNF thread with an overall length of 5/8 inches, this fully threaded fastener is machined from alloy steel and finished with black oxide for corrosion resistance and a low-reflectance appearance. The 82-degree flat head countersinks flush with the work surface, and the hex socket drive allows torque application in tight clearance areas. This fastener meets ASME/ANSI B18.3 and ASTM F835 standards. It is appropriate for use by machinists, mechanical assemblers, and trade technicians working with precision components.

This screw is suited for light-load, fine-thread applications in mechanical assemblies, instrumentation, electronics enclosures, and similar precision hardware contexts. The 0-80 UNF thread designation makes it one of the finest standard inch-series threads available, commonly found in optical, medical device, and small-equipment assemblies. Black oxide finish provides mild corrosion protection in dry or mildly humid indoor environments. Sold individually per package, with a minimum order quantity of 100 pieces per order.

Key Features

• 82-degree flat head countersinks flush with the mating surface for a clean, low-profile finish
• Hex socket drive enables torque application in recessed or confined spaces
• Fully threaded along the 5/8-inch overall length for maximum thread engagement
• Alloy steel construction provides strength appropriate for fine-thread fastening applications
• Black oxide finish reduces surface reflectance and provides mild corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for assemblies requiring a 0-80 UNF fully threaded flat socket cap screw with an 82-degree head angle and hex socket drive in inch-series hardware.

Installation Notes

Installation requires a correctly sized hex key or Allen driver matched to the 0-80 socket head to avoid cam-out and fastener damage. Always verify the countersink angle of the mating part matches the 82-degree head geometry before installation. Power down or de-energize any equipment before accessing internal fasteners on electrical or mechanical assemblies. Consult the equipment manufacturer torque specifications for the assembly being serviced.
