Torx screw star geometry
Torx screw star geometry
(OP)
I have been searching the internet for the geometry of a Torx screw. I need the exact shape of the hexagon shape. First of all I need the T30 shape. I found some links on this site, but they don't work anymore...

Can anyone help me on this one? Maybe someone has a dxf file?
Thanks!

There is an ISO standard (ISO 10664) for the hexalobular drive system:

B ≈ 0,72 A
re ≈ 0,1 A
ri ≈ 0,175 A
A = 5.6 mm and B = 4.05 mm for T30. You need to purchase ISO 10644 if you want tolerances, gage dimensions, etc.
