Value Collection R52001346 Hex Head Cap Screw

Product Description

The VALUE COLLECTION R52001346 is a 1/2-13 UNC hex head cap screw designed for general fastening applications in mechanical, structural, and industrial assembly work. The screw is partially threaded with a 3/4-inch hex drive and measures 8.5 inches in length under the head. It is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance. This fastener meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards. It is a standard choice for maintenance technicians, contractors, and fabricators who need a reliable UNC-thread cap screw in a longer shank length.

This cap screw is suited for residential, commercial, and light industrial applications where 1/2-13 UNC threading is specified. The partial thread and extended 8.5-inch shank make it appropriate for bolting through thick material stacks or for applications that require a grip length beyond what a fully threaded fastener can provide. Typical uses include equipment mounting, structural framing connections, and general mechanical assembly where Grade 2 steel tensile properties are acceptable.

Key Features

• 1/2-13 UNC thread form for compatibility with standard UNC nuts and tapped holes
• Partially threaded shank at 8.5 inches length under head for extended grip length applications
• Grade 2 steel construction meeting SAE J429 mechanical requirements
• Zinc-plated finish for basic corrosion protection in dry or mildly humid environments
• 3/4-inch hex head drive compatible with standard sockets and wrenches
• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw for use with any UNC-compatible nut, washer, or tapped hole of the same thread designation.

Installation Notes

Installation is typically performed by maintenance technicians, millwrights, or contractors using a 3/4-inch socket or combination wrench. Always verify that the mating nut or tapped hole matches the 1/2-13 UNC thread specification before installation. Apply appropriate torque per the project engineering specification for Grade 2 fasteners. Do not exceed the rated mechanical limits of Grade 2 steel in high-load or vibration-critical joints where a higher grade fastener may be required.
