Bolt tightening
Bolt tightening
(OP)
I have a 1" dia bolt on which will act as a shaft or pin on which bearing will rest. Bearing will give only 4 kips of point load on 1" shaft. The shaft will be resting on two 3/16" thick plates. We will place nuts outside of plate to keep the shaft in place. AISC does provide pretension force in bolt if it is a slip critical or tension connection. But to me it is not. However I want to know Still how much nuts should be tightened. Thx a lot in advance.

Thx for ur time. There will be cables running on the bearings. As such there is no LATERAL FORCE. So bolt or shaft should stay and work even without nuts but we know in reality it doesnot happen.So I want to know that even though theoritically there is no lateral load, as per such and such spec we need to tighten the nut and bolt to such tension or torque.OR is there any spec stipulating minimum bolt torque for what so ever conn'n.

Double nutting with the second nut set to 1/4 past finger tight is an often used method.
RE: Bolt tightening
As you are talking about cables I would assume that the forces present will be extremely variable. If this is the case, and the connections is structurally important, you may wish to go for a more defined solution.
Split pins and 'castle' nuts are cheap and mostly fool proof.
Also look at locking compounds - These 'glue' the nuts into position. Try the Loctite web site under their industrial products page.
