torx screwdrivers

Getting a security set like 95315 would be a generally worthwhile purchase for dismantling electrical items.

At a pinch, if the Torx screws are not too tight, you can get away with filing the tip of a cheap long flat-blade screwdriver, to fit *exactly* across two opposite star points. There used to be a range of Philips boom boxes that used Torx screws to secure the case halves together, and these were recessed so deeply into the case rear, that I never did find a Torx driver long enough to deal with them. So I 'modified' a standard long screwdriver in the way described, and have used it ever since - that's many years - for dealing with one of these, when they cross my bench for repair.

A lot of things use Torx screws which are not recessed - so the set will come in useful. I had the same problem when trying to open my pressure washer - which is held together with recessed T15 screws. I bought a long thin T15 screwdriver from Halfords to get round that one - you may have to buy the T20 equivalent.

Yes, that is what I was thinking about buying.

Thanks. At first, I thought this would suffer the same problem: not being deep enough to reach, but I see that this particular set is a long(er) reach set so it might be worthwhile. I notice it's £10 more than the stubby size set though ;(

PS I notice that some sets are marked as Torx and others as "star". I realise that Torx is a trade mark but is there any difference between a star T20 and a Torx?

if there is a branch nearby.

When I wanted to open a fan heater for cleaning using masking tape to hold the bit onto a piece of brass tubing worked. Making the end of the tube into a hex shape would be even better.
