Its Grade 10.9 classification delivers exceptional tensile and yield strength, enabling it to withstand continuous stress, vibration, and heavy torque loads. The fine-thread M20 × 1.5 pitch ensures superior clamping force, preventing loosening under extreme operating conditions. With an extended length of 260 mm, this bolt is ideal for applications requiring maximum reach and deep penetration into mounting assemblies for secure fastening.
The hardened alloy-steel construction provides excellent resistance to deformation, fatigue, and corrosion, ensuring long-term durability even in harsh environments. Its precise machining guarantees consistent torque retention, improving reliability and mechanical stability across suspension, chassis, and engine mounting systems.
