Value Collection 721233PR Flat Socket Cap Screw 7/16-14

Product Description

The VALUE COLLECTION 721233PR is a flat socket cap screw designed for flush or countersunk fastening applications. It features an 82-degree flat head driven by a 1/4-inch hex socket and is fully threaded along its 7/8-inch overall length. The screw is machined from alloy steel and finished with black oxide for corrosion resistance and a low-reflectance appearance. Thread size is 7/16-14 UNC, conforming to ASME/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and maintenance technicians install this fastener where a smooth, flush surface is required after assembly.

This screw is suited for general industrial and mechanical assembly work where a recessed head profile is necessary. Its 82-degree flat countersink geometry matches standard countersunk hole patterns produced by common countersink drill bits. Typical applications include machine frames, fixtures, tooling plates, and equipment panels where the fastener head must sit flush with or below the mating surface. The black oxide finish makes it a common choice in low-moisture indoor industrial environments.

Key Features

• 82-degree flat head profile seats flush in standard countersunk holes
• 1/4-inch hex socket drive for use with standard hex keys or socket drivers
• Fully threaded 7/8-inch overall length for maximum thread engagement
• Alloy steel construction provides high tensile strength
• Black oxide finish reduces surface reflectance and offers mild corrosion resistance
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC replacement or new-installation flat socket cap screw for 7/16-14 threaded applications requiring an 82-degree countersunk hex socket head per ASME/ANSI B18.3.

Installation Notes

Install using a properly sized 1/4-inch hex key or hex socket driver to avoid rounding the drive recess. Ensure the mating countersink is machined to an 82-degree angle for full head contact and flush seating. De-energize and lock out any equipment before fastener installation or removal on live machinery per applicable OSHA lockout/tagout procedures. Do not exceed the torque capacity of the alloy steel fastener by using impact drivers without appropriate torque limiting.
