Key Features & Benefits at a Glance
- Corrosion-resistant performance with 18-8 stainless steel construction, ideal for humid or chemically exposed environments.
- Space-saving thin profile (2.2mm height) for applications with limited clearance without sacrificing strength.
- Reliable left-hand threading prevents loosening under counter-clockwise rotational forces in specialized machinery.
- Precise Class 6H thread fit ensures secure mating with male threads, reducing the risk of cross-threading and vibration-induced failure.
- DIN 439B compliance guarantees dimensional accuracy and interchangeability in metric assembly systems.
- Fine 0.5mm pitch delivers enhanced adjustment control and vibration resistance in precision equipment.
- Environmental regulation adherence with full RoHS 3 and REACH compliance for global supply chain integration.
Professional Applications & Engineering Value
This M4 thin hex nut with left-hand thread addresses critical needs in assemblies where standard right-hand threads would unscrew under specific rotational stresses. Machined from 18-8 stainless steel, it provides excellent corrosion resistance for outdoor, marine, or food processing equipment, reducing maintenance frequency. The DIN 439B thin profile (2.2mm height) is engineered for compact spaces in electronics, automotive, or aerospace sub-assemblies, while the fine 0.5mm pitch offers superior clamping force distribution. Its Class 6H thread fit ensures reliable engagement in high-vibration environments, making it a trusted component for safety-critical reverse threading applications.
Specification Summary & Compliance
This nut conforms to DIN 439B dimensional standards with a 7mm width and 2.2mm height. Thread specifications include M4 left-hand metric fine thread with a 0.5mm pitch and Class 6H thread fit tolerance. Manufacturing and material compliance meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial fastener applications.
