Value Collection 721097PR Flat Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 721097PR is a flat socket cap screw designed for fastening applications where a flush or countersunk installation is required. It features an 82-degree flat head with a 3/32-inch hex socket drive and a partially threaded shank. The fastener is machined from alloy steel and finished with black oxide for corrosion resistance in moderate environments. At 2-1/4 inches in overall length with an 8-32 UNC thread, it meets ASME/ANSI B18.3 and ASTM F835 standards. Licensed trades and maintenance professionals use this screw where a low-profile head is needed and socket-wrench access is limited to a hex key.

This flat socket cap screw is suited for use in mechanical assemblies, fixtures, enclosures, and machine components that require a flush-seated fastener. The 8-32 UNC thread is a standard coarse-thread designation commonly found in light mechanical and electrical enclosure applications. Its black oxide finish makes it appropriate for indoor and semi-protected environments where mild corrosion resistance is acceptable. The partial threading allows for clearance-hole engagement and precise clamping in two-piece assemblies.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 3/32-inch hex socket drive for use with a standard hex key or Allen wrench
• Alloy steel construction provides high tensile strength for its size class
• Black oxide finish offers mild corrosion resistance and low light reflection
• Partially threaded shank for clamping-force applications with clearance holes
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 8-32 UNC flat socket cap screw compatible with any countersunk hole machined to accept an 82-degree flat head per ASME/ANSI B18.3 specifications.

Installation Notes

Install using a 3/32-inch hex key or T-handle driver. Ensure the mating hole is properly countersunk to 82 degrees before installation to achieve full head seating. Do not overtighten, as alloy steel screws at this thread size can strip the socket drive or the mating thread if excessive torque is applied without reference to a proper torque specification for the assembly. Follow applicable mechanical codes and the equipment manufacturer guidelines for fastener torque requirements.
