Value Collection R52001348 Hex Head Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION R52001348 is a hex head cap screw designed for general-purpose fastening in industrial, mechanical, and structural applications. This fastener features a 1/2-13 UNC thread form and measures 14 inches in length under the head, making it suitable for through-bolting thicker assemblies. The screw is partially threaded, with a 3/4-inch hex drive. Constructed from Grade 2 steel with a zinc-plated finish, it provides a basic level of corrosion resistance for dry or mildly exposed environments. Installers and maintenance technicians working with standard bolted connections will find this a straightforward drop-in fastening solution.

This cap screw is appropriate for use in light to moderate structural connections, equipment mounting, and general mechanical assemblies where a partially threaded, coarse-thread fastener is specified. The 1/2-13 UNC thread is one of the most common coarse-thread profiles used in North American fabrication and maintenance work. The 14-inch shank length accommodates deep through-bolt applications. Sold individually per package, with a minimum order quantity of 10 pieces.

Key Features

• 1/2-13 UNC coarse thread form for broad compatibility with standard nuts and tapped holes
• 14-inch length under head for deep through-bolt and thick-stack applications
• Partially threaded shank provides a smooth bearing surface where full thread engagement is not required
• 3/4-inch hex drive for use with standard wrenches and sockets
• Grade 2 steel construction meets ASME B18.2.1 and SAE J429 standards
• Zinc-plated finish offers basic corrosion protection in dry or mildly exposed conditions

Compatibility

Designed as an OEM-style replacement or stock fastener for any application calling for a 1/2-13 UNC partially threaded hex head cap screw with a 14-inch length under head in Grade 2 steel.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or general tradespeople using a standard 3/4-inch open-end, box-end, or socket wrench. Always pair with a properly rated 1/2-13 UNC nut or tapped hole rated for Grade 2 fasteners. Verify that the zinc-plated finish is appropriate for the exposure environment before installation, as this finish is not recommended for immersed or highly corrosive conditions. Follow applicable torque tables from ASME or SAE references for 1/2-13 Grade 2 fasteners when precise clamp load is required.
