Rusty nuts and bolts can be a significant obstacle in the maintenance or restoration of any device or object. However, there are ways to loosen and remove a rusted nut or bolt with some simple methods. Let’s look at a few solutions to fix this!
Method 1 (Spray WD-40 on the rusted nuts and bolts)
Spray WD-40 around the rusty nuts and bolts. Wait at least ten minutes for the oil to soak in.
Stick the wrench in the hollow tube, and put the head of the wrench around the rusty nuts and bolts, giving you a longer wrench through which more pressure can be applied to the bolt.
If the box end wrench does not work because the head of the nail is damaged, replace the wrench in the hollow tube with a vice grip and try to loosen the bolt.
Method 2 (Use WD-40 and a hammer on rusted nuts and bolts)
Take a metal brush/normal brush and remove as much rust as you can manage.
Use a thread, wrap it around the bolt and spray some WD-40 until they’re completely saturated. Wait 30 minutes.
Strike the rusty with a hammer to try and unscrew the bolt.
Use a wrench to try and unscrew the bolt.
Method 3 (Use only a propane torch on the rusted nuts and bolts)
Take a propane torch and heat the rusty nuts and bolts by keeping the flame an inch to an inch and a half away from the bolt head. Heat the bolt for 15 – 20 seconds, and then heat the nut in a similar way.
Alternate between the nut and bolt for about 2 minutes, then use your wrench to try and unscrew the bolt
The heat should remove the corrosion that is causing the nail to stick.
Note – Do not spray WD-40 when using a propane torch as it is flammable.
