Value Collection 721314BR Flat Socket Cap Screw 7/8-9x6

Product Description

The VALUE COLLECTION 721314BR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 9/16-inch hex socket and is manufactured from alloy steel with a black oxide finish for corrosion resistance and reduced light reflection. The screw measures 7/8-9 thread size by 6 inches in overall length and is partially threaded, making it suited for through-bolt and heavy clamping applications. Machinists, millwrights, and industrial maintenance technicians commonly specify this fastener in structural assemblies, machine frames, and tooling fixtures where a recessed head is required.

This fastener is used in inch-system mechanical assemblies across manufacturing, fabrication, and maintenance environments. The UNC thread form provides reliable engagement in tapped steel and cast iron components. The partial threading allows the unthreaded shank to bear shear loads, which is advantageous in joint designs that require precise alignment or shear transfer between clamped members.

Key Features

• 82-degree flat head seats flush in standard countersunk holes per ASME/ANSI B18.3
• 9/16-inch hex socket drive for high torque input with standard hex keys or socket tooling
• Partially threaded shank supports shear-load applications and precise joint alignment
• Alloy steel construction provides high tensile and yield strength for demanding fastening tasks
• Black oxide finish reduces surface corrosion and minimizes light glare in tooling environments
• UNC thread form and ASME/ANSI B18.3 and ASTM F835 compliance ensure dimensional consistency

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 7/8-9 UNC tapped hole with an 82-degree countersunk seat, conforming to ASME/ANSI B18.3 and ASTM F835 dimensional standards.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 9/16-inch hex key or T-handle driver. Ensure the mating countersunk hole is machined to the correct 82-degree included angle before installation to achieve proper head seating. Torque to values appropriate for the alloy steel grade and joint material per applicable engineering specifications. De-energize and lock out any equipment before fastener replacement on live machinery.
