S-93737A119 M30 DIN 439B, ISO 4035 Hex Nuts

Key Features & Benefits at a Glance

• Enhanced corrosion resistance through zinc yellow-chromate plating, extending service life in harsh industrial environments
• Space-saving thin profile (15mm height) ideal for applications with limited clearance without compromising strength
• Precise Class 6H thread fit ensures smooth assembly and reliable vibration resistance in critical applications
• Fine 2mm thread pitch provides superior clamping force distribution and improved load-bearing capacity
• Class 04 strength rating delivers consistent performance under mechanical stress and repeated tightening
• Standard-compliant manufacturing (DIN 439B, ISO 4035) guarantees interchangeability and global project compatibility
• External hex drive design enables quick installation with common tools while preventing rounding during high-torque applications

Professional Applications & Engineering Value

This M30 thin hex nut addresses critical engineering challenges in machinery assembly, structural frameworks, and precision equipment where space constraints and corrosion resistance are paramount. The zinc yellow-chromate plated steel construction creates a sacrificial barrier against oxidation and chemical exposure, significantly reducing maintenance frequency in manufacturing plants, automotive systems, and outdoor installations. The fine metric thread with 2mm pitch enhances connection stability in high-vibration environments while the Class 6H thread fit maintains dimensional accuracy across production batches. Particularly valuable for retrofit projects and OEM applications requiring DIN 439B and ISO 4035 compliance, this fastener ensures seamless integration with existing metric threaded components while providing reliable long-term performance under dynamic loads.

Specification Summary & Compliance

Manufactured to Class 6H thread tolerance with precise M30x2mm fine thread spacing and right-hand orientation. Complies with DIN 439B and ISO 4035 dimensional standards for thin hex nuts. The zinc yellow-chromate plating meets RoHS and REACH environmental directives while providing corrosion protection. Class 04 strength classification ensures consistent mechanical properties across production lots. External hex drive configuration conforms to standard wrenching practices for secure installation.
