Did you know that an incorrect screw fastening sequence can provide unreliable results? The wrong sequence could cause manufacturing failures and add additional rework expenses. Joint relaxation occurs to some extent in all fastened joints and is a problem in joints where gaskets, or parts such as spring washers and plastics, are utilized. It can…
Safeguarding against sequence and tightening failures requires you to deploy tools equipped with error-proofing capabilities that track each screw the tools fasten. Eliminate product rework and warranties by adding another layer of error-proofing to the manufacturing line. Common Sequence & Tightening Failures Under-tightening: Loose fasteners cause slippage between parts, placing unwanted shear stress Gasket creep…
Many joints consist of more than one fastener and tightening together surfaces that are not completely flat can be a very challenging torque problem. The sequence of tightening fasteners can have a major influence on the resulting preload and clamping force, which is what holds two parts together. With such joints, consideration should be given…
