National Mfg N232-942 Zinc J Bolt 3/8 X 3-3/4 in 10 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N232-942 is a zinc-plated J bolt measuring 3/8 inch in diameter and 3-3/4 inches in length. J bolts are threaded fasteners with a J-shaped hook end used to anchor structural components, pipe hangers, and equipment mounting brackets to concrete, wood, and masonry substrates. The zinc plating provides basic corrosion resistance for dry to moderately humid indoor environments. This part ships in bulk packaging with a quantity of 10 per unit. Plumbers, HVAC installers, and general contractors commonly use J bolts of this size for hanging pipe, securing equipment bases, and anchoring support structures during mechanical system installations.

This J bolt is suited for light commercial and residential mechanical installations where a 3/8 inch diameter threaded hook anchor is required. Typical applications include pipe hanger installations, conduit support anchoring, equipment pad tie-downs, and general structural fastening tasks. The 3-3/4 inch length accommodates standard embedment depths in wood framing or shallow concrete anchor applications. The bulk pack of 10 makes it practical for multi-point installations or stocking a service vehicle.

Installation Notes

J bolts of this type are typically installed by plumbers, HVAC technicians, or general contractors as part of pipe support or equipment anchoring work. Power down or de-energize any adjacent electrical systems before working in confined mechanical spaces. For concrete embedment, follow applicable building code requirements for anchor depth and edge distance. Do not overtighten nuts against hanger hardware, as this can deform the hook profile or strip the threads.
