Value Collection 721234PR Flat Socket Cap Screw 7/16-20

Product Description

The VALUE COLLECTION 721234PR is a flat socket cap screw engineered for applications requiring a flush or countersunk fastener profile. Sized at 7/16-20 x 2-1/2 inches overall length, it features an 82-degree flat head with a 1/4-inch hex socket drive. The alloy steel construction and black oxide finish provide corrosion resistance and surface hardness suited to demanding mechanical assemblies. Threading is partial and conforms to Unified National Fine (UNF) standards. Fastener geometry meets ASME/ANSI B18.3 and ASTM F835 specifications, making it a reliable choice for precision mechanical, industrial, and maintenance applications.

This screw is used wherever a low-profile countersunk fastener is needed and clearance above the joint surface is limited. Typical applications include machine assemblies, fixtures, tooling plates, and structural components where a flush finish is required. The partially threaded shank provides a smooth bearing surface through the clearance hole, helping to locate and clamp mating parts accurately. Suitable for industrial, manufacturing, and trade maintenance environments.

Key Features

• 82-degree flat head profile for flush or countersunk installations
• 1/4-inch hex socket drive for high torque input with a standard Allen key or hex bit
• 7/16-20 UNF thread for fine-pitch clamping precision
• Partially threaded shank for accurate part location through clearance holes
• Alloy steel construction with black oxide finish for corrosion and wear resistance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNF flat socket cap screw for use in any tapped 7/16-20 threaded hole requiring an 82-degree countersunk flat-head fastener per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 1/4-inch hex key or socket bit driver. Ensure the mating countersink is machined to an 82-degree included angle to achieve full head seating. Power down and de-energize any equipment before servicing fastened assemblies. Do not exceed the rated torque range for alloy steel fasteners of this thread size as specified by the applicable mechanical or equipment standard.
