Stainless Steel U Bolt With Single Nuts – 316 is a U-shaped threaded fastener designed for securing, supporting, or clamping pipes, tubes, poles, brackets, and other round components. Manufactured from 316 stainless steel, it is suitable for marine hardware installations and other applications where equipment may be exposed to moisture, salt-laden air, or outdoor conditions. The rounded U-bolt profile fits around compatible components, while the threaded legs pass through a mounting plate, bracket, or prepared mounting holes.

Each U-bolt is supplied with one nut on each threaded leg and includes a flat mounting plate, as shown. Tightening the nuts draws the plate toward the curved section of the bolt, helping hold the positioned component securely against the mounting surface. This practical arrangement makes the product useful as a stainless steel U-bolt clamp for marine equipment, boat fittings, trailer components, pipe supports, rail assemblies, and general fabrication work. Correct sizing and installation are important because the required dimensions depend on the diameter of the item being clamped, mounting-hole spacing, material thickness, and available thread engagement.

Five variants are available to suit different installation requirements. Model S413S-80 has a diameter of 8 mm and a length of 80 mm. Model S413S-90 measures 10 mm × 90 mm, while model S413S-100 measures 10 mm × 100 mm. For applications requiring a longer U-bolt, model S413S-130 measures 10 mm × 130 mm. The largest listed option, model S413S-150, has a diameter of 12 mm and a length of 150 mm. These clearly identified product codes help buyers select and reorder the required variant.

The 316 stainless steel construction makes this marine U-bolt appropriate for installations where corrosion resistance is an important consideration. Grade 316 stainless steel is commonly selected for marine and outdoor hardware because it offers improved resistance in chloride-containing environments compared with many general-purpose stainless steel grades. However, stainless steel is not completely maintenance-free. Periodic inspection, freshwater rinsing, and cleaning may help reduce deposits and preserve the hardware’s condition, particularly around threads, nuts, plates, and contact points.

This product can be considered for boat maintenance, marine fabrication, trailer hardware, pipe mounting, pole fixing, and equipment-support projects. It may also be used as a heavy duty U bolt where its selected dimensions and the overall installation are suitable for the intended load. No working-load rating is provided, so buyers should not assume lifting or safety-critical capacity. For structural, lifting, overhead, or high-load installations, the required size, mounting arrangement, load rating, and compatibility should be confirmed by a qualified installer or engineer.
