nightmare bolts

[ned]

Hi all, these bolts are on the door of my truck. Every one I've went at so far, sheared before the allen key could budge it. I dont know why they exist. i wish they didnt!

does anyone have a method for dealing with them please?

as an aside, id like to buy a propane torch of some description, but dont know anything about them. would love to hear some recommendations if anyone has any, plz.

regards,
ned .

That pillar looks pretty ripe - I suspect heat might be your only answer, using something with a fine nozzle.

If Lubro-teknik LT8 wont shift it nothing will short of burning the rust off.

50/50 diesel/petrol painted on and left to soak in (you might have to clean off the pain first!).
and/or heat - move the diesel/petrol mix out of the way first!

Rough but necessary. Access only from below.

I hate hexagon sockets that do not have CoppaSlip on the threads.

Heat and an impact driver may shock them loose instead of shearing

....and I wish Mrs Robo would let me work in the nice warm kitchen

Plus gas, then Heat then a air wrench/impact gun. Only way it's going to come out, heat the panel not the bolt.

bit of flat bar with a hole in it...good weld to the bolt head and use the bar as your lever /hammer on it , once cracked cut the bar off and use grips

get new bolts from the dealer

You can try the usual methods of shock/heat etc, but
ultimately the sure fire way is to drill the heads off, and grip the stub with some small stilsons, mostly they do just come loose and you can extract with fingers let alone stilsons, if not grind them flush and drill the shank out with a left handed drill bit and usually the vibration causes the shanks to unscrew at this point. If after all that, the shank doesnt unscrew, just retap and be done knowing nothing short of a small nuclear incident was going to move it without.

I just detest hex screws/bolts completely. It's as if the manufacturers generally go out of their way to use the crappiest, softest metal possible for those things. I bet most on here have ended up hammering a Torx bit in at some point in time to remove a hex bolt which has a rounded out recess.

Try and nip it tighter first then loosen...

I think the main issue here is that floor it looks far to slippy for a workshop how can you hold thing still?

 

[DrNik]

hit them with a hammer, the surface area of the head makes them near impossible to remove, bet the threaded part is easily unscrewed

Hex head bit, in the ratchet

 

[normspanners]

Drill the heads off weld a 10 mm nut on whats left and unscrew.

If you have oxy/acet use a number 3 welding nozzle and heat the bolt through the hex hole on the head until it goes cherry red. You will hear the corrosion crack as it gives up!

This is the same method I use to remove the same type of bolts from brake disks on bike wheels.
