S-90593A022 M45 DIN 934 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with Class 8 strength grade, ensuring reliable performance in high-stress industrial environments.
• Enhanced corrosion resistance from the black-oxide steel finish, prolonging service life in harsh or outdoor conditions.
• Secure and precise fit with Class 6H thread tolerance, reducing the risk of loosening under vibration and dynamic loads.
• Optimized for quick installation thanks to the coarse 4.5 mm pitch and standard external hex drive, saving assembly time and labor costs.
• Broad compatibility with DIN 934 standard, ensuring interchangeability and consistent quality in metric fastener systems.
• Heavy-duty dimensions (70 mm width, 36 mm height) provide substantial bearing surface for distributing high clamping forces evenly.
• Compliance with environmental regulations including REACH and RoHS 3, meeting stringent industry requirements for safe and sustainable use.

Professional Applications & Engineering Value

This M45 hex nut is engineered to address critical challenges in heavy machinery, structural steelwork, and industrial equipment assembly. The black-oxide steel construction offers superior protection against rust and wear, making it ideal for applications exposed to moisture, chemicals, or fluctuating temperatures. With its coarse thread design and Class 6H thread fit, it ensures rapid installation and maintains tightness even under intense vibration—common in construction, automotive, and mining sectors. The DIN 934 specification guarantees dimensional accuracy and reliability, while the external hex drive allows for high-torque tightening with standard tools, reducing assembly errors and downtime in professional settings.
