U-BOLT (DIN3570)

U-BOLT (DIN3570)
U bolt
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. U-bolt would be described by the size of pipe it was supporting.
U-bolts are also used to hold ropes together.

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)
