Somewhere I found a web site showing large bolts with nuts that had smaller bolts all around the nut to tighten against the plate, I thought I saw them used on a cone crusher. Does anyone have the link to the web site?

Thanks!

No website, but I've seen pictures of the same product used on boilers, electric utility size.

I wish I could draw what I am trying to explain. They were putting the cone back together and were tightening up the 2 inch ring bolts. they snugged them up and then took a 1/2 impact wrench and tighten the ring of bolts threaded into the nut it tightened it without using a 4 foot bar on a wrench.

We used similar fasteners for front strut mounting on 797s for certain customers. They were testing them on other locations on the trucks as well but I can't recall where exactly, I'm thinking steering ballstuds but its been a couple years since I've worked on one.
