• Guaranteed dimensional accuracy and interchangeability through compliance with DIN 439B and ISO 4035 international standards.
• Reliable performance in standard industrial applications with a Class 04 strength grade, offering a robust and cost-effective steel construction.
• Precise and consistent thread fit with a Class 6H internal thread tolerance, ensuring smooth assembly and reducing the risk of cross-threading.
• Safe for use in regulated environments as it is fully compliant with RoHS 3 and REACH environmental directives.
• Easy installation and removal with a standard 30mm external hex drive, compatible with common wrenches for efficient maintenance.

Professional Applications & Engineering Value

This M20 thin hex nut is engineered from steel to address critical challenges in precision assemblies where space constraints and vibration are primary concerns. Its extra fine thread with a 1.5mm pitch provides a higher number of threads per unit length, significantly improving resistance to loosening under load and vibration compared to coarse threads. This makes it exceptionally valuable in industrial machinery, automotive subsystems, and precision equipment where metric fasteners with reliable, fine-adjustment capabilities are required. The thin profile allows for integration into compact designs without sacrificing the clamping force integrity, solving common issues of bulk and weight in advanced engineering applications. Manufactured to DIN 439B and ISO 4035, it ensures global compatibility and performance consistency.
