Value Collection 721300BR Flat Socket Cap Screw 7/8-9x2in

Product Description

The VALUE COLLECTION 721300BR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Sized at 7/8-9 thread and 2 inches in overall length, this screw is fully threaded and features an 82-degree flat head driven by a 9/16-inch hex socket. The body is machined from alloy steel and finished with black oxide for basic corrosion resistance and reduced light reflection. It conforms to ASME/ANSI B18.3 and ASTM F835 standards. Installation requires a hex key or socket driver sized to 9/16 inch.

This flat socket cap screw is suited for industrial, mechanical, and structural assemblies where the fastener head must sit flush with or below the mating surface. Typical applications include machine frames, fixtures, tooling plates, and equipment panels. The UNC thread form makes it compatible with standard inch-series tapped holes. It is installed by machinists, millwrights, maintenance technicians, and mechanical contractors working on machinery and fabricated assemblies.

Key Features

• 82-degree flat head profile for flush and countersunk installations
• 9/16-inch hex socket drive for positive torque transfer
• Fully threaded 7/8-9 UNC thread form for maximum thread engagement
• Alloy steel construction for high tensile strength
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard-dimension replacement or new-installation fastener for any application requiring a 7/8-9 UNC fully threaded flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835 specifications.

Installation Notes

Install using a calibrated torque wrench with a 9/16-inch hex key or socket bit appropriate for the alloy steel grade. Ensure the mating hole is properly countersunk to 82 degrees before installation to achieve a flush seating surface. De-energize and lock out any equipment before fastener removal or replacement in live machinery. Follow applicable mechanical and structural codes for fastener torque and joint requirements.
