Value Collection 211003PR Flat Socket Cap Screw 0-80 Unf

Product Description

The VALUE COLLECTION 211003PR is a flat socket cap screw designed for precision fastening applications where a flush or countersunk installation is required. It features an 82-degree flat head with a hex socket drive, allowing installation with a standard hex key. The screw is fully threaded with a 0-80 UNF thread and measures 0.25 inches in overall length. Manufactured from alloy steel with a black oxide finish, it provides moderate corrosion resistance and is suited for tight-tolerance assemblies in mechanical, instrumentation, and light industrial settings. Machinists, assemblers, and maintenance technicians typically install this fastener.

This screw is used in applications where the fastener head must sit flush with or below the surface of the mating material, such as in instrument panels, jigs, fixtures, precision machinery, and electronic enclosures. The 0-80 thread size is one of the smallest unified thread forms, making this part appropriate for miniature assemblies that require fine-pitch engagement. It is sold in a minimum order quantity of 100 pieces per order, with each package containing 1 piece.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• Hex socket drive accepts standard hex keys for precise torque application
• Fully threaded 0-80 UNF for maximum thread engagement over the full length
• Alloy steel construction provides strength suited for small-fastener load requirements
• Black oxide finish reduces light reflection and offers mild corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-series flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835, compatible with any application requiring a 0-80 UNF fully threaded flat socket cap screw with an 82-degree countersink angle.

Installation Notes

Install using the correctly sized hex key to avoid stripping the drive socket, which is especially critical at this miniature thread size. Ensure the mating hole is countersunk to an 82-degree angle to achieve full head seating. Power down any equipment before fastener service in electrical or instrumentation assemblies. Follow applicable ASME B18.3 specifications for proper installation procedure.
