Value Collection 011499BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 011499BR is a hex socket cap screw designed for high-strength fastening in mechanical, industrial, and structural applications. It features a 7/8-9 UNC thread and measures 2.5 inches in length under the head, with full threading along the entire shank. The screw is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces surface reflectivity. Installation requires a 3/4-inch hex socket or hex key drive. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for load-bearing assemblies where dimensional and mechanical consistency are required.

This socket cap screw is suited for use in machinery, equipment fabrication, tooling fixtures, and general industrial assembly. The 7/8-9 UNC coarse thread pattern is common in heavy-duty fastening where quick assembly and resistance to cross-threading are priorities. The alloy steel construction and black oxide finish are standard in applications where high tensile strength is needed but full corrosion-proofing is not required. Typically installed by machinists, millwrights, and maintenance mechanics working on equipment and structural assemblies.

Key Features

• 7/8-9 UNC coarse thread for heavy-duty fastening applications
• 2.5-inch length under head with full threading along the entire shank
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion resistance and low-glare surface
• 3/4-inch hex socket drive for high torque installation
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 7/8-9 UNC hex socket cap screw per ASME/ANSI B18.3, suitable for use in any application requiring a fully threaded alloy steel socket cap screw of this thread size and length.

Installation Notes

Installation requires a calibrated torque wrench and a 3/4-inch hex key or socket drive. Ensure mating threads are clean and free of debris before installation. Do not use impact tools at final torque without a verified torque-limiting adapter. Follow applicable industry or equipment manufacturer torque specifications for 7/8-9 UNC alloy steel fasteners at the required preload.
