Hello Mike:
One important advice:
IF you already tightened this bolts too much (with the ft/lb -Inch/lb missunderstood)
PLEASE do not use those bolts... Destroy them to avoid future use!
Use new ones, they could already be seriously harmed by over tightened.. Even if you dont see any harm... They can probably fail without notice any time.
Hope this helps...
Saludos

Ref AC43.13-1B "Acceptable Methods, Techniques, and Practices AIRCRAFT INSPECTION, REPAIR & ALTERATIONS".,
PAGE 7-9
Table 7-1 "Recommended torque values (inch-pounds)"
FOR 5/16-24 BOLT
100-140 WITH TENSION TYPE NUTS
AND 60-80 WITH SHEAR TYPE NUTS.
Again, see that the values are in inch-pounds.

I am pretty sure if he did torque them to the Ft lb number instead of the in lb correct one he would have had to glue/weld/patch both halves back together to even try to retorque. <GG>
do not archive
