Industrial S-M4-1ZI Self-Clinching Nuts

The S-M4-1ZI Self-Clinching Nut from PEM (PennEngineering) provides a permanent, non‑rotating M4 threaded receptacle that is clinched directly into sheet metal. It is part of PEM’s metric family for nuts—Types S, SS, CLS, CLSS, and SP—designed to install flush with the workpiece and create a sturdy thread anchor in thin metal without protruding hardware. Like other PEM S/SS/SP self‑clinching nuts, the S-M4-1ZI is intended for permanent installation on aluminum, steel, or stainless‑steel sheets, delivering a durable, vibration‑resistant threaded hole that remains fixed under load. The M4 internal thread supports standard metric fasteners and enables reliable assembly of sheet‑metal components such as enclosures and panels where a recessed threaded hole is required. The S-M4-1ZI is the M4 size option in this family’s metric lineup, offering PEM’s proven clinching geometry and compatibility with common sheet‑metal fabrication practices.
