National Mfg N222-455 Stainless Steel U-bolt Marine Outdoor

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N222-455 is a stainless steel U-bolt designed for marine and other outdoor applications where corrosion resistance is a primary requirement. Measuring 5/16 inches in rod diameter with a 1-3/4-inch inside width and 4-1/4-inch leg length, this U-bolt is passivated to deliver superior surface protection against atmospheric corrosion. The non-magnetic stainless steel construction makes it well-suited for environments where standard zinc-plated or galvanized hardware would corrode prematurely. It is sold in bulk quantities of 5 units per package, making it practical for service trucks and job-site inventory.

This U-bolt is appropriate for securing pipe, conduit, tubing, or structural members in marine environments, coastal installations, dockside equipment, and general outdoor applications exposed to moisture, salt air, or weather. Its passivated finish provides an added layer of corrosion protection beyond standard stainless steel, making it a reliable choice for installations where hardware longevity in harsh conditions is critical. Plumbers, marine technicians, and general contractors working in corrosive outdoor environments will find this fitting practical for a wide range of fastening needs.

Installation Notes

Installation is typically performed by plumbers, marine technicians, or general contractors using standard hand tools. Before installation, ensure the mounting surface and mating hardware are clean and free of debris that could compromise the fastener seating. Use appropriately rated stainless steel nuts and washers to avoid galvanic incompatibility. Follow applicable local codes and manufacturer guidelines for fastener torque and load ratings.
