The 160102130003A005 Hexagon Flange Bolt is a critical fastening component within the SANY Engine Block Group. It is used alongside other precision components such as Pressure and Temperature Sensors, Washer Seal components, Cylinder Liner units, O‑ring seals, Assembled Sealing Washers, and dowel pins. Together, these form the foundational core of SANY’s heavy‑duty diesel engines.
The SANY D12 engine, jointly developed with DEUTZ, features a displacement of 12.12 liters and six cylinders. It delivers 360 kW (490 hp) at 1,900‑2,100 rpm, with a maximum torque of 2,150 Nm. This high‑output engine relies on precision fasteners like the 160102130003A005 to maintain clamping force on critical assemblies such as main bearing caps, cylinder head, and flywheel housing.
The D12 engine meets Euro VI emission regulations through its advanced 1,800 bar common‑rail injection system, which improves fuel atomization and efficiency. Its low idle speed of 525 rpm reduces component wear, extending service life. Fastener integrity is essential for maintaining precise component alignment under these demanding operating conditions.
The 160102130003A005 bolt is manufactured from high‑strength alloy steel with a tensile grade of 10.9 or 12.9. The flange head distributes clamping load over a larger area, eliminating the need for a separate washer. The integrated flange also increases resistance to self‑loosening under vibration, a key advantage in high‑vibration environments such as concrete pumps and rock crushers.
Surface treatment includes zinc flake coating (Dacromet or Geomet) or black oxide with anti‑corrosion oil. Zinc flake coating provides exceptional corrosion resistance, typically lasting 500 hours in salt spray tests without red rust. This protection is critical for bolts exposed to road salt, coolant spills, or humid environments. For high‑temperature applications such as exhaust manifold attachment, a high‑temperature black oxide finish is used.
Thread specifications are metric coarse thread (M10, M12, or M14 depending on location). The thread pitch is standard for the diameter, ensuring compatibility with SANY engine block threaded holes. Bolt length is precisely matched to assembly stack height, with thread engagement typically exceeding 1.5 times the bolt diameter for optimal load distribution.
The D12 engine’s common rail system, split‑type cylinder head, and patented TOP‑Down cooling system all contribute to reduced energy consumption and noise output. Each of these systems relies on correctly torqued fasteners to maintain internal pressure integrity. The 160102130003A005 is used in cylinder head tightening sequences, main bearing cap mounting, and flywheel housing attachment.
The D12 engine has been widely applied in SANY truck mixers, dump trucks, truck‑mounted pumps, as well as compact rollers, excavators, port machinery, and ultra‑high‑pressure pumps. Wherever these engines operate, the reliability of each bolted joint depends on using genuine SANY fasteners. Aftermarket bolts may have incorrect hardness, poor thread fit, or insufficient corrosion protection.
Torque control is critical for proper bolt performance. Recommended tightening torque for a typical M10 bolt of grade 10.9 is approximately 45‑50 N·m for lubricated threads and 55‑65 N·m for dry threads. Torque‑to‑yield bolts require a two‑stage torque plus an angle tightening step. These are single‑use items that must be replaced every time they are removed.
The integrated flange includes a serrated under‑head surface that bites into the mating component, providing additional locking capability. In high‑vibration environments such as concrete pumps or rock crushers, this locking feature is essential to maintain clamp load over extended periods. The flange also seals the bolt hole against ingress of water or dust.
Why the 160102130003A005 Hexagon Flange Bolt Ensures Reliable Engine Assembly
High‑Strength Grade
The 160102130003A005 is manufactured to property class 10.9 or 12.9, delivering tensile strength of 1000‑1200 MPa. This ensures sufficient clamping force for high‑load engine components such as main bearing caps and cylinder heads.
Corrosion‑Resistant Coating
The zinc‑flake coating provides over 500 hours of salt spray resistance, protecting the bolt from road salt, coolant spills, and humidity. This extends service life and prevents seizing in aluminium engine blocks.
Integrated Flange Locking
The serrated flange face bites into the mating surface, providing superior resistance to vibration loosening compared to conventional hex bolts with separate washers. This eliminates a potential failure point.
Genuine SANY Accuracy
The bolt is manufactured with exacting tolerances for thread pitch, head height, flange diameter, and overall length. Aftermarket bolts often have inconsistent dimensions, leading to cross‑threading or improper clamp load.
