Value Collection 721019PR Flat Socket Cap Screw 0-80 1 in

Product Description

The VALUE COLLECTION 721019PR is a flat socket cap screw designed for precision fastening applications where a flush or countersunk installation is required. This screw features a 82-degree flat head driven by a hex socket tool, and is manufactured from alloy steel with a black oxide finish for corrosion resistance in controlled environments. The thread is size 0-80 UNF, with a 1-inch overall length and partial threading along the shank. It conforms to ASME/ANSI B18.3 and ASTM F835 standards. Machinists, toolmakers, and mechanical assembly technicians commonly install these fasteners in tight-clearance or flush-mount applications.

These flat socket cap screws are suited for use in precision machine components, jigs, fixtures, and mechanical assemblies where the fastener head must sit flush with or below the work surface. The 0-80 UNF thread designation makes this screw appropriate for fine-thread applications in small, precise assemblies. The hex socket drive allows for torque application in recessed or confined spaces. The black oxide finish is compatible with applications where moderate corrosion protection is acceptable and where a low-reflectance surface is preferred.

Key Features

• 82-degree flat head profile for countersunk, flush-mount installation
• Hex socket drive for use with standard Allen or hex key tools in confined spaces
• 0-80 UNF fine thread for precise engagement in small assemblies
• Alloy steel construction for strength in mechanical fastening applications
• Black oxide finish provides moderate corrosion resistance and low-glare surface
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 0-80 UNF flat socket cap screw for use in precision mechanical assemblies, fixtures, and equipment requiring a countersunk fastener of this thread size and length.

Installation Notes

Installation should be performed by qualified machinists or mechanical assembly technicians familiar with fine-thread fastener applications. Ensure the mating threaded hole is clean and properly tapped to 0-80 UNF before installation. Use the correct hex key size to avoid rounding the socket drive. Do not apply excessive torque, as alloy steel fasteners at this thread size are susceptible to overloading in shallow or blind holes.
