Value Collection 721182PR Flat Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION 721182PR is a flat socket cap screw designed for flush or countersunk fastening applications in precision assemblies. It features an 82-degree flat head profile and a 3/16-inch hex socket drive, accepting a standard hex key for installation and removal. The fastener is fully threaded along its 7/8-inch overall length and carries a 5/16-24 UNF thread form. Constructed from alloy steel with a black oxide finish, it provides solid mechanical strength and moderate corrosion resistance in controlled environments. Machinists, millwrights, and maintenance technicians are the typical installers for this fastener type.

This screw is suited for applications where the fastener head must sit flush with or below a mating surface. Common uses include machine frames, tooling fixtures, equipment panels, and precision mechanical assemblies where a protruding head would interfere with mating components or moving parts. The 5/16-24 UNF thread provides finer thread engagement than coarse-thread equivalents, making it a preferred choice in applications requiring stronger clamp load or vibration resistance in thinner or harder materials.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 3/16-inch hex socket drive for precise torque application with a standard hex key
• 5/16-24 UNF fully threaded for maximum thread engagement over full length
• Alloy steel construction for high tensile strength under mechanical load
• 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 standard-fit fastener for any assembly requiring a 5/16-24 UNF flat socket cap screw with an 82-degree countersunk head per ASME/ANSI B18.3 and ASTM F835 specifications.

Installation Notes

Installation is performed using a 3/16-inch hex key or hex bit driver. Ensure the receiving hole is properly countersunk to 82 degrees for full head seating before driving the fastener. De-energize or lock out any equipment before servicing assemblies that include this fastener. Follow applicable torque guidelines for 5/16-24 alloy steel fasteners as specified by the equipment manufacturer or relevant industry standards.
