Screw stripping-off occurs when the tension generated during tightening exceeds the nut’s shear strength. When this happens, the screw may turn inside the hole, reducing the torque value. As a result, the joint loses strength, the assembly’s reliability is compromised, and costly, time‑consuming repairs may be required. Several factors can affect stripping torque values, including applied torque, thread engagement, hole diameter, and friction.

Our Engineering Service team specializes in diagnosing and solving stripping problems. Through comprehensive testing and analysis, we pinpoint the root causes and determine the optimal tightening strategy and screw design to best suit your application and assembly requirements.

At CELO, we offer a wide range of specialized screw threads designed to prevent stripping across plastics, metals, and thin sheet materials.
