this kind of a screw?

amandstu

I know the picture is poor but what I am showing is a normal (ie not Philips) shape at the head of the screw (where the screwdriver fits) except for the fact that the middle section of the channel is flush with the head.
So effectively there are 3 sections (across the diameter)
1: a line from the circumference of the head of the screw extending ,say, 2/3rds of the way to the centre
2: no channel at all
3: a second line (the mirror image of the 1st on the opposite side of the head)
As you look at it it looks like a line across the diamwter with a missing section in the middle.
Hopefully that just shows up in the picture!
Can I get a tool to undo these screws-or are they designed to be tamper proof?

M cebee

could you take another picture:)

i think i know the screw
you can prob get a bit in those security bit sets at the diy shops

is it the spanner screw in the link

You could cut a section out of a screw driver to make it fit

If I'm stuck I use a needle nose pliers.

Thanks all
@M cebee
Here's a better pic (not so close )It is similar to the "spanner " shape in your link but the 2 "holes" are wider -more like lengths of channel (each about 1/3 in length of the diameter of the head)

@ted1 Yes I thought of that.

@BassboxxxIt is too small though for the needle nose pliers I have.

If you have two small flat head screw drivers try stick one in each hole and turn the screw should work

You could always just cut a slot out o one of your flat head screw drivers to allow for the bit ib the middle.

I'm sure you could get a tip to fit but chances of you using it again would be slim.

Old flat head you don't care about and have at it with a hack saw and file.:D

LIDL or aldi often sell sets with bits that would def fit these screws keep an eye on them this week

amandstu

Maybe they don't .Aldi has a 53 piece set today but none of them was the right one.
Lidl had hardly anything.
What about other shops? Woodies?

There's one in this set if you can wait on delivery

That's just a tamper proof slot screw/bolt.

You can get little sets of bits in the likes of halfords, woodies, maplin.

But the easiest thing to do is get an old slot screw driver and cut a notch in it, with a hacksaw/file.
