65mm Round Heavy-Duty U-Bolt Kit – Medium & Heavy-Duty Trailers

The Couplemate™ CM605 is a Spring U-bolt kit for 65mm round axles. Designed to secure leaf springs to the axle safely, Couplemate™️ calls these the “heavy-duty” kits because they have thicker U-bolts and fish plates. 

Product Specifications

  • Internal U-Bolt Width: 65mm
  • Internal U-Bolt Leg Length: 200mm
  • Thread Type: M16x2
  • Coating: Electro-Plated

Couplemate™️ often supplies Heavy-Duty u-bolt kits with trailer axle rebuilds over 1600kg (and up to 4500kg ATM).

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

16mm Individual U-Bolts

Installation (User Guide)

Couplemate™️ 65mm 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: Check U-bolts and re-tighten nuts after the first trip and every 250 km thereafter.

Safety Precautions

Do not re-use nyloc nuts. Nyloc nuts 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. 

Do not use a rattle gun to tighten. Rattle guns often tighten u-bolts too fast, too tight, and uneven. This can cause nylon overheat and risks undue wear. 

Ensure the axle has welded axle pads. If not, use the axle pads supplied with the spring U-bolt kit.
