Mobile Bolt Extraction Service Near Me? The 230 Detailed Answer

In theory, metal screws – male-headed fasteners that fit into appropriate non-tapered nuts – can be removed and even reinstalled if necessary. Unfortunately, if overtightened or otherwise forced, screws can seize and break, making removal a challenge. Are you wondering how to remove a broken bolt before you continue with your home construction or patio building project? With the right equipment and technique, a broken bolt can be successfully pulled out so you can insert a new one.

STEP 1: Strike the center punch of your broken bolt.

Place the center punch as close to the center of the broken bolt as possible. Hit it directly with the hammer to create a starting point for drilling a pilot hole. A precise pilot hole is critical so you don’t damage the threads of the broken bolt when pulling it out. If the thread on the screw or screw hole is damaged, it may make it impossible to remove the screw. In addition, if the thread on the screw hole is damaged, you may not be able to use a new screw after the old one is pulled out.

STEP 2: Slowly use a left-handed drill to create a pilot hole.

Check the chart on your extraction kit to select the correct size left-handed drill (also known as the “reverse drill”) to drill a pilot hole in this broken bolt. Unlike traditional drill bits, which are considered right-handed and have clockwise threads, left-handed bits are designed with left-hand threads. This provides a better bite when using your drill bit in reverse to remove a fastener.

Pro Tip: If you’re buying a kit for the job, invest in quality; The last thing you need is a cheap set of teeth breaking during this process.

Set your drill in reverse and as slow as possible (ideally 20 rpm) and use the left-handed drill bit. The torque of reverse drilling (i.e. counter-clockwise) prevents you from further tightening the threads on the screw. Now place the drill over the center punch mark you made and, holding the drill, slowly drill a small pilot hole in the screw, about ¼ inch deep.

Hopefully, back-drilling your pilot hole will loosen the screw enough that you can use vise pliers to remove the screw. Remember, “right tight, left loose” – turn the screw to the left (counterclockwise) to remove. If the screw has not loosened at all, continue to step 3 to extract it.

STEP 3: Switch to an extraction bit.

For a stubbornly stuck bolt, you’ll need an extraction drill. Consult your extraction kit chart for the correct bit size for the screw size. The extraction drill is also a left-handed drill (but with a different purpose), so you’ll still use the reverse drill setting. Swap the first drill for the extraction drill in your drill, insert it into the pilot hole and gently tap your drill and the drill with a hammer.

STEP 4: Slowly drill backwards to remove a broken bolt.

Still use a very slow reverse drill setting, e.g. B. 20 RPM and start drilling into the pilot hole. Slow and gentle is key here: the drill bit is likely hardened steel, and if it breaks during this process, you’re in for an even more difficult extraction. The broken bolt should soon “grab” the extraction drill bit and start pulling out as you drill backwards. Continue slowly and steadily until the entire screw is fully extracted, ideally saving the threads so you can insert a new screw. phew!

STEP 5: Use a magnet to remove any metal filings left by the broken bolt.

Any metal shavings or shavings left in the threaded hole must be removed before installing a new screw. Place a strong magnet over the hole to attract the loose bits, or use compressed air to blow the threads clean. Do not skip this step or a new screw could seize or snap off.

The best practice you just learned should safely remove any broken bolt while also ensuring that you can reuse the hole to insert a new one later. If not, contact a local welding shop who should have the skills and tools to remove a broken bolt. And remember to insert all screws slowly and carefully in the future to avoid seizing and breaking off the upper part of the screw.

Broken bolts and hardware are the bane of a classic car enthusiast’s existence. It can ruin your day when they are bad. We’ve found that some methods of removing broken bolts are better than others. The process and time it takes to remove the old broken hardware depends on how delicate the area you are removing the broken screw from. Sometimes you can’t use heat because rubber, plastic, or paint surrounds the environment, or other your environment is a heavy cast of metal that you can harness with the power of fire and heat. Read below for our favorite tools for removing broken bolts and screws in metal.

Screw Extractor – The great thing about adversity is that it creates great inventions and solutions. Screw extractors just work; Drill a pilot hole or indentation in the hardware and push the extractors into the hole. This allows you to twist the extractor and the edges will dig into the pilot hole and twist the bolt out. This process works on most moderately tight screws and will get you out of a jam in most situations. Drill Bits – A good set of different sized drill bits will allow you to slowly drill out the center of a screw. This method is used when a screw extractor doesn’t work and you can’t use heat to loosen the broken screw. This process requires drilling out the bolt, starting in the center with a small 1/8″ drill bit, and working up the size until the circumference of the bolt is thin enough that you can knock it out with a chisel. This method requires care and patience as you can destroy the threads of the hole if you are not careful. This is one of the last lines of defense. Penetrating Oil – An oil is a tool? Yes! Use a good penetrating oil to penetrate the threads of the stuck bolt and help loosen the corrosion that usually causes the binding. Pro Tip – Heat the seized screw and the perimeter of the hole with a torch and apply penetrating oil to the area while it is still warm to allow the penetrating oil to penetrate the threads. Penetrating oil can work wonders but requires patience and you may have to let it sit on extremely stuck parts for hours or overnight. Screw Buster – This is a more modern tool than some of the others on the list, but works wonders. This tool requires the power of an air hammer or air chisel and the power of an impact wrench. When the air hammer vibrates the drill bit and hardware, you can also rotate the handle slowly to vibrate and loosen the hardware. This method works very well for delicate hardware like small screws. Pro Tip – Reduce the air pressure on your air hammer and allow the hardware to vibrate a bit before attempting to loosen it. Plasma Cutter – Is the broken bolt a hopeless case? Need to fix the threads? Sometimes when all hope is lost you may have to burn the broken bolt out of the hole. Use a plasma cutter and poke the screw out of the hole. This method is about the fastest, but also the most aggressive and should be used as a last resort. Pro tip: Use fresh consumables to try to reduce the size of the arc and the heated area.

Removing a screw or bolt can be annoying when the slots on the screw or the head of the bolt have been damaged by efforts to remove the fastener. This predicament can easily happen if the fastener is rusted or if you have used the wrong tool. A few slips of the screwdriver or wrench and the head of the screw or bolt can become so damaged or stripped that it’s almost impossible to get a good grip.

To your rescue comes this clever little accessory – the screw extractor. Screw extractors come in a variety of sizes for screws with diameters from 3/32″ to 1/2″ and larger. You can use them for all kinds of screws and bolts.

before you start

A screw extractor is a high-strength steel shank with a square head on one end and a reverse-tapered self-tapping screw thread on the other. The square head fits into a T-handle used to rotate the extractor. You can also grab and rotate the tool head with locking pliers.

The tapered threads are at the business end of the tool. These are designed to thread backwards (counter-clockwise) into the head of the screw or bolt after first drilling a pilot hole. The end is sharply tapered, allowing the extractor to penetrate deeper and tighter into the damaged bolt as the extractor is turned. Thus, as the extractor is turned counter-clockwise, it digs more and more into the damaged bolt as the damaged bolt retracts.

A T-handle is a useful accessory when using a screw extractor. Named for its shape, the handle fits over the end of an extractor. T-handles accommodate a variety of puller sizes, and many types also work with taps for threading holes. You can twist a screw extractor with locking pliers if you don’t have a T-handle.

Tip You must use the correct size extractor. Too big and not enough metal is left to properly hold the puller, damaging the threads holding the screw or bolt. Too small and the torque required for larger screws and bolts can cause the extractor to break. Use a chart to determine the correct size.

The bolt broke asymmetrically, leaving a protrusion in the center that reduced impact power. I followed the rest of the instructions and slowly extracted it with a drill.”
