Description

Key features

Premium Property Class 12.9Quenched and tempered from alloy steel to deliver a nominal tensile strength of 1200 N/mm² and yield point of 1080 N/mm², preventing bolt elongation, bending, and shock fractures in rocky soil conditions.

Metric Fine Thread Pitch (M16 × 1.5)The fine 1.5 mm thread pitch provides superior resistance against vibrational loosening compared to standard coarse threads, allowing accurate preload retention and secure clamp force.

Precision 27 mm Unthreaded ShankThe unthreaded solid shoulder ensures the primary shear boundary between blade and flange rests on the solid steel shank, eliminating stress risers on the threads and protecting mounting holes from elongation.

Supplied Complete with NutIncludes a matched high-strength nut suited for the 12.9 stress rating, ensuring durable, play-free blade attachment (typically installed in pairs of 2 per tine).
