M20‑2.50 Metric Hex Flange Top Locknut, Class 10, DIN 6927 / DIN EN 1664, Zinc CR+3

The M20‑2.50 metric hex flange top locknut is manufactured from high‑strength Class 10 steel for reliable locking in demanding, high‑load applications. Designed to DIN 6927 / DIN EN 1664 standards, it features a prevailing‑torque top‑lock design that resists loosening under vibration without the use of nylon inserts. The integrated flange distributes load evenly and eliminates the need for a washer, while the zinc CR+3 finish provides corrosion resistance, making it ideal for automotive, industrial, and heavy‑equipment metric coarse‑thread assemblies.
