Value Collection MP30165-3 Hex Head Cap Screw 7/8-9

Product Description

The Value Collection MP30165-3 is a Grade 5 steel hex head cap screw sized 7/8-9 UNC by 3 inches under the head. It is partially threaded and finished with a zinc-plated coating for corrosion resistance in general-purpose fastening applications. This screw conforms to ASME B18.2.1, the standard governing inch-series hex head cap screws, ensuring dimensional consistency for use in structural assemblies, machinery, and mechanical equipment. It is a standard inch-measurement fastener suitable for mechanical contractors, millwrights, equipment technicians, and maintenance professionals working with bolted connections in trade and industrial environments.

This fastener is suited for a wide range of mechanical and structural applications where a 7/8-9 UNC partially threaded hex cap screw is required. Typical use cases include bolted steel-to-steel connections, equipment mounting, and heavy mechanical assemblies in commercial and industrial settings. The partial threading allows a shank section to pass through clearance holes while providing full thread engagement at the nut or tapped hole. Sold in packages of 10 per order.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians following applicable torque guidelines for Grade 5 fasteners per the relevant equipment or structural specification. Always de-energize and lock out equipment before servicing bolted assemblies. Use a properly sized hex socket or open-end wrench to avoid fastener damage. Verify thread engagement depth and clearance hole sizing before installation.
