Extra High-Tensile Blade Bolt M16 - Part Number: 18030-1645

The Blade Bolt (part number 18030-1645, property class 12.9, metric thread M16, shank diameter Ø D = 16 mm, total underhead length L = 45 mm, threaded length G = 22 mm, unthreaded shoulder 23 mm) is an ultra-high tensile structural fastener designed for severe shear loads, high tensile force, and shock resistance. Engineered specifically for securing power harrow tines, rotary tiller blades (1 bolt per blade), and plowshares or cultivator points (2 bolts per share).
Key Features & Benefits
  • Maximum Strength Class 12.9: Quenched and tempered from premium alloy steel, delivering a nominal ultimate tensile strength of 1200 N/mm² and yield point of 1080 N/mm² to prevent bolt elongation, permanent bending, and brittle fracture under stony impact.
  • Precision 23 mm Unthreaded Shoulder (Ø 16 mm): Ensures the primary shear boundary between the tool body and holder flange rests completely on the solid unthreaded shank, eliminating notch stress concentrations on the thread and preventing mounting hole elongation.
  • Calibrated M16 Thread Section (G = 22 mm): The partial thread length provides solid thread engagement and stable clamp preload retention against continuous soil impact and rotor vibration.
  • Dual Application Versatility: Suitable for both single-bolt mounting systems (1 bolt per rotary tiller blade) and dual-bolt ground-engaging configurations (2 bolts per plowshare/point).

Typical Application Scopes
Machinery Category Fastening Purpose Fitment Notes
Power Harrows & Cultivators Securing tines, blades, and wear plates High bending strength and radial shear resistance
Plows & Subsoilers Fastening shares, points, and wings Standard dual-bolt setup (2 bolts per share)
Rotary Tillers Mounting blades to single-bolt rotor flanges Fits Ø 16.5 - 17 mm holes; clamp thickness up to 20 mm
Installation Technical Note: Being a property class 12.9 structural fastener, pair with matched class 12 high-strength nuts (or high-grade prevailing torque lock nuts) and torque with a calibrated wrench. Ensure the unthreaded shoulder bridges the entire shear interface between tool and holder, and check fastener tightness after the initial hour of field operation.
