S-90519A842 M24 ASTM A108, DIN 439B, ISO 4035 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with black-oxide steel construction, ideal for harsh industrial environments and extending service life.
• Secure, vibration-resistant assembly ensured by the Class 6H thread fit and extra fine 1.5 mm pitch for precise, tight fastening in critical applications.
• Space-saving design and reduced weight due to the thin hex nut profile (12 mm height), perfect for applications with limited clearance.
• Reliable left-hand thread operation for specialized machinery and safety-critical systems where reverse threading prevents accidental loosening.
• Guaranteed mechanical performance with a Class 04 strength rating, providing consistent durability under load.
• Global compliance and interchangeability by meeting ASTM A108, DIN 439B, and ISO 4035 standards for seamless integration into international projects.
• Environmentally responsible sourcing with full compliance to RoHS 3 and REACH regulations, ensuring safety and sustainability.

Professional Applications & Engineering Value

This M24 left hand thin hex nut is engineered from black-oxide steel to solve critical challenges in demanding sectors like heavy machinery, automotive, and precision equipment. Its extra fine thread pitch and Class 6H thread fit deliver superior clamping force and vibration resistance, preventing joint failure in high-stress environments. The thin profile minimizes weight and saves space without compromising the Class 04 strength, making it ideal for compact assemblies. The left-hand thread is crucial for applications where standard right-hand rotation could cause unintentional loosening, enhancing operational safety. Compliant with ASTM A108, DIN 439B, and ISO 4035, this nut ensures reliability and interchangeability across global engineering standards.
