Value Collection 721230PR Flat Socket Cap Screw 7/16-20

Product Description

The VALUE COLLECTION 721230PR is a flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies and structural connections. It features an 82-degree flat head profile and a 1/4-inch hex socket drive, accepting a standard hex key for installation and removal. The fastener is fully threaded at 7/16-20 UNF and measures 1-3/4 inches in overall length. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance in controlled environments. Licensed trades and industrial maintenance technicians working on machinery, fixtures, or fabricated assemblies commonly specify this screw type.

This screw is suited for applications where the fastener head must sit flush with or below the surface of the mating material. Common use cases include machine frames, tooling fixtures, precision assemblies, and equipment panels where a low-profile head is required. The UNF thread form provides fine thread engagement, making it appropriate where vibration resistance or precise torque control is needed. Sold individually with a minimum order quantity of five units.

Key Features

• 82-degree flat head profile for flush or countersunk seating
• 1/4-inch hex socket drive for standard hex key installation
• 7/16-20 UNF fully threaded shank for fine-thread engagement
• Alloy steel construction for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for assemblies requiring a countersunk hex socket cap screw with a 7/16-20 UNF thread and 1-3/4-inch overall length.

Installation Notes

Installation requires a correctly sized hex key or hex bit driver to avoid rounding the socket. Verify the mating material is pre-drilled and countersunk to the appropriate 82-degree angle before driving the fastener. Follow applicable torque specifications for the assembly grade and material being joined. Always de-energize or lock out equipment before servicing fastened assemblies on live machinery.
