Value Collection -30165-8 Hex Cap Screw 7/8-9x8 Gr5 Zinc 10pk

Product Description

The VALUE COLLECTION -30165-8 is a partially threaded hex head cap screw designed for general mechanical and structural fastening applications. Built to Grade 5 steel with a zinc-plated finish, it meets ASME B18.2.1 and SAE J429 standards. The 7/8-9 thread size pairs with a unified national coarse (UNC) thread form, and the 8-inch length under head accommodates thick assemblies and through-bolt installations. This fastener is sold in a package quantity of 10 and is used by maintenance mechanics, millwrights, and contractors requiring reliable, code-compliant fasteners for mid-duty structural and equipment work.

This screw is suited for industrial maintenance, machine assembly, structural steel connections, and general construction applications where a partially threaded hex cap screw in a large diameter is required. The zinc plating provides moderate corrosion resistance for indoor and sheltered outdoor use. Each package contains 10 screws, making it practical for single-repair jobs or small batch installations without overbuying.

Key Features

• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish provides baseline corrosion resistance for general-purpose use
• Partially threaded shank allows clamping force without thread engagement through the full grip length
• 7/8-9 UNC thread is a widely used coarse-thread standard for high-load fastening
• Conforms to ASME B18.2.1 dimensional standards for hex cap screws
• Package of 10 units per purchase

Compatibility

Designed as a standard ASME B18.2.1 hex head cap screw for use in any application requiring a 7/8-9 UNC thread, 8-inch length under head, Grade 5 steel fastener.

Installation Notes

Installation is performed by maintenance mechanics, millwrights, or construction tradespeople using appropriate 7/8-9 hardware including nuts, washers, and tapped holes rated for Grade 5 fasteners. Verify hole clearance and thread engagement depth before installation. Apply thread lubricant or anti-seize only when specified by the equipment manufacturer or applicable structural specification. Consult applicable codes such as AISC or OSHA standards for torque and inspection requirements in structural applications.
