Re: Head Bolt Size

Mike,
 
   What's interesting about all this is that the U20 Head Bolt uses a 10mm 
Allen on the opposite end. I don't know how many of these head bolts I've seen 
where someone, drawing the conclusion that both sides are SAE, used a 3/8 Allen 
and damaged the fastener during the torqueing process.
