Special Features

  • Premium 304 Stainless Steel Construction : Crafted from high-grade 304 stainless steel, these square U bolts offer superior corrosion resistance for long-lasting performance. The M8 coarse threads ensure secure fastening, while the 100mm(3.94") length and 25mm(0.98") width fit DN40 pipes perfectly. Ideal for trailer U bolts, industrial applications, and marine environments.
  • Complete 4-Piece Hardware Kit : Each set includes 4 premium U-bolt assemblies: stainless steel square U bolts (1" wide), zinc-plated nuts, rust-proof washers, and reinforced steel frame plates. Pre-matched components save installation time - no need to source separate bolts, washers or U bolt clamps.
  • Versatile Multi-Industry Applications : Perfect for securing pipes, trailer axles, automotive leaf springs, and machinery. Works with backpack blower racks, brackets, and various mounting systems. Suitable for construction, agricultural, automotive repair, and industrial & scientific applications.
  • Engineered for Maximum Durability : Features square head bolts with precision bending for a sturdy U-shape that resists deformation. The M8 stainless washers distribute pressure evenly while the square U bolts 3-4 inch wide variants maintain grip under heavy loads and vibration.
  • Easy Installation Guidelines : Simple 3-step process: (1) Align U-bolt legs with mounting surface (2) Add washers and frame plate (3) Hand-tighten nuts using standard wrench. Pro tip: Apply lubricant to threads for smoother assembly. Avoid power tools to prevent damaging these square U bolts' threads.
