Hello Experts,

Need some help over here. I am checking bolt strength of flange bolts. In between two flange there is another plate which is sandwiched, and 10 counter screw bolts are used to tighten them. Now during adding bolt it gives me only start edge and thread face to select. I have applied no penetration contact between 3 plates. so after my FEA run. it sems like sandwitched plate slips from its location as there is no bolt to connect it.

So please let me know how to add a bolt which goes through 3 plates.
