S-97289A135 M33 DIN 439B; ISO 4035 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction
• Reduced weight and material usage without sacrificing strength due to the thin profile design
• Precise and secure fastening ensured by the fine 2mm pitch and Class 6H thread fit
• Guaranteed dimensional interchangeability and quality through compliance with DIN 439B and ISO 4035 standards
• Easy installation and removal with a standard 50mm external hex drive
• Enhanced durability and long service life in demanding industrial applications
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives

Professional Applications & Engineering Value

This M33 thin hex nut is engineered for applications where space and weight are at a premium, without compromising on performance. The 316 stainless steel material provides exceptional resistance to corrosion from chemicals, saltwater, and other aggressive agents, making it ideal for marine, chemical processing, and food industry equipment. Its fine 2mm pitch thread offers a higher number of threads per unit length compared to coarse threads, resulting in superior vibration resistance and a tighter seal, which is critical in machinery and structural assemblies subject to dynamic loads. The thin profile allows for use in confined spaces where a standard hex nut would not fit, solving common design challenges in compact engineering projects.
