Difficult Screw

[chalkythebrave]

I'm trying to get into my dj turntables to replace a cable or two. On the base there are 15 or so screws which came undone fine, but one is causing me some problems. Here's a picture:

as you can see the screw head is getting mashed by the screwdriver. The screw is also embedded in a hole, so there's to be no hacksaw action to create a new head.

The screw isn't that important as there are many others doing a similar job, but i really need to get inside without damaging the chassis. Does anyone have any ideas to help? i've tried spraying some oil and leaving it for a while but that didn't work.

Thanks

As you say you can't use a hacksaw, and you probably can't drill it out either.... Then why not try and superglue the screwdriver point into the screw head,,, hold/leave it until it sets and see if it will turn,,,, push in and turn at the same time.....Just put a small spot onto the screwdriver point...... Clean any oil residue off the screwhead first...... Gotta be worth a try,,, and let us know if it worked !!

Drill it out with small HSS drill. Might be able to break the head off to gain access to equipment.

try a different driver bit first assuming youve been using a pz2 try a ph2 pz1 or ph1 or even a flat bit somtimes workes 2mm smaller than the diagonal groove[small electrical screwdriver for example]

And here I thought you were talking about the wife!

I too usually find that a terminal driver works best for difficult screws in equipment such as this.

Beg borrow or steal a Dremel. Or similar machine.

With a metal cutting disc cut a slot and use a suitable sized flat blade driver to remove the screw or simply cut the head of the screw off.

He can't do that for the same reason he cannot use a hacksaw blade.

It's in a hole.

Oh yeah

Memo to self: Read posts more carefully from now on.

The circular blade might get in where a hack saw can't.

BTW, the picture just appears to be all black to me?

Looks like a ph1 or ph0 need the correct size to loosen.

Does anyone have any ideas to help?

Is the screw securing a plastic or metal cover? If it's plastic, get a piece of steel tube (car hydraulic brake pipe might suit or, drill into a piece of rod), which will just fit over the head of the screw. File some "teeth" onto one end and cut (trepann) a small section away. If the cover is metal, do the same but, drill into a piece of silver steel then cut the teeth and harden the filed end, ie, heat to red and quench. Take the cover away, remove the screw with a pair of grips and, when the cover is replaced, put a suitable washer under the head of a screw which will replace the mashed up one..

I saw a device in Focus today that fits in to a drill and grips any screw and unscrews it. It worked well on the video. Cost about £10.

A pair of mole grips or decent pliers may be able to shift it.

Looking at the picture now its clearer at home you might be able to use the above mentioned Dremel method.

Have you tried a terminal driver yet?

Yeah Matty, I think a Dremel or the likes with a cutting disk would be able to cut a slot easily.
