Value Collection 721224PR Flat Socket Cap Screw 7/16-14

Product Description

The VALUE COLLECTION 721224PR is a flat socket cap screw designed for applications where a flush or countersunk fastener head is required. It features an 82-degree flat head with a 1/4-inch hex socket drive and a 7/16-14 UNC thread over a 2-1/4-inch overall length. The screw is fully threaded and manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection. This fastener meets ASME/ANSI B18.3 and ASTM F835 standards, making it appropriate for structural and mechanical assemblies where dimensional consistency and material strength matter.

This flat socket cap screw suits residential and commercial mechanical, industrial, and fabrication applications where a recessed drive and countersunk profile are needed. Typical install scenarios include machine housings, fixture mounting, tooling plates, and assemblies where the fastener head must sit flush or below the work surface. Licensed tradespeople and experienced fabricators working with ferrous and structural components will find this screw compatible with standard hex key tooling.

Key Features

• 82-degree flat head profile allows flush or countersunk installation
• 1/4-inch hex socket drive for use with standard hex keys or Allen wrenches
• Fully threaded 7/16-14 UNC shank over 2-1/4-inch overall length
• Alloy steel construction for high tensile strength in load-bearing fastener applications
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard 7/16-14 UNC threaded holes requiring a countersunk flat-head socket fastener per ASME/ANSI B18.3 dimensional specifications.

Installation Notes

Installation requires a properly sized countersunk hole to accept the 82-degree flat head profile; verify countersink angle and diameter before installation. Use a calibrated hex key or socket driver sized to 1/4 inch to avoid rounding the drive recess. Ensure mating threads are clean and undamaged before fastening. Follow applicable torque guidelines for 7/16-14 alloy steel fasteners per the assembly specification or relevant industry standard.
