National Mfg N245-027 Square U Bolt 3/8x3-5/8x7 Zinc 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N245-027 is a zinc-plated square U bolt sized at 3/8 x 3-5/8 x 7 inches, supplied with plate and hex nuts attached. It is designed for lumber-size applications where a fastener must secure components to rectangular wood or metal objects. The square bend profile distributes clamping load evenly across flat surfaces, making it well suited for structural fastening tasks on jobsites, in mechanical rooms, or in utility installations. Each package contains 5 bolts with hardware included, reducing the need for separately sourced plate and nut components. Plumbers, electricians, HVAC technicians, and general contractors all reach for this type of hardware when anchoring pipe hangers, conduit supports, or equipment frames to structural members.

This U bolt fits lumber-size applications and is intended for use on rectangular wood or metal objects. The included plate and hex nuts allow for a complete installation without additional hardware sourcing. Typical install scenarios include securing pipe runs, conduit bundles, equipment mounting brackets, or structural supports to wood beams or metal framing members in residential and light commercial settings. Each unit is sold in a boxed loose pack of 5.

Installation Notes

Installation is typically performed by a licensed tradesperson or qualified installer following applicable local building codes. Shut off or de-energize any associated systems before fastening hardware near electrical or mechanical equipment. Tighten hex nuts evenly and in alternating passes to maintain even clamping pressure across the plate. Do not overtighten on wood members, as this can compress or split the substrate.
