S-93031A213 M24 DIN 439B, ISO 4035 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure.
• Secure left-hand thread engagement prevents loosening in applications with counter-clockwise rotational forces.
• Space-saving thin profile allows for use in compact assemblies where standard hex nuts are too bulky.
• Precise Class 6H thread fit ensures reliable, vibration-resistant fastening and reduces the risk of cross-threading.
• Fine 2mm thread pitch provides enhanced adjustment control and superior clamping force distribution.
• Guaranteed dimensional accuracy through compliance with DIN 439B and ISO 4035 international standards.
• Environmental and safety compliance with RoHS 3 and REACH regulations for responsible industrial use.

Professional Applications & Engineering Value

This M24 thin hex nut is engineered for specialized industrial systems where reverse-thread mechanics are critical. The left-hand metric thread is essential for components rotating counter-clockwise, such as certain machinery shafts, mixer blades, and automotive systems, preventing unintended disassembly. Manufactured from 316 stainless steel, it delivers exceptional resistance to pitting and stress corrosion cracking in marine, chemical processing, and high-humidity environments. The thin profile (12mm height) and fine thread spacing provide a low-profile, high-strength solution for weight-sensitive or space-constrained assemblies, ensuring long-term reliability without compromising performance under dynamic loads.

Specification Summary & Compliance

This nut conforms to DIN 439B and ISO 4035 dimensional standards, with a Class 6H thread fit for precise metric threading. Key dimensions include a M24x2mm left-hand thread, 36mm width, and 12mm height. It is manufactured to meet industrial specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
