160102120008A054 Double End Stud – Precision Threaded Fastener for Critical Engine Joints
The double end stud with OEM number 160102120008A054 is a high‑performance fastener used in SANY D09, D12, D13, WP12, and WP13 diesel engines for applications where a conventional bolt cannot be used due to access limitations or design requirements.
Typical applications include cylinder head clamping (in conjunction with nuts), exhaust manifold attachment, timing gear housing fastening, and water pump mounting.
This stud features threads on both ends – one end is typically a coarse thread for engagement into the engine block or cylinder head, while the other end is a fine or coarse thread to accept a hexagon nut.
The intermediate unthreaded section may be slightly reduced in diameter to provide flexibility and reduce stress concentration at the thread run‑out.
Genuine SANY double end studs are manufactured from heat‑treated alloy steel (SAE 4140 or equivalent) to property class 10.9 or Grade 8.8, depending on the application.
The minimum tensile strength is 1,040 MPa for class 10.9, with a yield strength of 940 MPa and a hardness range of 32–39 HRC.
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.
Each end of the stud features a chamfer or lead‑in to facilitate easy starting of nuts or threading into blind holes.
A zinc flake coating (Geomet 321 equivalent) provides 720 hours of salt spray resistance, preventing galvanic corrosion even in harsh mining and construction environments.
The coating is also Cr(VI)‑free, meeting modern environmental and safety standards for heavy‑duty equipment components.
Every genuine 160102120008A054 stud is 100% inspected for dimensional accuracy, thread quality, and surface hardness using automated optical and eddy‑current systems.
Using a sub‑standard aftermarket stud in critical engine joints can lead to thread stripping, clamp load loss, gasket blow‑out, and catastrophic engine failure.
Grade 10.9 Strength
Minimum tensile strength 1,040 MPa – 30% stronger than Grade 8.8 fasteners, ideal for high‑load engine joints.
Rolled Threads
Cold‑rolled threads on both ends increase fatigue life by 200% compared to cut threads, eliminating stress risers.
Corrosion Protected
Zinc flake coating (Geomet 321 equivalent) provides 720h salt spray resistance, Cr(VI)‑free.
Traceable Quality
100% dimensional and hardness inspection per batch, labeled with OEM 160102120008A054 and heat lot number.

Why Genuine SANY 160102120008A054 Double End Stud Is Superior to Aftermarket Studs
Aftermarket double end studs are often manufactured from lower‑quality carbon steel without proper heat treatment, resulting in lower strength (often Grade 8.8 or unmarked).
Using a sub‑standard stud in a cylinder head or exhaust manifold application can cause thread stripping, clamp load loss, and eventual gasket blow‑out.
The genuine 160102120008A054 stud is manufactured from premium chromium‑molybdenum alloy steel and heat‑treated to achieve consistent mechanical properties across every batch.
Aftermarket studs often have cut threads with sharp roots, which act as stress concentrators and reduce fatigue life, leading to premature thread fracture under cyclic loading.
Genuine SANY double end studs feature rolled threads on both ends, which work‑harden the thread root and eliminate stress risers, providing up to 200% longer fatigue life than cut‑thread studs.
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 stud breakage during removal.
The genuine 160102120008A054 stud is coated with zinc flake technology, providing 720 hours of salt spray resistance – ten times better than standard hardware.
For critical engine joints such as cylinder head clamping and exhaust manifold attachment, using the correct genuine double end stud is essential for engine reliability, safety, and long‑term performance.

Compatibility & Installation Guidelines
The 160102120008A054 double end stud is compatible with SANY D09, D12, D13, WP12G460E50, and WP13G500E30 diesel engines.
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: Cylinder head studs (for use with nuts), exhaust manifold studs, timing gear housing studs, and water pump mounting studs.
Before installation, clean the blind threaded holes thoroughly and ensure they are free of oil and debris. Use thread chasers to restore damaged threads if necessary.
Apply a thin layer of high‑temperature anti‑seize compound or light engine oil to the stud threads as specified by the SANY maintenance manual for the specific application.
Thread the stud into the blind hole by hand using two jam nuts locked together until the specified thread protrusion is achieved (typically 2–3 threads visible above the mating face).
Install the component over the stud, then fit the genuine SANY nut (matching thread and property class). Tighten the nut to the specified torque using a calibrated torque wrench.
Follow the prescribed torque sequence (e.g., star pattern for cylinder head nuts) and use torque‑angle method where specified.
Do not reuse double end studs that have been stretched or show thread damage. Always replace with new genuine SANY studs after removal, especially in cylinder head applications.
Never mix studs of different grades or manufacturers in the same assembly. Use only genuine 160102120008A054 studs with matching genuine SANY nuts for guaranteed performance.
Store studs in a dry environment and keep them in original packaging until use to preserve the corrosion protection coating.
