5/16 In. X 2-1/2 In. W X 5 In. L Coarse Zinc-Plated Stainless Steel U-Bolt

The National Hardware N222-471 U-Bolt is a precision-engineered stainless steel fastener built for both exterior and interior applications where corrosion resistance and holding power matter. This U-shaped bolt securely clamps pipe, conduit, and structural elements while resisting rust in harsh environments and outdoor installations where moisture and salt air accelerate deterioration.

Crafted from premium stainless steel and supplied with mounting strap already assembled, this U-bolt simplifies installation and delivers reliable, long-lasting performance. The non-magnetic composition makes it safe around sensitive electronic equipment and navigation systems, while the passivated surface creates an extra barrier against atmospheric and marine corrosion. Whether you're securing equipment, outdoor fixtures, or indoor piping, this fastener combines strength, corrosion resistance, and ease of use in one durable package.

Features and Benefits

• Stainless Steel Construction: Premium material resists rust and corrosion, maintaining a clean, bright finish even in challenging outdoor and coastal environments.
