- Optimized for coarse threading (0.45mm pitch) providing faster assembly and reduced cross-threading risk
Professional Applications & Engineering Value
These M2.5 thin hex nuts deliver critical engineering solutions where space constraints challenge conventional fasteners. The zinc-plated steel construction provides essential corrosion protection for electronics, automotive components, and machinery exposed to moderate environmental conditions. The Class 6H thread fit maintains precise tolerances that prevent loosening under vibration, while the coarse thread pitch accelerates assembly in high-volume production environments. Manufactured to DIN 439B and ISO 4035 specifications, these metric fasteners ensure compatibility with global equipment standards, making them ideal for OEM manufacturing, maintenance kits, and precision instrument assembly where reliability and dimensional accuracy are paramount.
Specification Summary & Compliance
This thin hex nut features M2.5 x 0.45mm coarse right-hand metric threading with Class 6H thread fit tolerance per ISO standards. The nut profile conforms to DIN 439B and ISO 4035 dimensional specifications with 5mm width across flats and 1.6mm height. Manufactured from zinc-plated steel with Class 04 mechanical properties, these fasteners are fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives, ensuring regulatory acceptance for international industrial applications.
