Value Collection 307208BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 307208BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Built from alloy steel with a black oxide coating, this fastener meets ASTM A574 specifications, which govern mechanical properties for socket cap screws. It accepts a 9/16 inch hex key drive and provides reliable torque transfer in confined spaces where standard hex head tools cannot reach. Licensed trades and industrial maintenance technicians commonly specify this screw type for machinery, fixtures, and equipment enclosures requiring a flush or recessed fastener profile.

This screw is suited for use in ferrous metal assemblies, mechanical fixtures, jigs, and production equipment. The 7/8-9 UNC thread series is a coarse thread pattern commonly found in general industrial and manufacturing applications. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision equipment environments. Partial threading allows for stronger clamping force in non-through-hole applications where the unthreaded shank bears shear loads.

Key Features

• ASTM A574 compliant alloy steel construction for high tensile strength
• Black oxide coating provides mild corrosion resistance and a non-reflective finish
• Partially threaded shank supports shear load applications
• 9/16 inch hex socket drive for use with standard hex keys or socket drivers
• 7/8-9 UNC coarse thread for broad compatibility with standard tapped holes
• 2.5 inch length under head suits medium-depth clamping applications

Compatibility

Designed as an OEM-style replacement or standard fastener for industrial and mechanical assemblies using 7/8-9 UNC tapped holes requiring a socket cap screw with 2.5 inch length under head.

Installation Notes

Installation should be performed by qualified mechanics or maintenance technicians using the appropriate 9/16 inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before threading the screw. De-energize and lock out all equipment before replacing or installing fasteners in live machinery, following applicable OSHA lockout/tagout procedures. Do not use impact tools at full torque without confirming the fastener and hole thread integrity.
