Description

Key features

Maximum Property Class 12.9Forged from high-grade alloy steel and through-hardened to achieve a nominal tensile strength of 1200 N/mm² and yield point of 1080 N/mm², preventing bolt stretching, plastic deformation, or brittle fatigue under stone impact.

Metric Fine Thread Pitch (M16 × 1.5)The fine 1.5 mm pitch provides superior self-locking performance against persistent rotation vibration compared to standard coarse threads, ensuring consistent preload retention.

Precision 22 mm Unthreaded Solid ShankEnsures the shear boundary between the tine shank and rotor flange rests on the solid unthreaded body, preventing localized thread shearing and mounting hole elongation.

Supplied Complete with Matched NutPaired with an extra high-strength matching nut suited for 12.9 torque specifications, optimized for compact flange clamping setups.
