Professional Applications & Engineering Value

This M4 thin hex nut addresses critical space constraints in electronic enclosures, precision instruments, and compact machinery where every millimeter counts. The metric coarse thread with 0.7 mm pitch delivers superior vibration resistance compared to fine threads, while the Class 6H thread fit maintains consistent clamping force without galling. Manufactured to ISO 4035 and DIN 439B standards, this external hex nut provides reliable performance in automated assembly environments. The thin profile hex nut design solves clearance issues in stacked components and confined spaces, making it ideal for PCB mounting, sensor brackets, and miniature mechanical systems requiring robust yet compact fastening solutions.

Specification Summary & Compliance

This metric thin hex nut features M4 size with 0.7 mm coarse pitch threading and Class 6H thread fit tolerance per ISO standards. Dimensions include 7 mm width across flats and 2.2 mm height. The product conforms to ISO 4035 and DIN 439B manufacturing specifications, ensuring dimensional precision and mechanical performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence for global industrial applications.
