How do I measure my shackle bolt?
Measure from the tip of the thread to the underside of the hex head.
Worn 5/8-inch Hangers
Yes, there is a fix for this problem.
- Standard hangers use a 4.5-inch shackle bolt, measured from under the head to the thread's top.
- Cut the head off a centre hanger leaving 2 x halves left.
- Use a longer shackle bolt and bolt the two centre hanger halves over the existing hanger.
- Weld the two 1/2 inch plates over the old worn hangers.
- The problem is now fixed.

Non-greaseable bolts fit inside a self-lubricating nylon bush and do not need grease. If your springs have nylon bushes, it is not advisable to change your pin to greaseable.
The knurl under the head has a particular purpose. The knurl locks into the shackle plate to help prevent the bolt from spinning during spring compressions. Broken welds are a good sign the bolts need replacement.
The knurl is welded onto the shackle plate on standard tandem and outback trailer springs to stop the bolt from turning. With a rotating bolt in the shackle plate, wear significantly increases.
How to tighten suspension bolts.
- Tighten 16mm x 100mm greaseable bolt until home.
- Back off 1/4 turn.
- You need a small space between your shackle plates and spring; otherwise, you will develop an annoying squeak.
- This squeak is due to no tolerance between shackle plates and spring.
