Description

Key features

Maximum Strength Class 12.9Hot-forged and precision heat-treated from alloy steel, delivering an ultimate nominal tensile strength of 1200 N/mm² and yield point 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 resistance against vibration loosening compared to standard coarse threads, allowing accurate preload control and consistent clamping tension.

Partially Threaded 20 mm Solid ShoulderKeeps the critical shear boundary between the tool and mounting flange on the unthreaded solid shank, eliminating stress concentrations on the threads and preventing hole wear.

Superior Fatigue EnduranceBuilt to endure dynamic vibration, centrifugal rotation, and high bending moments encountered in rocky or heavy clay soils.
