Andrew/Whittet-Higgins: One pitfall is not allowing the needed spacing in the assembly housing. If the components are not locked together properly, the machinery can fail prematurely. A second pitfall is assuming that a particular torque measurement for one component is correct for the entire assembly.Jim/Stafford: * Using a set-screw collar on a hardened shaft. The screw air does not "set," and holding power tools is greatly diminished.* Using a set-screw collar on thin-wall tubing, which can permanently distort bidy the tubing.* Specifying too thin a width on a clamp-type collar, leaving it too weak to resist distortion when the clamp-screw is tightened.* Specifying too thin a clamp-slot on threaded shaft collars where the collar must flex more in order to adequately clamp onto the threaded shaft.
