OEM Carbon Steel 4.8/8.8 Grade Zinc Plated Hot DIP Galvanized HDG U Bolt with Nut for Electric Power

A U-bolt is a bolt shaped like the letter U, featuring screw threads at both ends. Traditionally, these bolts were primarily employed to provide support for pipework, specifically for pipes facilitating the passage of fluids and gases. Engineers used to refer to U-bolts based on the size of the pipe they were supporting. For instance, they would request a "40 Nominal Bore U-bolt," a term unique to pipe work engineering and understood solely within that context.

Interestingly, the "40 nominal bore" designation doesn't correspond directly to the actual size or dimensions of the U-bolt itself. Instead, it relates to the inside diameter of the pipe being supported. Engineers use this measurement to gauge a pipe's capacity for transporting fluids or gases.

However, as U-bolts have found application in clamping various types of tubing and round bars across a broader spectrum of industries, a more convenient measurement system becomes necessary to cater to this wider audience.
