In most cases, you can remove a bolt past unscrewing the nut from the commodities with a wrench. If the bolt is rusted or otherwise stuck in identify, however, y'all'll need to discover some other way to remove the bolt. If the hexagonal surfaces of bolt and nut oasis't been stripped, try heating the bolt with a propane torch to loosen it. In some cases, truly stuck bolts cannot be removed and need to exist cut off instead. Buy all of the supplies y'all'll need at a large hardware store or a home-improvement shop.

ane
Spray penetrating oil under the bolt caput and around the nut. ^[i] Penetrating oils like WD-40 will seep below the head of the bolt and under the nut and help to lubricate the threading on the bolt. This will make the bolt easier to loosen and will be particularly useful if the bolt is rusted in place. Give the oil at least twenty minutes to soak in.^[ii]
- Buy a penetrating oil at whatsoever hardware store. You lot might be able to discover it at a large supermarket also.
2
Slip a hollow piece of metallic over the handle of a box-finish wrench. Use a slice of metal that's at to the lowest degree 2 feet (0.61 m) long. This will effectively lengthen your wrench past 2 anxiety (0.61 grand) and will give you more than torque when you try to remove the stuck bolt.^[3]
- Yous tin can observe hollow metallic confined at large hardware or home-comeback stores. Wait for a bar that has a hollow inner bore of at to the lowest degree ³⁄₄ in (nineteen mm).
- If you like, bring your box-end wrench with you to the hardware store to make sure its handle fits within of the metallic bar you choose.
- Be aware that using a hollow bar to increase the torque of your wrench may damage or snap the wrench.

Try to unscrew the stuck bolt with the extended wrench. Hook the end of your box-finish wrench effectually the head of the stuck bolt, and concord the wrench at the very end of the extender bar. With your other mitt, grip the nut with a large pair of pliers. Pull sharply on the cease of the wrench to try to loosen the stuck bolt. Ideally, the penetrating spray volition accept weakened the bolt's resistance and so that it loosens.^[4]
- If information technology's too bad-mannered to concord both the wrench and pliers at one time, ask a friend or family member to assistance you by holding the pliers.

Utilise a pair of vice-grip pliers if the bolt or nut are stripped. If the sharp hexagonal sides of the stuck commodities have been stripped and rounded, a box-stop wrench will slip off when you try to loosen the bolt. Vice-grip pliers have teeth on the within of their rounded jaws and can be fastened tightly around the flat surfaces of a stripped commodities.^[5]
- Yous should be able to slip a hollow piece of metal over the end of vice-grip pliers only every bit you would over whatever other wrench.

i
Heat the commodities with a propane torch if information technology'due south still stuck. If the commodities doesn't budge when yous try loosening information technology with the extended wrench, it's time to try using heat to united nations-stick the commodities. Plow on a propane torch, and hold the flame most ¹⁄_two inch (xiii mm) away from the bolt. Keep the flame on the commodities for near fifteen seconds.^[6]
- The heat from the propane torch should crusade the bolt to expand.
2
Apply flame from the propane torch to the nut for 15 seconds. Once you've applied the flame to the bolt and it'due south begun to expand, switch and heat the nut for 15 seconds. Alternate between the nut and bolt for most two minutes total. The end of the bolt that you're not applying flame to will contract and the end that you lot're heating will expand. This will change the overall shape of the bolt.^[7]
- Ideally, the bolt's expansion and contraction will intermission whatever corrosion holds information technology in place.
three
Loosen the commodities with an extended wrench. Insert the end of your box-terminate wrench into a hollow metal bar. Hook the wrench onto the bolt and grasp the nut with a pair of large pliers. Concur the nut in position and pull on the end of the wrench. Give four-v sharp tugs and meet if the bolt moves.^[8]
- If the bolt yet doesn't loosen, oestrus it with the propane torch for another 10 minutes, or move on to another method.

