Value Collection D30120 Hex Head Cap Screw 1/2-13x6 Grade 5

Product Description

The VALUE COLLECTION D30120 is a partially threaded hex head cap screw sized 1/2-13 x 6 inches, manufactured from Grade 5 steel with a zinc-plated finish. It conforms to ASME B18.2.1 standards for inch-series hex cap screws. The 1/2-13 designation indicates a 1/2-inch nominal diameter with 13 threads per inch on a UNC thread form. The partial threading leaves a smooth shank under the head, which is suited for applications requiring a grip length or clearance fit through one or more members before engaging the threaded portion. Installers in mechanical, HVAC, plumbing, and general industrial trades use fasteners of this type for structural and equipment-mounting connections.

This fastener is appropriate for general mechanical assembly, equipment mounting, and structural connections in both residential and commercial trade applications. The zinc plating provides a baseline level of corrosion resistance suitable for indoor and moderately protected outdoor environments. The 6-inch length under head accommodates thicker assemblies or stacked components where shorter fasteners would not achieve adequate thread engagement. A standard hex drive accepts common wrenches and sockets found in any trade toolkit.

Key Features

• 1/2-13 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• Grade 5 steel construction provides higher tensile strength than Grade 2 hardware
• Zinc-plated finish for baseline corrosion resistance in protected environments
• Partially threaded shank allows grip-length clearance through clamped members
• Conforms to ASME B18.2.1 for dimensional consistency and interchangeability
• Hex head drive accepts standard open-end, box, and socket wrenches

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, flat washers, and lock washers in inch-series mechanical assemblies conforming to ASME or equivalent standards.

Installation Notes

Installation is performed by qualified mechanics, HVAC technicians, or plumbers as part of equipment assembly or structural fastening work. De-energize and lock out all equipment before disassembly or fastener replacement in any powered system. Use the correct wrench or socket size to avoid rounding the hex head, and ensure the mating nut or tapped hole is clean and free of debris before engagement. Do not exceed the rated torque for Grade 5 hardware as specified in applicable mechanical or equipment codes.
