304/316 Stainless Steel U-Bolts

DISLAB Precision

DIN standard stainless steel U-bolts with nuts for pipe and tube fixing

Stainless steel U-bolts are widely used to secure pipes, tubes, conduits, round bars, and structural members to plates, brackets, beams, and support frames. Their U-shaped body and threaded legs provide a stable clamping force for construction, plumbing, marine, electrical, automotive, and industrial equipment applications.

DISLAB Precision supplies DIN standard U-bolts made from 304 and 316 stainless steel, including round bend U-bolts for pipe fixing and square U-bolts for square tubing or flat mounting surfaces. Common thread sizes include M8, M10, and M20, with pipe sizes from 1/4″ to 20″ and custom lengths available according to drawings, samples, or installation requirements.

These 304 and 316 stainless steel U-bolts are supplied with matching hex nuts, with optional backing plates, saddle plates, or clamp assemblies. They are designed for corrosion resistance, easy installation, and reliable long-term fastening in outdoor, coastal, wet, and industrial environments.

Main Product Advantages

📦 Bulk Order Case – 316 Stainless Steel U-Bolts for Coastal Installation

A New Zealand customer specializing in marine and electrical construction ordered 8,000 pieces of M10 316 stainless steel U-bolts with two hex nuts per leg. The project required corrosion resistance for a coastal environment and accurate dimensions for standard electrical conduit mounting.

We confirmed the material grade, pipe size, leg length, thread length, and packing method before production. Each batch was inspected for thread quality, surface finish, and dimensional accuracy, then packed in clearly labeled cartons for international shipment.

This project shows how DISLAB Precision supports both standard DIN U-bolts and custom stainless steel U-bolt assemblies for export buyers. Common sizes can be supplied quickly, while custom dimensions can be produced according to drawings or samples.
