Value Collection 721215PR Flat Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION 721215PR is a flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies. The 82-degree flat head seats flush with the mating surface, and the 7/32-inch hex socket drive allows precise torque application with a standard hex key. Manufactured from alloy steel with a black oxide finish, this screw provides corrosion resistance suitable for indoor and protected industrial environments. It is fully threaded along its 1-3/4-inch overall length on a 3/8-24 UNF fine thread form, conforming to ASME/ANSI B18.3 and ASTM F835 dimensional and mechanical standards.

This screw is used in precision mechanical, industrial, and machinery applications where a recessed drive fastener is required to sit flush with or below the workpiece surface. The fine 3/8-24 UNF thread pitch is preferred in applications requiring higher thread engagement strength or fine clamping adjustment. Typical installers include maintenance mechanics, machine builders, and industrial assemblers working on tooling, fixtures, and structural mechanical components.

Key Features

• 82-degree flat head for flush countersunk seating
• 7/32-inch hex socket drive for precise torque control
• 3/8-24 UNF fine thread for high engagement strength
• Fully threaded along the 1-3/4-inch overall length
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835
• Black oxide finish for moderate corrosion resistance in protected environments

Compatibility

Designed as a standard replacement or build-spec flat socket cap screw for applications requiring a 3/8-24 UNF fully threaded countersunk fastener conforming to ASME/ANSI B18.3 and ASTM F835.

Installation Notes

Installation is performed by mechanics or industrial assemblers using a 7/32-inch hex key or hex bit driver. Ensure the mating countersink is machined to an 82-degree included angle for proper head seating before driving the fastener. Power off or lock out any equipment before fastening in or near moving assemblies, following applicable OSHA lockout/tagout procedures. Do not exceed the rated mechanical properties of the alloy steel by applying impact installation methods that could compromise thread integrity.
