160102130003A052 Hexagon Flange Bolt – The Essential Fastener for SANY Oil Pan and Lubrication Systems
The hexagon flange bolt with OEM number 160102130003A052 is a critical component within the SANY Oil Pan Group, serving as a key structural fastener that secures the oil pan assembly and sealing system in D09, D12, D13, WP12, and WP13 diesel engines.
Within the SANY Oil Pan Group catalog, four units of 160102130003A052 are used per engine, complementing ten Bolt, Hexagon Flange, Large (61000135) fasteners to create a comprehensive oil pan retention system.
The bolt works in conjunction with several precision‑engineered components: the Oil Pan Sealing Gasket (160102130003A049) provides the primary oil‑tight seal, the Oil Pan Assembly (160102130004A016) serves as the engine’s oil reservoir, and the Retainer of Oil Pan (160102130003A050) and Oil Pan Support Block (160102130003A051) provide structural reinforcement.
The integrated serrated flange is one of this fastener’s most critical features. Instead of requiring a separate washer, the flange distributes the clamping load evenly across a wider surface area of the oil pan and its retainers, preventing localized deformation of the gasket and ensuring a leak‑proof seal.
The serrations on the underside of the flange act as a locking mechanism, biting into the mating surface to resist loosening caused by the intense vibrations inherent in heavy‑duty diesel engine operation.
Every genuine SANY 160102130003A052 bolt is manufactured from premium alloy steel and heat‑treated to achieve a minimum tensile strength of 1,040 MPa for 10.9 grade applications, delivering consistent mechanical properties across every production batch.
The threads are precision‑rolled rather than cut, a process that work‑hardens the material and eliminates microscopic stress risers at the thread roots. This provides up to 200% longer fatigue life compared to cut‑thread fasteners, a crucial advantage under cyclic engine loads.
A zinc flake coating (Geomet 321 or equivalent) provides 720 hours of salt spray resistance, preventing galvanic corrosion from road salt, moisture, and chemicals in mining and construction environments.
The SANY Oil Pan Group forms the foundation of the engine’s lubrication system. The oil pan serves as the engine’s oil reservoir, secured by the Oil Pan Sealing Gasket that prevents leaks. This assembly is reinforced with the Retainer, Oil Pan components that ensure proper alignment under operational stress.
The D12 engine produces a maximum torque of 2,150 Nm at 1,900–2,100 rpm, generating significant internal pressures and vibrations that demand the highest quality sealing components. The 160102130003A052 bolt is engineered to withstand these loads without loosening or fatigue cracking.
Every genuine 160102130003A052 bolt is 100% inspected for dimensional accuracy, thread quality, and surface hardness using automated optical and eddy‑current systems, ensuring consistent quality across every batch.
Grade 10.9 Strength
Minimum tensile strength 1,040 MPa – 30% stronger than Grade 8.8 bolts, providing exceptional clamp load retention for oil pan sealing applications.
Integrated Serrated Flange
Flange design eliminates separate washers, distributes load evenly across the oil pan surface, and features serrations that lock into the mating surface to prevent loosening under vibration.
Corrosion Protected
Zinc flake coating provides 720h salt spray resistance, Cr(VI)-free, preventing rust and corrosion from road salt, moisture, and chemicals in mining environments.
Rolled Threads
Cold‑rolled thread roots increase fatigue life by 200% compared to cut threads, eliminating stress risers that can lead to bolt fracture under cyclic loading.

Why Genuine SANY 160102130003A052 Hexagon Flange Bolt Is Superior to Aftermarket Fasteners
Aftermarket hexagon bolts are often manufactured from lower‑quality carbon steel without proper heat treatment, resulting in lower strength (often Grade 8.8 or even unmarked).
Using a sub‑standard fastener in an oil pan sealing application can cause thread stripping, clamp load loss, and gradual loosening of the oil pan assembly under engine vibration, leading to oil leaks and potential engine damage.
The genuine 160102130003A052 bolt is manufactured from premium chromium‑molybdenum alloy steel and heat‑treated to achieve consistent mechanical properties across every batch, with certification traceable to the heat lot.
Aftermarket bolts often lack the integrated serrated flange or have poorly formed serrations that fail to lock into the mating surface, allowing the fastener to loosen over time under vibration.
Genuine SANY bolts feature a precision‑machined serrated flange that provides superior vibration resistance and eliminates the need for separate lock washers or thread‑locking compounds.
Another common issue with aftermarket parts is poor corrosion protection. Basic zinc plating rusts after 72 hours of salt exposure, leading to thread seizure and bolt breakage during removal, especially problematic when the oil pan needs to be removed for engine service.
The genuine 160102130003A052 bolt is coated with zinc flake technology, providing 720 hours of salt spray resistance – ten times better than standard hardware.
For critical oil pan sealing applications, using the correct genuine fastener is not optional – it is essential for engine reliability, safety, and long‑term performance.

Installation Guide for Hexagon Flange Bolt 160102130003A052
Bolt replacement should be performed by qualified technicians following the SANY engine service manual for the specific engine platform.
Before installation, drain the engine oil completely and ensure the engine is cool. Remove the oil pan assembly to access the bolt locations.
Remove the old bolts and inspect the threaded holes in the engine block for damage, debris, or cross‑threading. Clean the threads thoroughly using a thread chaser if necessary.
Inspect the oil pan flange and retainer components for flatness. Warpage exceeding 0.2 mm requires replacement of the affected components to ensure proper sealing.
Clean the oil pan sealing surfaces on the engine block and the oil pan flange thoroughly, removing all old gasket material, sealant residue, and debris.
Position the new Oil Pan Sealing Gasket (160102130003A049) onto the oil pan flange or engine block as specified by the service manual.
Apply a thin bead of silicone sealant at the four corners where the oil pan gasket intersects the crankshaft rear main seal housing and the timing cover, as per SANY specifications.
Position the oil pan assembly onto the block, ensuring the gasket remains properly seated. Install the four 160102130003A052 hexagon flange bolts through the retainer components into the threaded holes.
Tighten the bolts in a star pattern following the prescribed torque sequence. Refer to SANY engine service manual for exact specifications (typically 20–25 Nm for M8 bolts, 10.9 grade, lubricated).
After tightening all bolts, perform a second pass to verify that all bolts are at the specified torque value, as the gasket may compress slightly after initial tightening.
Allow the silicone sealant to cure for the time specified in the service manual (typically 30–60 minutes) before refilling the engine with oil.
Refill the engine with the specified SANY engine oil grade and quantity, then start the engine and inspect for any oil leaks around the oil pan seal.
After the first engine run cycle (50 operating hours), re‑torque the oil pan bolts to ensure proper gasket compression and clamp load retention.
Never reuse old bolts after removal – the threads may have stretched, and the serrated flange may have lost its locking capability. Always replace with new genuine SANY fasteners.
Always replace the oil pan sealing gasket whenever the oil pan is removed. Never reuse a compressed gasket.
Use only genuine SANY components to guarantee correct fit, reliable sealing, and long‑term engine protection.
