I have a 38T spline, it is "nearly" 20/40DP 45 inv serration to the SAE std, but if so it has been negatively corrected (I'm in the UK) by about .032" on dia.
Does anyone know if this could be to British Standard 3550? or maybe a 90 deg. straight sided serration.
What I really would like is the row of figures for BS3550 for 38T 20/40 45PA.
Thanks
