Value Collection R52001156 Hex Head Bolt 3/8-16 7in Grade 2

Product Description

The VALUE COLLECTION R52001156 is a Grade 2 steel hex head bolt with a 3/8-16 UNC thread and a 7-inch length under head. It features a hot-dipped galvanized finish for corrosion resistance in exposed or outdoor installations. The bolt is partially threaded and accepts a 9/16-inch hex wrench or socket. It conforms to ANSI/ASME B18.2.1 dimensional standards. This fastener is suited for general structural and mechanical assembly work across plumbing, HVAC, electrical, and related mechanical trades where a standard inch-system hex bolt is required.

This bolt is appropriate for residential and light commercial construction and equipment assembly applications. Partially threaded shanks provide clamping strength in through-bolt applications where thread engagement is needed only at the nut end. The hot-dipped galvanized coating makes it a practical choice for outdoor, wet, or mildly corrosive environments such as equipment pads, rooftop HVAC installations, utility brackets, and pipe hangers. Trade installers in HVAC, plumbing, and electrical work commonly use fasteners of this type when securing equipment to structural members or mounting hardware to concrete and steel substrates.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard inch-system nuts and tapped hardware
• 7-inch length under head provides reach for thick structural assemblies or stacked components
• Hot-dipped galvanized finish delivers corrosion resistance in outdoor and wet service environments
• Partially threaded shank maintains shear strength while providing secure nut engagement
• Conforms to ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional and fastener standards
• Grade 2 steel construction suited for general-purpose mechanical and structural fastening

Compatibility

Designed as a general-purpose replacement or stocking fastener compatible with any standard 3/8-16 UNC threaded hex nut or tapped hole conforming to ANSI/ASME inch-series fastener standards.

Installation Notes

Install and torque with a 9/16-inch wrench or socket driver. Always power down or de-energize equipment before fastening components in electrical or HVAC assemblies. Use appropriate washers and hardware rated for the load and environment. Follow applicable mechanical and structural codes for fastener torque and spacing requirements specific to the installation.
