The Couplemateā¢ CM604 is a Spring U-bolt kit for 60mm round axles. Designed to safely secure leaf springs to the axle, Couplemateā¢ļø calls these the āheavy-dutyā kits becauseĀ they have thicker U-bolts and fish plates.Ā

- Thread Type:Ā M16x2
- Coating:Ā Electro-Plated

This kit is supplied with:
- 4 x U-Bolts
- 8 x Washers
- 8 x Nyloc nuts
- 2 x Fish Plates
- 2 x Axle Pads/Spacers
Installation (User Guide)
Couplemateā¢ļø 60mm Round U-Bolt Kits are easy for trailer spring maintenance.
- Place U-shaped curve over axle beam.
- Align the centre spring bolt and U-bolt legs with the fish plate holes.
- Secure fish plate to leaf spring through supplied washers and nylock nuts. Tighten nuts to 100Nm with a socket.
Important:Ā Check U-bolts and re-tighten nuts after the first trip and every 250 km thereafter.
Safety Precautions
Do not re-use nyloc nuts.Ā Nyloc nutsĀ are often less effective after the first use. This is because the nylon material (the key component of a nyloc nut) has already once conformed to the thread profile.Ā
Do not use a rattle gun to tighten.Ā Rattle guns often tighten u-bolts too fast, too tight, and uneven. This can cause nylon overheat and risks undue wear.Ā
Ensure the axle has welded axle pads. If not, use theĀ axle pads supplied with the spring U-bolt kit.

Are Heavy-Duty U-Bolts worth it?
Within the industry, Trailer U-Bolts lack a standardised testing procedure.
However, Couplemateā¢ Engineers have developed its own rigorous testing method. In this process, we subject u-bolts, nuts, and fish plates to a static load test until destruction occurs.
All of our 16mm Heavy Duty U-bolt Galvanised Kit undergo a 200-tonne test. During this testing, the u-bolts in the right-hand image ultimately broke at the 23t threshold.
The u-bolts in the right-hand image broke at 23t.
