M8‑1.25 Metric Hex Flange Top Locknut, Class 10, DIN 6927 / DIN EN 1664, Plain Finish

The M8‑1.25 metric hex flange top locknut is manufactured from high‑strength Class 10 steel for dependable locking in demanding, vibration‑prone applications. Produced to DIN 6927 / DIN EN 1664 standards, it features a prevailing‑torque top‑lock design that resists loosening without the use of nylon inserts. The integrated flange evenly distributes clamping force and eliminates the need for a washer, while the plain finish is ideal for dry, non‑corrosive automotive, industrial, and mechanical metric coarse‑thread assemblies.
