Odd bolt type

Hi guys,
Anyone recognise this try or of bolt/screw head?
The ‘key’ I have has broken, and I can’t source a replacement!
Cheers

It's a torx pin head also known as a six lobe star. Wrenches arn't cheap though.

I think it is a Key Rex Tam 6 lobe security screw. I am not sure if the bits come in the security bit sets you can buy for £7/8 here is a link to a USA manufacturing company you could enquire with if you get stuck https://www.brycefastener.com/tam-6lobe ... crews.html

Or is it a Torx Plus Security?
Shows the Torx Plus here.

Bits are available apparently.

If possible, and if the "security" aspect isn't needed, I'd change that screw for a stainless socket head cap screw "allen pin" or similar.

Hi All,
Thanks so much for commenting.
I’ve looked at torx bits, but the torx bits I find only have 6 sides, whereas these screws have 7!
I’ve tried replacing, but the bolts seem to be an odd size, between M7&M8!
I’m guessing these must be custom completely!!
