Value Collection 721064PR Flat Socket Cap Screw 6-32

Product Description

The VALUE COLLECTION 721064PR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Sized at 6-32 x 5/16 inches overall length with full UNC threading, this screw features an 82-degree flat head driven by a 5/64-inch hex socket. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and clean aesthetics in assemblies where a protruding head is not acceptable. This fastener meets ASME/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and precision assembly technicians regularly specify this style in panel, fixture, and machine-frame applications.

The 721064PR suits both light industrial and precision mechanical assembly work. Its 82-degree countersunk head seats flush in standard countersunk holes drilled and chamfered to match the head angle. Fully threaded along its 5/16-inch length, it provides maximum thread engagement in thin stock and shallow-depth bosses. Typical use cases include enclosure panels, jig and fixture construction, and instrument assemblies where a low-profile fastened joint is required.

Key Features

• 82-degree flat countersunk head sits flush with or below the mating surface
• 5/64-inch hex socket drive for precise torque application with standard hex keys or allen drivers
• Fully threaded 6-32 UNC shank maximizes thread engagement in shallow stock
• Alloy steel construction provides high tensile strength relative to standard carbon steel fasteners
• Black oxide finish offers moderate corrosion resistance and reduces light reflection in finished assemblies
• Meets ASME/ANSI B18.3 and ASTM F835 dimensional and mechanical standards

Compatibility

Designed as a standard 6-32 UNC flat socket cap screw compatible with any countersunk clearance hole machined to accept an 82-degree head per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is performed by machinists or assembly technicians using a 5/64-inch hex key or socket driver. The mating hole must be countersunk to 82 degrees at the correct diameter for the screw head to seat flush. Apply appropriate thread-locking compound if vibration is a concern in the application. De-energize and lock out any equipment before replacing or adjusting fasteners on powered assemblies.
