Value Collection D30108 Hex Head Cap Screw 1/2-13 X 2 in

Product Description

The VALUE COLLECTION D30108 is a 1/2-13 UNC hex head cap screw made from Grade 5 steel with a zinc-plated finish. It measures 2 inches under the head and features partial threading, conforming to ASME B18.2.1 dimensional standards. This fastener is a standard inch-series hex cap screw suited for general mechanical assembly, structural connections, and equipment fabrication. Installation is performed by maintenance technicians, millwrights, and general tradespeople using a standard hex wrench or socket driver. The zinc plating provides a baseline level of corrosion resistance for indoor and light-duty outdoor applications.

This screw is appropriate for use in general industrial, commercial, and trade applications where a Grade 5 steel fastener with UNC threading is specified. Partial threading along the shank allows for a bearing surface in through-bolt and clamped-joint applications. It fits standard 1/2-13 tapped holes and is compatible with matching hex nuts and washers in inch-series hardware assemblies.

Key Features

• 1/2-13 UNC thread form for compatibility with standard inch-series tapped holes and nuts
• 2-inch length under head for adequate grip in medium-thickness material stacks
• Grade 5 steel construction meets tensile strength requirements for general structural fastening
• Zinc-plated finish provides corrosion resistance in indoor and light-duty environments
• Partial threading preserves a smooth shank section for shear-bearing and clamped-joint use
• Conforms to ASME B18.2.1 for dimensional consistency across assemblies

Compatibility

Designed as an OEM-style replacement or standard-stock hex cap screw for any application specifying a 1/2-13 UNC x 2-inch Grade 5 partially threaded fastener per ASME B18.2.1.

Installation Notes

Installation is typically performed by a licensed mechanic, millwright, or qualified tradesperson using a standard socket or wrench sized for a 1/2-inch hex cap screw. Always verify thread engagement depth and torque specifications against the equipment manufacturer's service documentation before final tightening. Do not mix inch-series and metric fasteners in the same joint assembly. Inspect the mating tapped hole or nut for thread damage before installation.
