This lubricates the hidden thread and allows for a cleaner exit of the bolt. Grab some penetrating oil and squirt it into the gap you have created between the bolt and the housing. Gradually increase the rotation with each turn until you see the bolt start to rise out of the housing. Grab a socket wrench and start twisting the bolt or nut backward and forward, trying to loosen it further each time.įeel for the bolt to offer some resistance, and initially, always move the same distance forward as backward, returning the bolt to its original position. This, like the impact method, is one of the easiest. You can then twist the bolt out of the housing. You want either the bolt to turn in the housing, causing the minimum of damage or the nut to split right off the bolt.Īlso, by using this method, you should be able to get enough grip on the bolt or nut to clamp on some locking jaw pliers. Then place a chisel in the groove and hit it with a hammer. What you do is cut two or three grooves with a hacksaw or rotary cutting tool into the head of the bolt. Relief cutting is the most failsafe way of removing either rusted bolts or nuts that are stuck fast.
