Value Collection 011501BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 011501BR is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a clean appearance suited to close-tolerance environments. It carries a 7/8-9 UNC thread size and measures 2.75 inches in length under the head, with full threading along the shank. The 3/4 inch hex drive accepts standard hex keys and Allen wrenches. This screw conforms to ASME/ANSI B18.3 and ASTM A574, meeting the mechanical strength requirements expected in demanding trade and manufacturing environments.

This cap screw is used in general mechanical assembly, machine building, tooling fixtures, and maintenance repair operations where a flush or recessed fastener head is required. The fully threaded shank provides maximum thread engagement in blind holes and through-hole applications. It is commonly installed by machinists, millwrights, maintenance technicians, and industrial assembly personnel working with steel or heavy fabrications.

Key Features

• 7/8-9 UNC thread for wide compatibility with standard inch-series tapped holes
• 2.75 inches length under head provides substantial thread engagement depth
• Fully threaded shank maximizes clamping force in through-hole and shallow blind-hole applications
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides moderate corrosion resistance and reduces light reflection
• 3/4 inch hex drive accepts standard hex keys for installation in confined spaces

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any 7/8-9 UNC tapped hole requiring a high-strength alloy steel fastener with a recessed hex drive.

Installation Notes

Install using a 3/4 inch hex key or Allen wrench; ensure the mating tapped hole is clean and free of debris before installation. Power down or de-energize any equipment before performing fastener work on live assemblies. Do not exceed the rated mechanical load for the ASTM A574 grade; consult engineering specifications for joint design and torque requirements. Follow applicable ASME or facility maintenance codes when used in structural or pressure-retaining assemblies.
