Extra High-Tensile Bolt with Nut M12x1.25 - Part Number: 18030-1245

The Bolt with Nut Fastening Set (part number 18030-1245, property class 12.9, metric fine pitch M12 × 1.25, total underhead length L = 45 mm, thread length G = 22 mm, unthreaded shoulder 23 mm) is an ultra-high tensile structural fastener assembly engineered for soil cultivation machinery. Designed to withstand severe shear loads, high tensile stresses, and persistent rotational vibrations across compact and medium rotary tillers, walk-behind cultivators, and light harrows.
Key Features & Benefits
  • Maximum Property Class 12.9: Quenched 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 (M12 × 1.25): The fine 1.25 mm pitch provides superior self-locking resistance against persistent working vibrations compared to coarse threads, ensuring consistent preload retention and clamping force.
  • Precision 23 mm Unthreaded Shoulder: Keeps the critical shear boundary between the blade and mounting flange completely on the solid unthreaded body, eliminating notch stress concentrations on the thread and preventing mounting hole elongation.
  • Complete Kit with Matched High-Strength Nut: Includes a dedicated structural nut suited for property class 12.9 torque specifications, ensuring durable and play-free clamping on flanges with Ø 12.5 – 13 mm holes.
