Professional Applications & Engineering Value

This M2 thin hex nut in 316 stainless steel is engineered to solve critical challenges in precision engineering. Its thin profile is essential for modern, miniaturized electronics, medical devices, and instrumentation where space is at a premium. The coarse metric thread (M2 x 0.4 mm) facilitates rapid assembly in automated production lines while resisting loosening under dynamic loads. Manufactured to DIN 439B and ISO 4035 specifications, it ensures perfect compatibility with corresponding metric bolts, eliminating fitment issues. The 316 stainless steel material offers exceptional resistance to pitting and corrosion from chlorides and acids, making it a reliable choice for demanding applications in chemical processing, marine hardware, and food-grade equipment, thereby reducing maintenance frequency and lifecycle costs.

Specification Summary & Compliance
