Dear Erdem! Thanks a lot for your comment which is very much appreciated. We strongly recommend applying the required tightening torque successively by 1/3- or 1/4-turn increments starting with a screw of the user’s choice and then continuing clockwise to the next one. If screws are fastened reciprocally, there is a considerable risk that the shrink disc’s rings will not be positioned exactly parallel to each other. As a result, screws may be overloaded, and transmission of the needed torque may not be achieved sufficiently during operation. If you have any further questions or require more information, please don’t hesitate to contact us directly or visit our website www.ringfeder.com. Thank you!
