These Self-crimping nuts from AMECA are made for providing high-load capacity screw assemblies for sheet metal parts thicker than 0.8 millimeters. These sheet metals from AMECA may be made from light alloys, non-ferrous materials, or steel materials. The self-crimping nuts must undergo tests with different sheet metal types to identify the ideal fitting pressure. Moreover, the dimensions and measurements of the rough hole as well as its resilience must be monitored for optimal anchoring.
