Value Collection R52000254 Hex Socket Cap Screw 0-80 Unf

Product Description

The VALUE COLLECTION R52000254 is a hex socket cap screw designed for precision fastening applications requiring a compact, high-strength connection. Threaded to the 0-80 UNF standard, this screw measures 3/4 inches under the head and features partial threading along its length. The drive is a hex socket type, accepting standard hex keys or Allen drivers. Manufactured from 18-8 austenitic stainless steel (Material Grade A2), it provides solid corrosion resistance for indoor and light outdoor environments. This fastener meets ASME/ANSI B18.3 and ASTM F837 standards, making it suitable for applications where dimensional and mechanical consistency is required. Machinists, assemblers, and maintenance technicians are the typical installers.

This screw is suited for fine-thread fastening tasks in light mechanical assemblies, instrumentation, electronics enclosures, and precision equipment where a small-diameter, corrosion-resistant fastener is needed. The 0-80 UNF thread designation indicates an extremely fine pitch appropriate for thin-material or close-tolerance applications. Partial threading allows the unthreaded shank to act as a locating or clamping surface. This item is sold individually but carries a minimum order quantity of 100 units, making it appropriate for production, shop stock, or maintenance kits requiring a reliable supply of small-diameter fasteners.

Key Features

• 0-80 UNF thread size for fine-pitch, tight-tolerance fastening
• 3/4 inch length under head for moderate grip depth in small assemblies
• Partial threading provides an unthreaded shank for alignment and clamping applications
• Hex socket drive accepts standard hex keys for torque-controlled installation in confined spaces
• 18-8 austenitic stainless steel construction (Grade A2) for corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F837 dimensional and mechanical standards

Compatibility

Designed as a standard 0-80 UNF hex socket cap screw suitable for use in precision mechanical assemblies, instrumentation, and equipment requiring fine-thread stainless steel fasteners conforming to ASME/ANSI B18.3.

Installation Notes

Installation requires a correctly sized hex key or Allen driver matched to the socket size of this screw. Ensure mating threaded holes are tapped to the 0-80 UNF specification and are free of debris before installation. Do not over-torque small-diameter stainless steel fasteners, as galling of the threads can occur; applying an appropriate anti-galling lubricant is common practice. Power down or de-energize any equipment before performing fastener service on electrical or instrumentation assemblies.
