4 Ways To Remove Stripped, Rounded, Or Stuck Bolts | GMBN Tech's Guide To Stubborn Bolt Removal

No matter how competent you are working on your bike, it can still be easy to slip with an Allen key and round out a bolt head. It’s particularly easy with things like lock-on grip bolts and 4mm stem bolts - usually as you might be nipping them up with a multi-tool, which can be harder to engage. In this video Doddy shows you a few ways you can easily remove the offending bolt.

If you’re using the sacrificial allen key trick, bond the long end of the key into the screw. Once it sets, turn the short end with a small-diameter pipe or by grabbing onto it with an adjustable spanner for leverage. Once the bolt comes off, saw off the bonded end and round its sharp corners with a file. One sacrificial key lets you remove quite a few bolts.

A blow lamp will unbond the allen key, then scrape off any residue with a stanley knife. Use time and time again.

I used this video to help my son with a screw holding his laptop SSD in place. Can always trust Doddy - best video on the topic on KZfaq. PS used all the techniques. For the third, only had superglue, which didn't work. Using the extractor kit drill bit in reverse was enough. I was patient power Doddy's advice, and once it's drilled far enough in, there was enough friction that the screw started turning. Voila.

I've used most of them over time (the joys of old bikes and Daihatsu cars). I also keep a tube of metal epoxy putty with me when I go anywhere on/in any vehicle. I've used it similar to how you used the epoxy resin on bolt heads, I've used it to patch cracked frames and rims on bikes, fix holes in oil sumps on engines, fix go-pro mounts etc etc. It's very very useful stuff. Oddly enough, nearly all the times I've used it, has been fixes for other people.

Ive been in and around mechanic and electrical for mist if ny life machine shops...ive used extractirs and such before drilled out...i just had an issue in my motorcycle..one allen screw was a bit tighter then the others and stripped it a bit. It being in an isolated position could not cut slits, wrench. Didnt want to have to drill and did not have a four square to pound in. The glove trick. Magnificent. Just the little extra bite it needed. In all honesty i thought to fill the gap but had figured steel wool paper. Was not sure. Worked like a charm. Thank u. Saved quite a bit of trouble great tip.

Some good ideas here. Regarding drilling and using stud extractors/ezy outs. If it fails extracting using the head of the bolt you can using a hard metal cutting drill just drill straight into the centre of the bolt further down than the head. For this you'll need to use ezy outs by hand. A power tool will most likely snap them.

I've worked with the rubber band method too, but I couldn't get enugh traction on the inside of the fitting, so I wrapped it arouond the bolt head and then I used a hack which I've got from a car mechanic: I took some pliers and grabbed the outside of the bolthead with the rubber in between and turned the bolt in- and out, just a little bit and a couple of times until it felt really loose and then I was able to get rid of it. I'd be interested what you think about this hack! Happy new year!

Method 1.5: VICE GRIPS. If there is enough of the bolt head exposed (so many are countersunk which makes this method redundant in that instance)... Clamp the vice grips onto the bolt head ensuring there is some room for counter clockwise rotation. Put an Allen key in the head with the arm diagonally opposite to the vice grips (so you can hold the pair like a T bar giving even more torque to the job. Vice grips / pliers are also a forgotten gem for removing rounded screws... the smaller the vice grips the better for more precise grip. And (bonus?) tip... Use penetrating oil on the bolts... and try doing them up a pinch, sometimes breaking the friction clockwise is enough to let the penetrating oil in, and the bolt comes out with the standard alen key, no other trick needed. Heat is also another way.. but can damage aluminium, seals, paint, fingers, reputation...

Cheers for this; this has given me enough inspiration for my stripped bolt even though they are on some fairing screws on my scooter!, I have tried this before sometimes with disc rotor bolts it just created a dip and were truly stuck in there. I do have a high powered drill and metal bits too. One idea was to fashion some kind of mini crow bar as mine are mushroom flat head and getting a purchase with a hammer 🔨 nail hoofed claw was not feasible, out of an old piece of sheet metal or tool and bending the end like a hook maybe cutting a slit with my junior hacksaw blade. Definitely using my new WD-40 before I do anything to 😊, also I hear heat using a heat hot air gun can help with seized bolts
