Description

Key features

Maximum Property Class 12.9Quenched and tempered from high-performance alloy steel, delivering a nominal ultimate tensile strength of 1200 N/mm² and yield point of 1080 N/mm² to prevent bolt elongation, shear deformation, and brittle fractures during rocky soil impact.

Metric Fine Thread Pitch (M14 × 1.5)The fine 1.5 mm pitch provides superior self-locking resistance against rotational vibrations compared to coarse threads, ensuring consistent preload retention and clamping force.

Precision 17 mm Unthreaded ShoulderKeeps the critical shear boundary between the blade and mounting flange completely on the solid, unthreaded shank, eliminating notch stress concentrations on the thread and preventing mounting hole elongation.

Complete Kit with Matched High-Strength NutIncludes a dedicated structural nut suited for property class 12.9 torque specifications, optimized for standard dual-bolt tine installations (typically 2 sets per blade) with compact flange thickness.
