Torx
This pentalobular joint is commonly known as the registered name "Torx". Unfortunately data is not public so close assumptions are made here.
Shapes are defined with the following ratio's:
ra = 1 |
rb ≈ 0,72 ra |
rc ≈ 0,1 ra |
rd ≈ 0,175 ra |
The size table is close, but data differs slightly on the net. The table relates to designation and diameter where diameter = 2*ra.

Generic lobulars
With radii ra, rb, rc and number of lobes n given, rd is to be determined.
- Corner ae=pi/n radians or 180/n degrees, so for 6 lobes, ae is 30 degrees.
- Triangle:
- df=ra-rc
- dg+dh=rc+rd
- di=rb+rd
- cos(ae)=j
(omitting prefixes)
