I checked all my tools and cant find it. Is this size available ? 

 

I need to remover a screw from a reel and T20 is too big and T15 is too small. I used all of my set (4!!) of different keys and none fit even Imperial as the reeel is US made.

 

Does anyone have an idea or link.

Picture?

T16?

There is no Torx socket size between 15 and 20 

there are Torx nuts but no sockets

 

Ok on my keyboard to give an idea

Maybe not torq but an other socket. I tried these too

You confused me by giving T sizes. It looks to be around 3mm or 4mm ordinary hexagon or Allen key socket.

 

But it may be an imperial size rather than metric. Are your keys metric?

You might need to find a set of imperial ones. Maybe 1/8" , 5/32", or even 3/16"

 

They sell them in HomePro.

 

EDIT. I see you already tried imperial.

Likely a 3.5 mm hex key socket given that it is between the two T sizes.

Allen key socket for sure.....

Given that the T sizes are measured point to point and Allen key wrenches are measured AF ( across flats ) I would wager it is a 3mm or 1/8” Allen wrench .

Forgot that.  Now all we need is an inside caliper ….

Or a 3.2 mm Allen. That is a rare beast.

You could say that I tried all those

So its between 3.3 and 3.8mm but not Torx.

 

So 9/64 (+/- 3.5mm) hex head or Allen key.

 

From what i could see of the tips, was the H3 too small and the 1/8 hex key , i assume on the cluster, also too small ?

So it’s not a Torx but a socket cap. There are quite a few non metric sizes and if you have a tight fastener the wrong size is quite capable of rounding the socket. I probably have the correct size as I have virtually every one of the smaller sizes, but, sorry, you need to be here ????

1/8 alen is too big

7/64 is too small

3mm

 

1/8 = 0.125

7/64 = 0.1094

3mm= 0.1181

 

Zeus is your friend 

 

Ill look if i have that i know i got one of those home pro metric ones too. Thanks all the help everyone.

At least there was a spot for a 3mm tip in the plastic case in the picture.
