M22‑1.50 DIN 439B Hex Jam Nut – Class 04, Extra Fine Thread, Plain Finish

The M22‑1.50 DIN 439B hex jam nut is a precision‑engineered, low‑profile locking nut designed for applications requiring extra fine thread engagement and minimal height. Manufactured to DIN 439B specifications and Class 04 strength, this jam nut delivers reliable locking performance when used against a standard hex nut or bearing surface. The extra fine 1.50 thread pitch improves torque control and resistance to loosening, making it ideal for automotive, industrial, and mechanical assemblies where vibration and space constraints are factors. Finished in plain (uncoated) steel for use in controlled or secondary‑locking environments.
