S-90370A216 M30 ISO 4035, DIN 439B Hex Nuts

Key Features & Benefits at a Glance

• Space-saving thin profile with 15mm height for applications with limited clearance while maintaining full thread engagement
• Precise Class 6H thread fit ensures reliable mating with bolts and prevents loosening under vibration or load
• Heavy-duty M30 coarse threading (3.5mm pitch) enables faster assembly and reduced cross-threading risk in industrial environments
• Full ISO 4035 and DIN 439B compliance guarantees interchangeability and consistent performance across global projects
• 46mm external hex drive provides superior wrenching surface for high-torque installation with standard tools
• RoHS 3 and REACH compliance eliminates hazardous substances for safe use in regulated industries worldwide
• Right-hand thread design offers familiar installation for maintenance crews, reducing assembly errors

Professional Applications & Engineering Value

This M30 thin hex nut solves critical space constraints in machinery assembly, structural steelwork, and heavy equipment manufacturing where standard nuts would protrude excessively. The metric coarse thread (3.5mm pitch) combined with Class 6H thread tolerance creates optimal clearance for rapid installation while maintaining vibration resistance in high-stress applications. Engineers specify this ISO 4035/DIN 439B compliant component for conveyor systems, industrial frames, and agricultural machinery where the thin profile (15mm height) enables flush mounting without compromising the 46mm wrenching surface needed for proper torque application. The external hex drive accommodates both manual and automated installation processes, making it ideal for production lines requiring consistent, reliable fastening.

Specification Summary & Compliance

Manufactured to ISO 4035 and DIN 439B standards with Class 6H thread fit tolerance ensuring precise engagement with mating components. The M30x3.5mm coarse thread follows metric threading conventions with right-hand direction. Dimensions include 46mm width across flats and 15mm height. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, verified against 223 SVHC substances as of January 2022.
