Doesn't sound like much but multiplied by the number of those bolts in the assembly and the number of assemblies made in a given time period it adds up.

it's like the fasteners on my car hauler trailer - on first look they are an 8-point and i was trying to figure out wtf i would do about that, until i realised that a robertson would fit perfect - designed for quicker assembly.
porsche does seem a little screwy with their fasteners. how many different fasteners used to hold a transmission on? and if you try to get a clutch off, why the heck did they use allan head fasteners that strip out immediately when torque applied (note to bootleg - not sure what the torques are on those internal fasteners, but choose carefully if torques are large or there is any opportunity for them to seize in place - heat, differing metal types)?
