S-93031A141 M22 DIN 439B, ISO 4035 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for chemical, marine, and outdoor applications.
• Secure left-hand thread locking prevents loosening in applications where standard right-hand rotation occurs, enhancing assembly safety.
• Space-saving thin profile (11mm height) allows for use in compact assemblies without compromising on strength or thread engagement.
• Precise Class 6H thread fit ensures smooth, reliable engagement with mating bolts, reducing the risk of cross-threading and assembly failures.
• Guaranteed dimensional accuracy and interchangeability through compliance with DIN 439B and ISO 4035 international standards.
• Fine thread pitch (1.5mm) provides a higher number of threads per mm for improved adjustment precision and vibration resistance.
• Environmental and regulatory compliance with RoHS 3 and REACH ensures safety in sensitive industries and promotes sustainable sourcing.

Professional Applications & Engineering Value

This M22 left-hand thread hex nut is engineered to solve critical challenges in industrial settings where reverse-motion or counter-rotational forces are present. Its 316 stainless steel material offers exceptional resistance to pitting and crevice corrosion, making it a reliable choice for chemical processing equipment, marine hardware, and food-grade machinery. The thin hex nut profile and fine metric thread (1.5mm pitch) enable precise tension control and secure fastening in confined spaces, reducing the need for frequent maintenance. By conforming to DIN 439B and ISO 4035 specifications, it ensures compatibility with global component inventories, streamlining procurement and assembly for MRO and OEM operations.
