Value Collection 011497BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 011497BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 7/8-9 UNC thread specification and measures 2-1/4 inches in length under the head with full threading from end to head. The fastener is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces surface reflectivity. The 3/4-inch hex drive accepts a standard hex key or socket drive tool. This screw is suited for machinists, millwrights, maintenance technicians, and mechanical contractors working on equipment assembly or repair.

This screw is used wherever a flush or recessed fastener head is required in a threaded bore or clearance hole application. Common installations include machine bases, jigs, fixtures, brackets, and mechanical equipment frames. The 7/8-9 UNC coarse thread profile provides good thread engagement and ease of assembly in steel and cast iron components. It is appropriate for both light industrial and heavy equipment applications where a socket-drive cap screw is specified.

Key Features

• 7/8-9 UNC coarse thread for reliable engagement in steel and cast iron
• Fully threaded shank — 2-1/4 inches length under head
• 3/4-inch hex socket drive for use with standard hex keys or socket drivers
• Alloy steel construction for high tensile strength
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-specification hex socket cap screw for mechanical assemblies requiring a 7/8-9 UNC fully threaded fastener conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance mechanics using a calibrated torque wrench with a 3/4-inch hex bit or hex key. Always power down and de-energize or de-pressurize any equipment before replacing or installing structural fasteners. Do not install into damaged or cross-threaded bores. Follow equipment manufacturer torque specifications and applicable codes for the assembly being serviced.
