Key Features & Benefits at a Glance
- Corrosion-resistant performance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
- Space-saving thin profile (1.8mm height) allows use in compact assemblies where standard nuts won't fit.
- Secure left-hand thread engagement prevents loosening in counter-rotating applications, enhancing operational safety.
- Precise Class 6H thread fit ensures consistent mating with bolts, reducing assembly errors and rework.
- DIN 439B compliance guarantees dimensional accuracy and interchangeability in metric systems.
- External hex drive design provides easy installation with common tools, speeding up maintenance.
- Environmental regulation compliance (RoHS 3 & REACH) meets global supply chain requirements without hazardous substances.
Professional Applications & Engineering Value
This M3 thin hex nut with left-hand threading addresses critical needs in machinery where reverse rotation occurs, such as mixer shafts, conveyor systems, and automotive components. The 0.5mm coarse pitch and Class 6H thread fit deliver reliable clamping force while resisting vibration-induced loosening. Crafted from 18-8 stainless steel, it offers excellent corrosion resistance in humid or chemical-exposed settings, reducing maintenance frequency. Its thin profile (1.8mm height) is engineered for space-constrained designs, enabling weight reduction without sacrificing strength. Complying with DIN 439B standards, it ensures seamless integration into metric-based industrial assemblies, from electronics enclosures to precision equipment.
Specification Summary & Compliance
This nut features M3 x 0.5mm left-hand metric coarse threads with Class 6H thread fit per ISO standards, ensuring tight tolerances for secure fastening. Dimensions align with DIN 439B for thin hex nuts (5.5mm width, 1.8mm height). It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming adherence to environmental and safety regulations for industrial use.
