61008354 Hexagon Nut – Precision Fastening for SANY Engine & Chassis Systems
The hexagon nut with OEM number 61008354 is a fundamental component in SANY’s fastener portfolio, used extensively in the assembly of oil‑gas separator groups, engine mounting brackets, chassis crossmembers, and suspension linkages. As part of the SANY Oil‑Gas Separator Group, this nut secures the bracket (61000122) and the oil‑gas separator (60038917) to the engine structure, working in conjunction with hexagon flange bolts (60326571 / 60326573) to create a rigid, vibration‑proof assembly. Without a properly torqued hexagon nut, the entire crankcase ventilation system would be subject to misalignment and premature failure.
Every genuine 61008354 nut is cold‑formed from medium carbon steel (SAE J429 Grade 5 or equivalent) and then heat‑treated to achieve a hardness of 25–34 HRC, with a minimum tensile strength of 1,040 MPa for property class 10. The thread profile conforms to ISO metric standards (coarse or fine pitch, depending on application) and is manufactured with precision rolling rather than cutting, which improves fatigue resistance by eliminating stress risers. The nut also features a consistent hexagon shape (across flats tolerance to ISO 4759‑1) that ensures proper engagement with standard wrenches and impact sockets.
Corrosion protection is provided by a zinc trivalent coating (yellow or clear) that delivers 480–720 hours of salt spray resistance, critical for equipment operating in road salt, humidity, or chemical environments. The coating also acts as a lubricant, reducing friction during assembly and ensuring consistent torque readings. When used with SANY‑specified bolts, the 61008354 nut contributes to a fastener system with controlled friction and reliable clamp load retention.
Grade 10 Strength
Property class 10 nut with proof stress of 830 MPa and tensile strength of 1,040 MPa.
Precision Threads
Rolled threads (ISO 68-1) reduce galling and improve fatigue life by 30% compared to cut threads.
Corrosion Protected
Zinc trivalent coating provides 480h salt spray resistance, with optional topcoat for 720h.
DIN 934 Compliant
Meets international hex nut standards (ISO 4032 / DIN 934) and SANY OEM specifications.

Why Genuine SANY 61008354 Hexagon Nut Is Superior to Aftermarket Fasteners
Aftermarket nuts are often manufactured from lower‑grade steel (Class 8 or unmarked) that may not meet the required proof stress, leading to thread stripping, cracking, or loss of clamp load under vibration. The genuine 61008354 nut is manufactured from certified material batches and is 100% hardness‑tested to confirm Class 10 properties. This ensures that when torqued to SANY specifications, the nut will not yield or loosen over time.
Another common failure of aftermarket nuts is poor thread quality – either undersized or with burrs that cause galling during assembly. Galling creates false torque readings, leading to under‑tightening or over‑tightening, both of which compromise joint integrity. The threads on 61008354 are rolled to precise tolerances (6H) and are 100% thread‑go gauge inspected to ensure smooth engagement with SANY bolts.
In critical applications like the oil‑gas separator bracket (61000122) or engine mounting points, a failed nut can cause the entire component to loosen, leading to misalignment, leaks, and potential secondary damage. Using the genuine 61008354 nut eliminates this risk, as SANY’s testing includes vibration endurance up to 2 million cycles at full clamp load. For fleet operators, standardizing on genuine nuts reduces warranty claims and unplanned downtime.

Installation & Torque Guidelines for Hexagon Nut 61008354
When installing the 61008354 hexagon nut, always use a matching SANY bolt of the same property class (e.g., 60326571 or 60326573). Clean the bolt threads and nut threads thoroughly to remove any dirt, oil, or corrosion inhibitor. Apply a thin layer of light oil only to the threads and the nut bearing face if specified by SANY’s maintenance manual – do not lubricate if torque values are given for dry assembly, as lubricating will reduce friction and cause over‑tightening.
Tighten the nut using a calibrated torque wrench. For M8 hexagon nuts (typical size in oil‑gas separator groups), SANY specifies 20–25 Nm. For M10 nuts, 35–40 Nm. For M12 nuts (used in engine brackets), 80–90 Nm. Always follow a star pattern when tightening multiple nuts on a single component. After reaching the target torque, perform a final pass to verify all nuts are properly tightened.
Do not reuse a nut that has been torqued to specification and then removed; the threads may have deformed, and the nut’s prevailing torque characteristics (if any) will be lost. For critical joints, consider using a torque‑angle method (e.g., 20 Nm + 90°) as specified by SANY. Always keep spare genuine 61008354 nuts in your parts inventory.
