Value Collection 721214PR Flat Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION 721214PR is a flat socket cap screw designed for flush or countersunk fastening applications in metalworking, machinery, and structural assemblies. It features an 82-degree flat head profile and a 7/32-inch hex socket drive, allowing installation with a standard hex key. Manufactured from alloy steel with a black oxide finish, it provides solid corrosion resistance in moderate-duty environments. The 3/8-24 UNF thread is fully threaded along the 7/8-inch overall length, ensuring consistent engagement through thinner material sections. Licensed trades and machine shop professionals install this type of fastener where a low-profile head is required to sit flush with or below the mating surface.

This screw is suited for precision mechanical assemblies, jigs, fixtures, tooling plates, and equipment housings where a protruding head is not acceptable. The UNF thread pitch provides finer thread engagement compared to UNC, making it appropriate for high-strength joints, vibration-prone assemblies, and applications requiring precise torque control. It is commonly used in industrial maintenance, OEM equipment manufacturing, and general machining environments where alloy steel strength is needed.

Key Features

• 82-degree flat head profile seats flush or countersunk in mating material
• 7/32-inch hex socket drive compatible with standard hex keys and Allen drivers
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Black oxide finish offers moderate corrosion resistance and reduces light reflection
• Fully threaded 7/8-inch overall length maximizes thread engagement through thin sections
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style and MRO replacement flat socket cap screw for machinery, fixtures, and equipment requiring a 3/8-24 UNF fully threaded flat-head fastener with an 82-degree countersink angle.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 7/32-inch hex key or Allen driver. The mating hole must be properly countersunk to 82 degrees to allow the flat head to seat correctly. De-energize and lock out any powered equipment before performing fastener replacement or installation. Do not exceed the rated torque specifications published in ASME B18.3 for the applicable alloy steel grade.
