Four elements uniquely define any Ubolt, they are:

  1. Material type (for example bright zinc-plated mild steel or galvanised)
  2. Thread dimensions (for standard 1/2 inch )
  3. Inside diameter (for example 50 mm - the distance between the legs)
  4. Inside height (for example 125 mm)

Mild steel stretches under load. It is essential you re-tighten u-bolts approx 200 km after installation.
