National Mfg N222-430 Stainless Steel U-bolt Marine Outdoor

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N222-430 is a stainless steel U-bolt designed for marine and outdoor fastening applications. Measuring 1/4 inch rod diameter by 1-1/8 inches inside width by 3-1/2 inches inside length, this Type 316-grade-class U-bolt is passivated after manufacturing to enhance surface corrosion resistance beyond the base alloy. The stainless steel construction is non-magnetic, making it suitable for installations where magnetic interference is a concern. This hardware is sold in a bulk pack of 5 pieces per package and is intended for use by marine technicians, riggers, and outdoor equipment installers working in corrosive environments.

This U-bolt is suited for marine deck hardware, rigging, pipe and conduit support, antenna mounts, and general outdoor structural fastening where atmospheric corrosion resistance is required. The passivated finish provides superior resistance to salt air, moisture, and oxidation compared to standard stainless steel hardware. It is appropriate for both residential marine applications and light commercial outdoor installations where a non-magnetic, corrosion-resistant fastener is specified.

• Rod diameter: 1/4 inch; inside width: 1-1/8 inches; inside length: 3-1/2 inches
• Sold in a bulk pack of 5 pieces per package

Compatibility

Designed for marine and outdoor applications requiring a corrosion-resistant, non-magnetic U-bolt fastener in a 1/4 inch by 1-1/8 inch by 3-1/2 inch configuration.

Installation Notes

Installation should be performed by a qualified marine technician, rigger, or experienced installer familiar with fastener torque and load requirements for the specific application. Ensure mating hardware such as nuts, washers, and backing plates are also stainless steel to prevent galvanic corrosion at contact points. Do not mix dissimilar metals in the fastener assembly when used in saltwater or high-humidity environments. Follow applicable marine or structural codes for load-bearing fastener installations.
