Introduction: DIY Locknuts
Runner Up in the
Locknuts are great because they resist loosening from vibrations and torque. They offer an all in one solution to keeping bolts on tight (no lock washers, threadlocker solution). But what if you don't have any locknuts?
This Instructable will illustrate the steps to transforming any nut into a locknut. It is simple, easy and might save you a trip to the hardware store when you are in the middle of a project.
Step 1: Materials
You will need these materials:
- nut(s) that you want to make into locknuts
- glue- I have tested CA glue and rubber cement with success
- toothpick or cotton swab
Step 2: Apply Glue to Threads
Start by cleaning off the threads on the nuts to make a quality bonding surface for the glue. Use a toothpick or cotton swab to apply a dab of glue to the nut. The glue should be retained to one half of the nut- if you cover up all of the threads, it will be hard to start a bolt.
Depending on how much holding power you desire, you can either put a small drop on the threads, or cover an entire half of the nut. When you have finished applying the glue, set the nut on end and allow to dry per glue instructions.
Step 3: Use!
Once the glue has dried, try threading the nut onto a bolt. You should find that it is very hard to tighten- you will probably need a wrench. If you are still able to hand tighten the nut, add more glue and try again. Anything more than hand tight should be able to resist most vibrations and stray torque.
I noticed when I was experimenting with these homemade lock nuts that it is best if you do not mess with them more than necessary. The more you loosen/tighten the nut, the less locking power it will have. The glue will start to wear off after a couple of times threading.
