Step by step information to help you loosen a rusty Nut or bolt.
- Heat the connection with a propane torch if you can do so without any risk of damage or fire. It helps draw penetrating oil into the threads.
- Apply a liberal amount of penetrating oil in and around the joint, then wait ... and wait ... and wait. It can take anywhere from 10 minutes to several hours to loosen the joint.
- Strike the head of the bolt or nut with a cold chisel to shock the connection.
- Apply an open-ended wrench or socket of the proper size, and rap its handle sharply with a rubber or wood mallet.
