I want to get two phillips head screws out from a suzuki  handlebar thottlle body but both heads are very poor and worn and the screwdriver wont get a purchase, any ideas ?

Evening spooky, any chance of getting a junior hacksaw across them??.... or nowadays maybe a little Drexel disc, that way you can then use a standard slotted type screwdriver on them instead of a Phillips type. Used to do it a fair bit way back In the mists of time on the late 70's jap stuff when I were a lad😁 🔨🔨🔩
Best o luck...... cheers, Michael

As above, or first try an elastic band. Set it over the screw head, then the screwdriver might get a grip on it

Best way if you can is to cut a slot in it to use a flat blade screwdriver.

As an aside -  The screwheads used on most Jap bikes are not Phillips! They are actually JIS (Japanese Industrial Standard) which are almost but not quite the same as Phillips - thats why a Phillips driver often chew up the heads.  You can buy JIS screwdrivers but they are expensive.

No chance of a cut in the head as they are just about countersunk in the switch gear housing, after a bit of googling  and timbos  post i will try an elastic band , also found out about the JIS thing, somewhere i do have a genuine suzuki screwdriver, presumably that will fit  but it looks like they are  already a bit chewed... worst scenario is drilling them out i suppose,  thanks all..

elastic band worked  !!!!

I only discovered this a year or so ago after decades of struggling. I now have an excellent set of JIS drivers plus some hexagonal bits and chewed up screws are a thing of the past (unless someone's got to them before me of course).

I actually think the JIS drivers fit conventional Phillips better as well.

The one thing definitely NOT to use are pozidriv drivers in either Phillips or JIS screws as they have extra ridges that virtually guarantee they will cam out.

The rubber band tip sounds good.

Well as they say, everyday is a school day... never knew about the jiz.... oooo eerrr vicar, sorry I meant JIS screwdrivers. Honestly thought they were a standard Phillips head.

Nice one Spook! Never tried it myself, but glad to hear it worked

Plus one for yhe JIS screwdriver, bought a set of 3 for £27 and they stick like glue.

Phillips DESIGNED to cam out, so USA car assemblers couldn't overtighten them I believe.

At wirk, we recently had tiny Allen fasteners seized, and rounded them nicely with a worn Allen bit in an electric drill. Borrowed this off our handyman:

Hallelujiah, it worked like a charm. 5 out of 5 stuck fasteners released with ease!!! Very impressed, until I discovered £25 for 2 piece kit.

So, I bought a crappy copy for £3 in case it works <blushes>

So me and Rossco 500 decided it was about time we tidied up his well used Motolug  bike trailer. The fold out deck, which is hinged by two huge Allen bolts needed separated, so it can be shot blasted and repainted. I had tried everything to free these up, with no success, including hanging off a six foot bar, and taking it to a garage and letting them try with a big air impact gun.
But, yet again, the answer was HEAT! Yep, loads and loads of heat with my little MAPP gas torch, and eventually, swinging off a six foot bar paid off

Just spent an evening trying to remove a very rusty 6mm exhaust stud from project C90 - tricky as it could have easily snapped. Eventually got it out with lots of heat, WD40 and very gentle working with a set of mole grips.

But....oohhh the feeling of satisfaction eh Steve 👍👍
