Description
Product Overview
The GBGS Double U Bolt Clamp is engineered for professionals and hobbyists who demand reliable, high‑strength fastening solutions for round tubing. Constructed from low carbon steel and finished with an electro‑galvanized coating, each clamp offers superior resistance to rust and corrosion, ensuring long‑term durability even in harsh environments. The clamps are sized to accommodate a 2‑inch (50 mm) outer diameter tube, featuring a 5‑1/2‑inch round bend that provides a secure, evenly distributed load across the pipe.
Each package contains two identical clamps, each with a thread diameter of 9.5 mm and a cutting diameter of 0.35 inches, allowing for easy installation with standard tools. The plate thickness of 3 mm adds rigidity, while the double‑U design creates a stable, self‑locking grip that minimizes slippage under vibration or dynamic loads. The product carries the part number G‑BG11‑T2‑F1 and meets a tensile strength of 300 MPa, making it suitable for demanding applications such as antenna mast mounting, automotive suspension components, and industrial piping systems.
With a weight of 2.42 pounds per pair, the clamps are lightweight enough for easy handling yet robust enough to support substantial loads. The design complies with metric measurement standards, ensuring compatibility with a wide range of international hardware and accessories. GBGS, a trusted manufacturer in the fastener industry, guarantees that each clamp undergoes rigorous quality control to meet exacting performance criteria.

Usage
These double‑U clamps excel in a variety of settings. In the telecommunications sector, they are frequently used to secure antenna cables and mast sections, providing a stable platform that can withstand wind and weather exposure. Automotive technicians rely on the clamps to attach brake lines, fuel hoses, and sensor brackets, benefiting from the strong grip and corrosion‑resistant finish that prolongs service life.
Plumbers and DIY enthusiasts find the clamps indispensable for joining PVC or metal pipes in residential and commercial projects. The 5‑1/2‑inch bend offers ample clearance for pipe insulation and allows for easy adjustment during installation. Because the clamps are pre‑drilled with a 0.35‑inch cutting diameter, users can quickly create the necessary holes using a standard drill, reducing assembly time and labor costs.
Beyond these core applications, the clamps are suitable for mounting lighting fixtures, securing garden trellises, and even creating custom rigs for hobbyist projects such as drone frames or model aircraft. Their versatility makes them a valuable addition to any toolbox, workshop, or inventory of industrial supplies.