one
Remove every bit much rust as possible with a wire brush. Accept a stiff-bristle wire brush and castor it aggressively confronting the rust crusted on the stuck bold (and corresponding nut). It's next to incommunicable to remove a bolt that's fully rusted in place, so scrub for iv-v minutes until you've scraped off virtually all of the rust.^[9]
- Large hardware stores may sell wire brushes specifically designed for stripping rust.
two
Saturate the threads with a rust-penetrating liquid thread loosener. Once virtually of rust has been stripped away, dunk both ends of the bolt with liquid thread loosener. Allow the liquid soak into the metal and work its way beneath the head of the bolt for about thirty minutes. Effective brands of rust-penetrating lubricants include Liquid Wrench, Pb Blaster, and Regal Imperial Maxfilm.^[ten]
- Exercise not use WD-twoscore for this. While it'south an effective lubricant, it's non constructive at penetrating through layers of rust.
3
Strike the head of the commodities 6-12 times with a hammer. One time the rust-penetrating thread loosener has loosened up the rusted commodities, hit information technology with a hammer to jar the commodities out of the position its stuck in. Blows from a hammer can also create micro-fractures throughout the commodities, making it easier to remove.^[xi]
- Vary the position of your hammer blows so they're not all in 1 place. Hit nigh all six sides of the stuck commodities at least one time.
4
Unscrew the rusted bolt with a long-handled socket wrench. The wrench'south long handle will requite you lot more than torque than a typical short-handled wrench. Hold on the very end of the wrench and pull by exerting constant, steady force per unit area.^[12] With enough forcefulness, the bolt should loosen and unscrew.
- If you're non sure of the size of the commodities, endeavour 3-4 different sizes of socket on the bolt until yous detect 1 that fits best.

Purchase a spiral extractor that matches the size of your bolt. ^[13] Find a correctly-sized spiral extractor that tin can remove your stuck bolt by measuring the bore of the threaded portion of the bolt. Accept this measurement to a hardware store and find a screw extractor that's about ¹⁄₇ inch (0.36 cm) narrower.
- If you lot accept the bolt measurement, the sales staff tin aid y'all find a correctly sized extractor.
2
Drill out the cadre of the stuck bolt with a spiral extractor. ^[fourteen]A spiral extractor is a long, thin piece of threaded metal that screws into an ordinary power drill. Set the point of the extractor into the heart of the bolt, and slowly clasp the ability drill's trigger. Drive the screw extractor down through the shaft of the bolt, and let it unscrew the bolt from within.^[15]
- Although this will destroy the commodities, information technology should make it much easier to remove.
iii
Remove the drilled bolt with a box wrench. If the spiral extractor doesn't remove the stuck bolt itself, pull the commodities out with a wrench. Set the end of a box wrench over the head of a drilled-out bolt and turn it counterclockwise to loosen the bolt.^[16]
- If the screw extractor shattered the commodities and pieces of the commodities are left inside the material that the bolt was screwed through, you may demand to requite the commodities head and nut a few blows with a hammer to remove them.
4
Cutting the spiral off with a reciprocating saw if nothing else works. If the screw extractor fails to pull out your screw—or if the screw is likewise rusted for the extractor to penetrate—your only other option is to cut the bolt off of whatever it's attached to. Insert a hacksaw bract into the reciprocating saw, and printing the blade confronting the shaft of the stuck bolt. Turn the saw on, and cut through the bolt and the shaft.^[17]
- Go along your fingers and hands clear of the blade when cutting through a stuck commodities.

A cold chisel is some other useful tool for knocking off the head of a stuck commodities.^[18]
A bolt is a thick piece of threaded cylindrical metal with a hexagonal caput on one end. A nut is a hollow hexagonal piece of metallic that screws onto the threads at the end of the commodities and tin exist tightened into identify. When the nut is tightened, it clamps firmly against whatever the bolt's metal rod passes through and holds it securely in place.
