Re: [T3] Leaky oil cooler -- tin fastener tangent

<x-flowed>The Allen wrench is 4mm but, yes, the fastener diameter is 6mm.  I did 
the brand-new screws and they look good while new but after a couple 
removings they start looking bad.  I originally bought hex bolts (10mm 
wrench) but for my application I can get enough torque to keep 'em AND 
they fit cosmetically.  Personally, I haven't found it necessary to 
monster-torque the screws down nor the hex bolts so I really don't see 
the worry with using an Allen wrench.  And an Allen wrench gives me far 
more purchase and control than a frickin' screwdriver!  I really think 
the stock screws were (are) a poor fastener choice.  If the button heads 
don't work for me then it will be the hex bolts but never the screw ones 
again!
