Value Collection 721229PR Flat Socket Cap Screw 7/16-20

Product Description

The VALUE COLLECTION 721229PR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 82-degree flat head driven by a 1/4-inch hex socket, and is fully threaded along its 1-1/2-inch overall length with a 7/16-20 UNF thread. Manufactured from alloy steel with a black oxide finish, it delivers solid tensile strength and moderate corrosion resistance in a low-profile form. This screw meets ASME/ANSI B18.3 and ASTM F835 standards, making it suitable for precision mechanical assemblies, tooling fixtures, and machine components where head protrusion must be minimized.

This fastener is used in applications where a countersunk socket drive screw is required and the mating material must sit flush with or below the fastener head. Common installations include machine tool assemblies, jigs, fixtures, and structural mechanical joints in industrial and manufacturing environments. The black oxide finish provides mild corrosion protection and reduces light reflection, making it a practical choice for tooling and machinery maintenance work.

Key Features

• 82-degree flat head profile allows flush seating in countersunk holes
• 1/4-inch hex socket drive for precise torque application with standard Allen keys or hex drivers
• Fully threaded 1-1/2-inch overall length for maximum thread engagement
• 7/16-20 UNF thread form for fine-pitch, high-clamp-load applications
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 standards
• Black oxide finish provides mild corrosion resistance and matte appearance

Compatibility

Designed as a standard UNF-thread flat socket cap screw for use in any application requiring a 7/16-20 countersunk hex socket fastener per ASME/ANSI B18.3.

Installation Notes

Install using a calibrated 1/4-inch hex key or socket driver. Ensure the mating hole is countersunk to the correct 82-degree angle before installation. Power down or de-energize any equipment before performing fastener service on live assemblies. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for alloy steel UNF fasteners.
