Value Collection R40634421 Hex Socket Cap Screw 0-80 Unf

Product Description

The VALUE COLLECTION R40634421 is a 0-80 UNF hex socket cap screw designed for precision fastening applications requiring a fine thread profile and compact drive geometry. It features a hex socket drive measuring 0.05 inches and a length under head of 0.25 inches. Manufactured from 18-8 stainless steel, this fastener provides solid corrosion resistance in environments where mild acids, moisture, or humidity are present. It is installed using a hex key or Allen driver sized to the 0.05-inch socket. Electricians, instrument techs, and mechanical assemblers commonly use fasteners in this size class for panel work, equipment enclosures, and precision mechanical assemblies.

This screw is suited for light-duty precision fastening in instrumentation, small electronics enclosures, control panels, and similar assemblies where a very fine thread is required. The 0-80 thread designation is among the finest unified thread series available, making it appropriate for thin-material and close-tolerance applications in both commercial and industrial settings. Its compact profile and stainless construction make it a reliable choice where space is constrained and mild corrosion resistance is needed.

Key Features

• 0-80 UNF thread for fine-pitch, close-tolerance fastening
• Hex socket drive for torque application in confined spaces
• 18-8 stainless steel construction resists corrosion and oxidation
• 0.25-inch length under head suits thin-material assemblies
• Compact 0.05-inch drive size matches precision hex key tooling

Compatibility

Designed as a standard 0-80 UNF hex socket cap screw for use in precision mechanical assemblies, instrumentation housings, and control enclosures requiring fine unified thread fasteners.

Installation Notes

Installation requires a correctly sized hex key or Allen driver; using an ill-fitting driver risks stripping the socket. Verify thread engagement depth before fully seating the fastener to avoid cross-threading in tapped holes. Apply only moderate torque appropriate for the small fastener diameter to prevent thread failure in the mating material.
