How to put two nodes together

[Iceworld]

I have this case:
To simulate the screw in the junction of stud and track ,I want to get two nodes(stud mesh and track mesh) together,like a pin connection.I use CAE pick up the two nodes and tie together,but it didn't work.The track and stud will separate when put the load on it.and I also use *Equation in .inp,still didn't work either.

I have check the node coordinate,they are not exactly the same,like one is 0.,1.1985625E+03,15.875 the other node: -997.E-06,1.198562499E+03,15.875.
Is that the problem?
Is there other command that I can use in this case.Could anyone give me some suggestion

Thanks.

The *Tie may work if you spec a distance

Hi Portliner,
Thank you for your reply.
I remeshed,made that two nodes coincide and used *Equation,it finally worked.
