National Marker N245001 Zinc Square U Bolt 3/8x3-5/8x5

Product Description

The NATIONAL MARKER N245001 is a zinc-plated square U bolt designed for securing components to rectangular wood and metal surfaces. Manufactured from steel wire with a zinc finish, this fastener measures 3/8 inches in rod diameter, 3-5/8 inches in width, and 5 inches in length. Each unit ships fully assembled and includes a mounting plate and two hex nuts, making it ready for immediate installation. At 0.534 pounds, it is a compact, duty-rated fastener suited for trade and industrial applications where a square-profile U bolt is required over a standard round-bend style.

This U bolt is appropriate for use in plumbing, HVAC, electrical, and general mechanical installations where straps or brackets need to secure conduit, pipe, or structural members to rectangular wood beams or metal channels. The square bend profile provides flat, parallel legs that seat evenly against the mounting surface, improving load distribution compared to round-bend alternatives. The included plate and hex nuts allow immediate assembly without sourcing additional hardware. Installers working on pipe hangers, equipment supports, or conduit strapping will find this fastener a direct fit for rectangular-section applications.

Compatibility

Designed as an OEM-style replacement or standard installation fastener for securing pipe, conduit, or structural members to rectangular wood and metal objects in residential and light commercial applications.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with mechanical fastener and pipe support requirements applicable to the specific trade. Ensure the mounting surface is structurally sound before tightening the hex nuts. Consult applicable codes such as the IPC or NEC for minimum support spacing and fastener requirements for the specific pipe or conduit type being secured. Do not overtighten the hex nuts, as excessive torque can deform the U bolt legs or damage the secured component.
