The values presented in these tables are representative and have been compiled for the user's benefit. Results can be influenced by any number of variables including: 1) excessive lubrication; 2) excessive design clamp load; 3) nicked or binding threads; 4) non-parallel mating surfaces; and 5) inadequate torque control, to name a few. Therefore; C-I, Inc. expressly disclaims liability of any kind associated with the approach of the data shown herein.
