Value Collection -30165-5 Hex Cap Screw 7/8-9 X 5 in Grade 5

Product Description

The VALUE COLLECTION -30165-5 is a partially threaded hex head cap screw designed for industrial and mechanical fastening applications. It carries a 7/8-9 UNC thread size with a 5-inch length under head, manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. Conforming to ASME B18.2.1, this fastener meets standardized dimensional tolerances expected in structural and machine assembly work. The partial threading allows for a smooth shank section, which is appropriate for applications requiring bolt stretch or precise shear loading. Packaged in quantities of 25, this screw suits both job-site use and shop stock replenishment.

This hex head cap screw is suited for general mechanical assembly, structural connections, and equipment fabrication across industrial, construction, and maintenance trades. The 7/8-9 UNC thread is a common heavy-duty fastener size found in steel framing, machinery mounting, and equipment installation. The zinc-plated finish provides light corrosion protection appropriate for indoor or sheltered applications. Mechanics, millwrights, ironworkers, and maintenance technicians working on steel assemblies will encounter this fastener size regularly in field and shop environments.

Key Features

• 7/8-9 UNC thread with 5-inch length under head for heavy-duty fastening depth
• Grade 5 steel construction meets minimum tensile and proof load requirements for structural fastener applications
• Partially threaded shank provides a smooth bearing section for shear-critical connections
• Zinc-plated finish offers light corrosion resistance for general indoor and sheltered use
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws
• Sold in a 25-piece package for efficient stocking and job-site use

Compatibility

Designed as a standard inch-series hex head cap screw conforming to ASME B18.2.1, suitable for use with standard 7/8-9 UNC threaded nuts, tapped holes, and hardware compliant with that thread specification.

Installation Notes

Installation is performed by mechanics, millwrights, or ironworkers using standard hex wrenches or impact tooling sized for a 7/8-inch hex head. Always verify thread engagement depth and hole cleanliness before driving the fastener. Follow applicable torque specifications from the equipment OEM or structural engineer of record, as this prompt does not supply torque values. Refer to ASME or applicable job specifications for minimum thread engagement requirements when installing into tapped steel.
