Marine Fastener U Bolt Screw Nut Washer Plate Ship Boat Shipyard Pipe Support

A U-bolt is a bolt in the shape of the letter U with screw threads on both ends.

U-bolts have primarily been used to support pipework, pipes through which fluids and gasses pass.
As such, U-bolts were measured using pipe-work engineering speak. A U-bolt would be described by
the size of pipe it was supporting. U-bolts are also used to hold ropes together.

For example, a 40 Nominal Bore U-bolt would be asked for by pipe work engineers, and only they
would know what that meant. In reality, the 40 nominal bore part bears little resemblance to the size
and dimensions of the U-bolt.

The nominal bore of a pipe is actually a measurement of the inside diameter of the pipe. Engineers are
interested in this because they design a pipe by the amount of fluid / gas it can transport.

As U-bolts are now being used by a much wider audience to clamp any kind of tubing / round bar, then
a more convenient measurement system needs to be used.

Four Elements Uniquely Define Any U-bolt:

1. Material type (for example: bright zinc-plated mild steel)
2. Thread dimensions (for example: M12 * 50 mm)
3. Inside diameter (for example: 50 mm - the distance between the legs)
4. Inside height (for example: 120 mm)
