Value Collection 30310 Hex Head Cap Screw 9/16-18 X 2.5 in

Product Description

The VALUE COLLECTION 30310 is a partially threaded hex head cap screw designed for fastening applications that require a controlled grip length. Made from Grade 5 steel with a zinc-plated finish, this fastener meets ASME B18.2.1 dimensional standards. The 9/16-18 UNF thread is a fine-pitch designation suited for joints where vibration resistance and precise torque control matter. At 2.5 inches under the head, the fastener provides a useful combination of shank length and thread engagement for medium-duty structural and mechanical assemblies. Sold in packages of 10.

This hex head cap screw is appropriate for general mechanical, structural, and equipment assembly work where inch-series UNF fasteners are specified. The Grade 5 rating indicates a medium-strength carbon steel fastener capable of handling moderate tensile loads. Zinc plating provides basic corrosion resistance for indoor and sheltered outdoor environments. Typical applications include machine frames, brackets, equipment housings, and utility connections across HVAC, plumbing, and electrical trade installations.

Key Features

• Grade 5 steel construction meets medium-strength fastener requirements for structural and mechanical use
• Zinc-plated finish provides baseline corrosion protection in sheltered environments
• 9/16-18 UNF fine-pitch thread delivers improved vibration resistance compared to coarse-pitch equivalents
• Partially threaded shank maintains a defined grip zone for joint clamping
• Conforms to ASME B18.2.1 dimensional standards for interchangeability and inspection compliance
• Packaged in quantities of 10 to support job-lot procurement

Compatibility

Designed as an OEM-style replacement or general-use fastener for any application specifying a 9/16-18 UNF partially threaded hex head cap screw per ASME B18.2.1.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for a 9/16-18 UNF fastener. Always verify that the mating threaded hole or nut matches the UNF thread standard before installation. Do not mix UNC and UNF hardware in the same joint. Torque to the specification listed in the equipment service documentation for Grade 5 fasteners of this diameter.
