Broken Ball Head screw for rear light

[dave_b]

One of the ball head screws has snapped leaving most of the threaded part still screwed in.

Best way to get it out?

I have replacement ball head screws for when I do get the broken bit out.

Super glue on end of a new one, screw it in, wait a few secs then screw it out and hopefully the snapped bit will have bonded and come out with it?

Drill out and use a stud remover
Drill out and retap with a smaller screw, superglue and then unscrew?

Easy outs / screw extractors are risky - they often snap leaving an extra hard bit of metal in the bolt you are trying to remove!

Did it shear off in use or trying to remove it? Have you checked whether you can turn it?

If tight I’d centre punch it and drill it starting off small say 3mm and work up the sizes. If it is an M8 then 17/64 is the optimum size. Hopefully a bit of drill heat and the drill bit snagging will unscrew it.

Good luck

Try one of these with the drill in reverse, if its not too tight the bit should grab and pull it out.

That’s the one.

They are hard plastic.
Sheered off when removing the rear light.

Sheered off at the red line, leaving most of the screw shaft in place.

I’m thinking just drill it out with progressively wider drills

I reckon that would do it

@Loz .....your the man. using your skills what is the part number for the plastic insert that goes into the bodywork for the expanding doo daas that hold the bumper on?

I'd melt a groove in it with a soldering iron, then unscrew it with a flat head screwdriver.

Can’t do that, the snapped off bit is too far down into the fixing.

Could you heat the tip of a small screw driver and let it melt in a little then screw it out?

If its only plastic, it shouldn’t be much of a challenge!

Drill a hole, tap in a torx bit & unscrew.

This was my last drilling out job! Exhaust manifold bolts!
