• Global compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Broad compatibility with metric coarse threaded components, reducing inventory complexity

Professional Applications & Engineering Value

This M5 thumb nut delivers exceptional value in applications requiring frequent adjustments or tool-less maintenance. The zinc-plated iron material provides a cost-effective balance of strength and corrosion protection, ideal for electrical enclosures, machinery guards, and assembly jigs where exposure to moisture or handling is common. Its Class 6H thread fit and coarse thread spacing prevent cross-threading during manual installation, reducing assembly errors and rework time. The optimized 28.6 mm width offers superior ergonomics for operators wearing gloves, while the right-hand thread direction ensures intuitive tightening in standard industrial setups. Engineers specify this metric wing nut for prototyping, maintenance panels, and temporary fixtures where rapid disassembly is critical without compromising joint security.

Specification Summary & Compliance
