Any restrictions against applying the torque from the Head side of a bolt?
Any restrictions against applying the torque from the Head side of a bolt?
(OP)
Hi All,
I have a (non aerospace) installation where due to a lack of access I was considering using either a socket head bolt or 12 point head bolt and I would apply the torque from the head side while holding the nut fixed with a custom made tool. I think you would usually apply the torque from the nut side, is doing it this way a problem?
I am using 1/2 dia bolts, with enough torque to reach 75% yield strength of the bolt.
The advantage of using these bolts as opposed to a hex head bolt is that a smaller socket is required for the same diameter bolt.
Thanks
