A U-bolt, shaped like the letter U and threaded at both ends, has conventionally served as support for pipework conveying fluids and gases. Historically, U-bolts were quantified using terminology specific to pipe work engineering. Engineers would specify a U-bolt size based on the pipe it supported; for instance, they might request a "40 Nominal Bore U-bolt," a term familiar solely to those in the pipe work field.

Interestingly, the "40 nominal bore" designation doesn't directly correspond to the U-bolt's physical size or dimensions. Instead, it refers to the inside diameter of the pipe being supported. Engineers use this measurement to assess a pipe's fluid or gas-carrying capacity during design.

However, since U-bolts are now utilized by a broader audience to secure various types of tubing or round bars, a more user-friendly measurement system becomes essential to accommodate this expanded usage.
