Wait for a While: Wear your protective gloves and sit for at least 20 minutes so the oil can cut through rust and corrosion. Besides, it will offer the oil enough time so it can fully soak in and loosen the bolt. 
Use Wrench Extender: Now Place a wrench extender bar above the grip of a box-end wrench to lengthen the wrench, and gets more torque to loosen the bolt. Then around the head of the bolt put in the head of the box-end wrench. Using one hand, let’s hold the wrench towards the end of the bar. Use the pliers with the other hand to hold the nut where the bolt contains strongly in place.

If you have an assistant, let’s ask him to hold the plies as it will be easier. Draw roughly on the end of the wrench so you can unite the seized bolt.

Turn out the tool: Then turn the tool quietly so you don’t break the easy-out. You will have to continue the turning till the screw shaft is out. 
Examine the condition: If the screw shaft is being immovable and still don’t come out, and then remove the easy out.

How to Remove a Rusted Bolt with No Head (The Most Effective Way)

Bolts are the most common gears that we use often. Since these metals cause rust. So they can degrade over time. But having patience, examine the situation, and applying proper strategy can help remove the rusted bolt successfully. 

Check the bolt:

Firstly, check the broken screw or bolt. A loosen bolt is almost near the breaking point. 

Then check the bolt is rusted or it includes a locking compound. Some manufacturer made their bolt with thread locker that can be softened with heat.

Determine if the rusted bolt is worth saving or not. A rusted bolt with reduced tensile strength can offer the needed force. If so, it will be better to change the bolt. However usually you can save screws and bolts by using locking pliers on the J-nut. 

Remove the rust from the bolt:

If you find the bolt is still workable, then eliminate the rust from the bolt as much as you can. To make it easy and effective you can use a stiff wire brush. An air compressor can remove the rust very quickly.

Pick the proper Tool:

Choose the ideal tools. Open-ended wrenches will possibly improve the levels of a bolt. That’s why a box with six points will be ideal for a 12.4. On the other hand, the nuts may become smaller due to the corrosion, so using the next smaller size you will have a better fit. Besides you can use an abrasive wheel joint with a die grinder to cut the nuts off exhaust fasteners

Turn it in the right direction:

Confirm that you are moving the bolt in the correct way. Some mechanics still make it wrong since they have ample experience. Especially they confused when working on upside-down and reverse direction. 

While most of the threads are left-hand loosened, old 60s style lug nuts and some ring gear bolts had to turn backward. 

Liquid thread loosener:

You can apply a liquid thread loosener to unstick the rusted bolt. Among tons of brands, you can use penetrating oil to overcome the maximum rust bond effectively. Furthermore, you can mix 50% ATF and homebrew of 50% acetone but ensure that you are protected from the fumes they discharge.

Soaking the threads:

Now using penetrating oil soak the threads properly. Remember it is essential to repeat applications and probably steep it quickly. At the same time, patience is crucial as it will save your time that had to spend drilling. Even you don’t need a hammer drill.

Attaining batter leverage:

You will find greater leverage with a breaker bar. Carefully use your force so you can feel each turn. If the pressure unexpectedly turns smooth, it means either you are stripping off the threads or destroying the bolts. To reduce the sore knuckles put on protective gloves. 

Heat is effective:

If you find the nut attached to the bolts, then you will have to apply a better strategy. Carefully applying heat can break the rust bond successfully and melt the locking compound to free the bolt. Ensure that you have clean off all the penetrating oil and use the open flame.

Many modern vehicle manufacturers use plastic that can be met and cause a fire if you don’t pay attention. You can use a spotter to notice telltale signs of smoke rather than tinted safety glasses. Use fireproof welder’s blankets to protect the crucial part and prevent accidents from fire. Many experts use a little amount of oxyacetylene tip to observe tight areas’ heat.

Paraffin as a lubricant:

Many experts use this method when need to remove rusted pipe plugs from cast iron. Applying heat on the iron they let the metal melting a candle over the threads. At this time, paraffin covers the threads and performs as a lube. But it needs to ensure using proper size and snug-fitting socket.

Last Resort:

An electric impact gun is the last option since it destroys the bolt more often. Wear protective gloves, glasses and proper impact sockets are the essentials for larger nuts. If it is possible, use the impact gun on the wedged area and use a wrench to hold the bolts.
