61000211 Hexagon Flange Bolt – Precision Fastener for SANY Front End Accessory Drive
The hexagon flange bolt with OEM number 61000211 is a critical fastener used in the SANY Crank Shaft Pulley Group for D09, D12, D13, WP12, and WP13 diesel engines.
This bolt securely fastens the Torsional Vibration Damper (160102130004A102) and the Crankshaft Pulley (160102120008A063) to the front of the crankshaft, driving engine accessories such as the fan, alternator, water pump, and power steering pump.
The integrated flange eliminates the need for a separate washer, distributes clamp load evenly across the pulley surface, and prevents loosening under high vibration.
The SANY Crank Shaft Pulley Group serves as the essential interface between the crankshaft and the engine’s auxiliary drive systems, and the 61000211 bolts ensure the entire assembly remains perfectly aligned under extreme loads.
Each genuine fastener is manufactured from premium chromium‑molybdenum alloy steel (SAE 4140 or equivalent) and heat‑treated to property class 10.9 per ISO 898-1, delivering a minimum tensile strength of 1,040 MPa and yield strength of 940 MPa.
The threads are precision‑rolled rather than cut, which work‑hardens the material and eliminates stress risers at the thread roots, providing up to 200% longer fatigue life.
A zinc flake coating (Geomet 321 equivalent) provides 720 hours of salt spray resistance, preventing galvanic corrosion even in harsh mining and construction environments.
Every genuine 61000211 bolt is 100% inspected for dimensional accuracy, hardness, and surface finish using automated optical and eddy‑current systems.
A loose or incorrectly torqued bolt in this assembly can cause pulley wobble, belt misalignment, and severe vibration, leading to premature bearing failure in alternators, water pumps, and other engine accessories.
Grade 10.9 Strength
Minimum tensile strength 1,040 MPa – 30% stronger than Grade 8.8 bolts, ideal for high‑load pulley applications.
Integrated Flange
Flange design eliminates separate washers, distributes load evenly, and prevents loosening under vibration.
Corrosion Protected
Zinc flake coating provides 720h salt spray resistance, Cr(VI)-free, ensuring long‑term reliability in harsh environments.
Rolled Threads
Cold‑rolled thread roots increase fatigue life by 200% compared to cut threads, eliminating stress risers.

Why Genuine SANY 61000211 Hexagon Flange Bolt Is Superior to Aftermarket Fasteners
Aftermarket hexagon flange bolts are often manufactured from lower‑quality carbon steel without proper heat treatment, resulting in lower strength (often Grade 8.8 or unmarked).
Using a Grade 8.8 bolt in a pulley application designed for Grade 10.9 can cause thread stripping, clamp load loss, and eventual pulley loosening, leading to catastrophic accessory drive failure.
The genuine 61000211 bolt is manufactured from premium chromium‑molybdenum alloy steel and heat‑treated to achieve consistent mechanical properties across every batch.
Aftermarket bolts often have cut threads with sharp roots, which act as stress concentrators and reduce fatigue life, leading to premature bolt fracture under cyclic loading from belt tension and engine vibrations.
Genuine SANY bolts feature rolled threads that work‑harden the thread root and eliminate stress risers, providing up to 200% longer fatigue life than cut‑thread fasteners.
Poor corrosion protection is another common failure of aftermarket parts. Basic zinc plating rusts after 72 hours of salt exposure, leading to thread seizure and bolt breakage during removal.
The genuine 61000211 bolt is coated with zinc flake technology, providing 720 hours of salt spray resistance – ten times better than standard hardware.
For critical crankshaft front end accessory drive applications, using the correct genuine fastener is not optional – it is essential for engine reliability, safety, and long‑term performance.

It is used in Actlon 6×4/8×4 tippers, SY331, SY412, SY425 mining dump trucks, SYM3310 series, concrete mixer trucks, wheel loaders, motor graders, and STC truck cranes.
Application examples: Crankshaft pulley mounting, torsional vibration damper attachment, and general engine front end accessory drive fastening.
Before installation, clean the threaded holes in the crankshaft and ensure they are free of oil and debris. Lubricate threads with light engine oil.
Tighten using a calibrated torque wrench following the prescribed sequence and torque specification (e.g., 60 Nm ± 6 Nm for M10×1.5, 10.9 grade, dry assembly).
Do not reuse torque‑to‑yield bolts. Always replace with new genuine SANY fasteners after removal.
Never mix bolts of different grades or manufacturers in the same assembly. Use only genuine 61000211 fasteners for guaranteed performance.
Store bolts in a dry environment and keep them in original packaging until use to preserve the corrosion protection coating.
