National Mfg N222-448 Stainless Steel U-bolt Marine Outdoor

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N222-448 is a stainless steel U-bolt designed for marine and outdoor fastening applications. Measuring 5/16 inches in diameter with a 1-3/8 inch inside width and 2-1/2 inch leg length, this Series 512 U-bolt is passivated for superior corrosion resistance and is non-magnetic, making it well suited for saltwater and high-humidity environments. It is sold in bulk packs of 5 units per package and is ready for immediate field use by marine technicians, riggers, and general contractors working in corrosive outdoor conditions.

This U-bolt is intended for marine hardware installations and other outdoor applications where atmospheric corrosion is a primary concern. Typical uses include securing pipes, cables, rods, or structural members in boat, dock, and outdoor utility installations. The passivated stainless steel construction meets the demands of repeated exposure to moisture, salt air, and weather without surface degradation. It is appropriate for both residential marine use and light commercial outdoor fastening work.

Installation Notes

Installation is typically performed by marine technicians, riggers, or general contractors using standard hand tools. Always ensure the mounting surface and mating hardware are compatible with stainless steel to avoid galvanic corrosion. Tighten fasteners to the structural requirements of the application without over-torquing, which can stress the U-bolt legs. Follow applicable marine or building codes for fastener selection and load ratings in the specific installation environment.
