Description

Key features

Maximum Property Class 12.9Manufactured from quenched and tempered alloy steel, delivering a nominal tensile strength of 1200 N/mm² and yield strength of 1080 N/mm² to prevent bolt elongation, shear failure, and shock cracking.

Fine Metric Pitch (M16 × 1.5)The 1.5 mm fine pitch offers enhanced self-locking capabilities against persistent working vibration, allowing for more precise clamping preload control compared to standard coarse threads.

Dedicated Unthreaded ShoulderA precision unthreaded shank section (approx. 26 mm) provides a robust bearing surface inside the blade and rotor flange holes, preventing localized shear fatigue and hole elongation.

Supplied as a Complete SetMatched with a heavy-duty high-tensile nut designed to maintain clamping torque integrity under abrasive and rocky soil conditions.
