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.

Loose u-bolts cause accidents.

Vibration fatigue can loosen u-bolts if not re-tightened after 300 km.

How U Bolts Sizes are Measured
