OK, what am I doing wrong here?
I am trying to bolt the center elevator bracket to the rear spar ( HS-411BPP / VA-146 to HS-609PP) using the specified bolts AN3-5A / AN960-10 washers / AN365-1032 nuts ). I am trying to torque them to 25 inch pounds using a brand new CDI 1501 MRMH torque wrench. I am holding the bolt head with a box end wrench and torquing the nut with the torque wrench.
Three of the bolts sheared off just as the wrench clicked. The one that remains is loose in the hole - it was torqued to the value but the bolt turns freely in the hole. I am pretty sure I used the correct bolts (I measured and looked it up). The bolts came out of bag 615 "Misc empennage hardware". The nuts had the plastic looking inserts inside. The bolts are gold/brass colored with "AFC" and "X" on the heads and fit in a 3/8" socket.
All three bolts sheared off with about two threads showing. I was not using much force.
Advice/Ideas???
Thanks in advance
