Female Torx Bit Size

Hi Guys



Now the lighter nights have arrived I'm just getting around to changing the discs on my combo van.



Had a look tonight and it seems i need to buy a female Torx socket to get the Calliper bracket/holder off the hub. Can anyone advise what size i need to buy as i can never seem to find a correlation between physical size and the T numbers on Torx stuff.



As the rounded out Torx 30 screws in the disks popped out easily these according to the law of sod will probably be a right barstool.


TIA Tom

A general rule for Torx sizes (well the female headed type, anyway) is:-

Torx T size = Fastener thread Diameter * 5

example for an M5 bolt = M5*5 = T25 bit.

"Anthony Britt" gurgled happily, sounding much like they were saying:

But for a "female" torx - ie, the opposite to a normal torx - the size is prefixed E. So it'd be an E25.

Get a set 'on a rail' for your socket set. Halfords sell them.

Thats Good Plan C, its just I'll probably never use the other sizes or are they becoming more common?

Plan A - Find the size + Buy it Plan B - Borrow Plan C - Buy a set!

They're used on my 25 year old car as well as newer one.

The very next day you'll need another size.

You'll loose it and end up having to buy one to replace it.

Buying good tools is never money wasted.