Fastener role in D12 engine assembly and reliability: The 160102130003A005 hexagon flange bolt is used in multiple critical locations within the SANY D12 engine. For cylinder head attachment, a set of 26 bolts are tightened in a specific sequence. The combined clamping force must contain peak cylinder pressures exceeding 180 bar. If any bolt loses preload, the head gasket can fail, causing coolant or combustion gas leakage. Main bearing cap bolts must maintain consistent clamping force on the crankshaft journals; an unevenly torqued bolt can distort the bearing bore, causing oil pressure loss and eventual bearing seizure.
Every component within the 160102130003A005 fastener set is manufactured using premium alloy steel that is heat‑treated to achieve required core hardness and case depth. The thread rolling process creates work‑hardened thread flanks that resist galling. The flange face is serrated to provide micro‑locking. The group undergoes rigorous sampling testing for tensile strength, hardness, and torque retention. Using genuine SANY fasteners eliminates the risk of embrittlement, thread stripping, or fatigue failure that plagues generic hardware.
Installation of the 160102130003A005 hexagon flange bolt requires careful attention to torque specifications and tightening sequences. Before installation, inspect the bolt for any damage to the threads, flange, or head. Clean the threaded hole thoroughly using a thread chaser or tap if necessary. Do not use compressed air to blow out debris, as particles can lodge under the flange and create a false torque reading.
Apply SANY‑approved thread lubricant or locking compound as specified. Some applications call for engine oil on the threads to achieve the desired friction coefficient; others require dry assembly. Never use grease or anti‑seize unless permitted by the manual, as these can increase bolt tension at the same torque, potentially exceeding the elastic limit.
When tightening a set of bolts (e.g., cylinder head bolts), follow the prescribed sequence printed in the SANY service manual. The sequence begins in the centre and spirals outward. Tighten in three stages: first to low torque (20‑30% of final), then to intermediate torque (60‑70% of final), and finally to full torque. For torque‑to‑yield bolts, the final stage is an angle‑torque (e.g., 90°) that permanently stretches the bolt.
After torquing, use a torque angle gauge or a protractor to verify the final angle if applicable. Marking each bolt with a paint line after final tightening provides a visual reference for future inspection. A common installation error is overtightening, which can stretch a flange bolt beyond yield point, leading to eventual fatigue fracture. Undertightening allows joint separation under load, causing leaks or component movement.
For SANY equipment operating in severe service conditions such as mining, high‑vibration concrete pumping, or long‑haul transport, re‑check bolt torque at major service intervals (every 2,000‑5,000 hours). If any bolt is found loose, retorque it to specification and inspect the mating surfaces for wear. Replacing the complete set of critical fasteners at major engine overhaul (10,000‑12,000 hours) is recommended.

Bolt failure symptoms and replacement criteria: Common signs of a failing or failed fastener include visible looseness, oil or coolant seepage around the joint (indicating loss of clamp load), audible rattling or knocking from the engine area, and cracked or deformed bolt heads. The 160102130003A005 should be replaced immediately if there is any thread damage, if the flange shows signs of cracking, if the bolt has been stretched beyond its elastic limit (necking of the shank), or if corrosion has significantly reduced the cross‑sectional area. Torque‑to‑yield bolts must be replaced every time they are removed.
For severe service conditions (mining, desert, high altitude), inspect critical engine fasteners at every 2,000‑hour service interval. When replacing a bolt, always use a genuine SANY fastener of the correct grade, length, and coating. Reusing old torque‑to‑yield bolts is a leading cause of head gasket failure and bearing cap loosening. After installing a new bolt, follow the SANY service manual for torque sequence and final angle. A torque wrench should be calibrated annually.
To verify authenticity, inspect the 160102130003A005 bolt head for the SANY logo, the property class marking (e.g., 10.9 or 12.9), and a batch traceability code. Genuine SANY bolts have a consistent head marking, uniform flange geometry, and a high‑quality surface finish. Aftermarket bolts often omit manufacturer logos, have poorly formed flanges, or use inferior coatings that flake off easily. Always source from authorised SANY parts distributors.
When ordering the Hexagon Flange Bolt, provide your engine serial number (ESN) and the specific application (e.g., cylinder head, main bearing cap, flywheel housing). The 160102130003A005 is a standard fastener for D12 and D09 engines fitted in most SANY heavy trucks, dumpers, mixers, and industrial machinery. Confirm length and grade with the parts catalog, as different engine variants may use bolts of varying dimensions.
