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…
Error-proofing the complete tightening process improves manufacturers’ quality control process by reducing the number of defective products pulled from the assembly line and hedging the risk of liability from product failures in the field. A screw rattling loose in the avionics of a high-performance jet or from an implanted medical device can cause significant liability…
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…
Specifying a fastening sequence is a good manufacturing procedure to implement for many assembly projects. It can be critical for key torque applications. The wrong sequence could cause manufacturing failures and add additional rework expenses. The sequence of tightening bolts or screws can have a major influence on the resulting preloads. A good tightening sequence ensures…
