Value Collection 721227PR Flat Socket Cap Screw 7/16-20

Product Description

The VALUE COLLECTION 721227PR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head with a hex socket drive and is fully threaded along its 1-inch length on a 7/16-20 UNF thread. Manufactured from alloy steel with a black oxide finish, it delivers solid corrosion resistance and wear performance in mechanical assemblies. This fastener is installed using a 1/4-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and mechanical contractors use this type of fastener where a low-profile head is required to sit flush with or below a mating surface.

This flat socket cap screw is suited for use in precision mechanical assemblies, machine frames, fixtures, and equipment where clearance above the fastener is limited. The 7/16-20 UNF fine thread provides strong clamping force and resistance to vibration loosening, making it appropriate for dynamic or load-bearing connections. The black oxide finish is compatible with oiled or dry service environments common in industrial and trade settings.

Key Features

• 82-degree flat head profile allows flush or countersunk installation
• Hex socket drive accepts a 1/4-inch hex key for precise torque application
• 7/16-20 UNF fully threaded, 1-inch length
• Alloy steel construction for high tensile strength
• Black oxide finish for basic corrosion and wear resistance
• Meets ASME/ANSI B18.3 and ASTM F835 standards

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 7/16-20 UNF fully threaded fastener with an 82-degree countersunk flat head.

Installation Notes

Installation is performed using a 1/4-inch hex key or socket driver. Countersink the mating surface to match the 82-degree head angle before installation to ensure full head seating. Follow applicable torque guidelines for alloy steel fasteners of this thread class per your assembly specification. Verify thread engagement depth meets design requirements before applying load.
