Clevis with bolt
Clevis with bolt
(OP)
Is it wrong to specify a clevis with an A325 bolt rather than the pin that usually comes with it?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Clevis with bolt
If you use a standard shackle and its pin the liability is on the manufacturer as long as the shackle is loaded/used according to their instructions and the users are trained in safe lifting practices.
There are also different shackle pin types available such as screw type, bolt type and cotter pin retained.

A 3/4" bolt has a strength in double-shear of 21.2 kips. This small hole for a 3/4" bolt will also result in a much greater amount of steel at the pin-hole. I was hoping to get about 16 kips capacity out of the connection. The table doesn't make it appear that I could use a Number 3 Clevis for a 3/4" rod.

Bribyk - that's got to be a good answer for almost every post on this site. Well done!

I'm not razzin' you, enginerding. I just laid the basic facts out there because you didn't provide much info on the application.
RE: Clevis with bolt
Not really much judgement required if you do all the numbers.

I second dicksewerrat. Go with a #3 clevis - threading for 3/4" rod is not a problem. Only issue you may have is that our #3 forging comes out of the trim die with a hole for a 1" pin so a 3/4" bolt would not be appropriate. The other guys forge their clevises without a hole so your 3/4" bolt would be OK if you sourced from them.
The only issue I have with using a bolt in place of a pin is that I don't like threads in the shear plane and it's not like you can order bolts in any thread length increment that you desire.
