Value Collection R52001273 Hex Head Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION R52001273 is a 3/4-10 UNC hex head cap screw designed for general-purpose fastening in structural, mechanical, and industrial applications. The fastener is partially threaded with a 7.5-inch length under head and a 1.125-inch hex drive. Constructed from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this screw conforms to ASME B18.2.1 and SAE J429 standards. It is a straightforward, utility-grade fastener suited for assembly work, equipment mounting, and structural connections where Grade 2 specifications are acceptable.

This cap screw is used across a wide range of trade applications including HVAC equipment mounting, plumbing support structures, electrical panel frames, and general mechanical assembly. The partial thread design allows the unthreaded shank to bear shear loads, making it appropriate for bolted connections where shear strength matters. It is well suited for both shop fabrication and field installation by maintenance technicians, millwrights, and service professionals working with standard hardware.

Key Features

• 3/4-10 UNC thread form for compatibility with standard unified coarse-thread nuts and tapped holes
• 7.5-inch length under head — partially threaded for shear load capacity at the shank
• 1.125-inch hex drive head for use with standard hex wrenches and sockets
• Grade 2 steel construction meeting SAE J429 requirements
• Zinc-plated finish for basic corrosion and oxidation resistance in dry or mildly humid environments
• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard 3/4-10 UNC Grade 2 hex head cap screw compatible with any application requiring an ASME B18.2.1-conforming fastener of this thread size and length.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or trade professionals using a standard hex socket or open-end wrench sized for a 1.125-inch hex head. Always verify the mating nut or tapped hole is rated for Grade 2 hardware before installation. De-energize or shut down any equipment before fastening components in live mechanical or electrical systems. Do not use Grade 2 fasteners as substitutes where Grade 5 or Grade 8 specifications are required by the equipment manufacturer or applicable codes.
