60326574 Hexagon Flange Bolt – Reliable Fastening for SANY Heavy Machinery
The hexagon flange bolt with OEM number 60326574 is a direct replacement fastener for SANY heavy commercial vehicles. As documented in the SANY Cylinder Head Cover Group, this bolt is a critical component used in engine assemblies to secure the cylinder head cover with consistent clamping force[reference:0]. It is also found in engine bracket groups, where hexagon flange bolts provide reliable, long-lasting connections between the engine and chassis, enhancing overall operational safety[reference:1].
The integrated flange design of 60326574 distributes load over a larger surface area, reducing the risk of embedment and preload loss. Unlike standard hex bolts that require separate washers, this design simplifies assembly and eliminates potential loosening from washer failure. The bolt meets international flange bolt standards including DIN 6921 and ISO 4162, ensuring compatibility with original SANY specifications[reference:2][reference:3].
Every genuine 60326574 bolt undergoes rigorous quality control including hardness testing, dimensional inspection, and coating adhesion verification. This ensures that each bolt delivers consistent clamping force and fatigue resistance throughout its service life.
Grade 10.9 Strength
Minimum tensile strength of 1,040 MPa, yield strength of 940 MPa for extreme clamping loads.
Integrated Flange
Serrated flange eliminates need for washers, ensures even load distribution and vibration resistance.
Corrosion Protected
Zinc flake coating provides 480-720 hours salt spray resistance, Cr(VI)-free[reference:4].
DIN 6921 Compliant
Manufactured to international flange bolt standards, fully interchangeable with SANY OE specifications[reference:5].

Why the Genuine 60326574 Hexagon Flange Bolt Outperforms Standard Fasteners
Standard hex bolts without flanges require separate washers, adding two additional components per joint and increasing the risk of incorrect assembly (e.g., missing washers). The genuine 60326574 bolt integrates a serrated flange that locks into the mating surface, preventing rotation and loosening under high vibration. This is critical in applications such as front suspension assemblies, where the SANY system employs numerous high-strength fasteners including similar M18×90 Grade 10.9 bolts to ensure structural integrity under dynamic loading conditions[reference:15].
Aftermarket fasteners often use lower grade materials (8.8 or lower) and poor plating, leading to premature corrosion or thread stripping. The 60326574 bolt is manufactured to Grade 10.9 specifications, with a minimum tensile strength of 1,040 MPa. This provides a safety margin of over 30% compared to standard 8.8 bolts (which have only 800 MPa tensile strength)[reference:16].
The zinc flake coating on genuine 60326574 bolts provides proven corrosion resistance of 480 to 720 hours in neutral salt spray testing (ASTM B117 / DIN EN ISO 9227-NSS)[reference:17]. This is essential for vehicles exposed to road salt in winter or moisture in mining environments. Aftermarket alternatives may use basic zinc plating with less than 100 hours of corrosion protection.

Correct Installation of Hexagon Flange Bolt 60326574
Before installing the 60326574 bolt, ensure the mating surfaces are clean, dry, and free of oil, paint, or debris. The flange surface must contact the component directly without any washers. Apply no lubrication unless specified by SANY, as the serrated flange requires friction to lock effectively. For dry installation, tighten the bolt using a calibrated torque wrench following SANY specifications (for M18 flange bolts, typical torque is 280–330 Nm depending on thread pitch)[reference:21].
For critical assemblies such as engine brackets and cylinder head covers, always follow the SANY torque sequence (usually cross-tightening pattern) and tighten in at least two stages. After the first 50 operational hours, re‑torque the 60326574 bolt to verify clamp load integrity. Do not reuse the bolt if the flange serrations appear flattened or if the threads show signs of galling. Always replace with new genuine 60326574 bolts when performing major maintenance on suspension or engine components.
