Value Collection R52001210 Hex Head Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION R52001210 is a partially threaded hex head cap screw designed for general fastening applications in structural, mechanical, and industrial assemblies. It features a 1/2-13 UNC thread form and a 12-inch length under the head, making it suited for through-bolting or deep-fastening scenarios where a full-thread grip is not required. Manufactured from Grade 2 steel with a zinc-plated finish, it provides basic corrosion resistance for typical shop and field use. The 3/4-inch hex head allows installation with standard wrenches or impact drivers. Machinists, maintenance technicians, and tradespeople working with structural steel, equipment frames, or machinery mounting applications will find this fastener a straightforward fit.

This cap screw is commonly used in light to medium structural connections, equipment mounting, and general fabrication where a coarse-thread, partially threaded fastener is specified. The 1/2-13 UNC coarse thread is a widely adopted standard in North American mechanical and industrial assemblies. Zinc plating offers mild corrosion protection suitable for indoor or sheltered environments. Applications span HVAC equipment mounting, electrical panel framing, plumbing support structures, and general MRO work.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard nuts and tapped holes
• 12-inch length under the head accommodates deep through-bolt applications
• Partially threaded shank provides a smooth bearing surface in the grip zone
• Grade 2 steel construction meets ASME B18.2.1 and SAE J429 standards
• Zinc-plated finish offers basic corrosion resistance for general-use environments
• 3/4-inch hex head compatible with standard wrenches and impact sockets

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw per ASME B18.2.1, compatible with any 1/2-13 UNC threaded nut, coupling nut, or tapped hole conforming to that standard.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or tradespeople using a standard 3/4-inch wrench or impact socket. Always ensure mating threads are clean and free of debris before assembly. Do not use in applications requiring Grade 5 or Grade 8 rated fasteners without verifying load requirements against applicable standards. Follow torque specifications outlined in the relevant mechanical or structural code for the assembly being serviced.
