Professional Applications & Engineering Value
Engineered for precision panel mounting in industrial equipment, these M4 press-fit nuts solve critical assembly challenges by eliminating secondary fastening operations. The 18-8 stainless steel material provides excellent corrosion resistance for demanding environments while the Class 4H thread fit maintains dimensional stability under vibration and load cycles. The press-fit round head design ensures flush mounting in electronic enclosures, control panels, and machinery frames where space constraints and reliability are paramount. With compatibility for 1.38mm minimum panel thickness and standardized 9.4mm drill preparation, these metric fasteners streamline production while delivering consistent thread engagement and long-term performance.
Specification Summary & Compliance
This metric press-fit nut features M4 x 0.7mm coarse threads with Class 4H thread fit per ISO standards, ensuring precise dimensional accuracy. The round head design measures 11.18mm OD with 3.31mm height for optimal installation profile. Manufactured to PEM® specification AC-M4-2 for 9.4mm drill preparation in panels from 1.38mm thickness. Fully compliant with RoHS 3 (2015/863/EU) environmental directives for global industrial applications.
