Manufactured from high‑grade alloy steel and heat‑treated to property class 10.9, delivering outstanding tensile strength and resistance to shearing under heavy loads.
Threads are precision‑rolled after heat treatment, which work‑hardens the root radius and significantly improves fatigue resistance under cyclic loads.
Zinc plating with clear passivation provides excellent resistance to rust, even in humid or salt‑laden environments, ensuring long service life.
Every batch is sampled for hardness and proof load; each stud is visually inspected for thread defects, guaranteeing reliable performance.
This double‑end stud is used in the following SINOTRUK Howo assemblies and positions:
The WG9700220004 double‑end stud M10 is a critical fastener in many SINOTRUK Howo assemblies, providing a robust threaded connection where a nut is required on both ends. It is manufactured from high‑grade 40Cr alloy steel, which is first cold‑headed to shape, then heat‑treated to achieve a tensile strength of 1000 MPa (grade 10.9). The threads are rolled after heat treatment, which work‑hardens the root radius and dramatically improves fatigue life – essential for components subjected to constant vibration and thermal cycling.
In heavy‑duty applications, a simple bolt may not suffice when space is limited or when components need to be clamped from both sides. The WG9700220004 stud solves this by providing a permanent threaded post fixed into one component, allowing nuts to be torqued onto both ends. This design is commonly used for mounting transmission covers, intake manifolds, and exhaust systems where access for a wrench is limited on one side.
Installation of this stud requires care to avoid damaging the threads. Apply a thread‑locking compound (such as Loctite 243) to the end that will be permanently installed. Screw the stud into the tapped hole until it bottoms out or reaches the specified depth, using a double‑nut technique to grip the plain section. Allow the thread locker to cure, then assemble the components and torque the nuts to the specified value (typically 35‑40 Nm for M10 grade 10.9).
Quality control for the WG9700220004 includes 100% visual inspection of the threads for any defects such as nicks or incomplete rolling. Samples from each batch are subjected to hardness testing (32‑38 HRC) and proof load testing to verify compliance with ISO 898‑1. Dimensional checks are performed using thread gauges to ensure perfect fit with standard M10 nuts.
Environmental sustainability is integrated into production. The steel contains a high percentage of recycled content, and all manufacturing scrap is recycled. The zinc plating process is environmentally controlled with minimal waste. At the end of its long service life, the stud is fully recyclable as steel scrap.
For maintenance departments, the WG9700220004 stud is available individually or in multi‑packs. Each stud is packaged in a protective bag to prevent corrosion. Bulk orders are shipped in partitioned boxes with clear labeling. A certificate of conformance with batch test data is included with every shipment.
Field feedback from over 150 fleet workshops indicates that using genuine WG9700220004 studs eliminates fastener failures such as thread stripping or breakage, which are common with inferior aftermarket studs made from lower‑grade steel. Technicians report consistent torque readings and no galling during installation.
When ordering, always verify the required length and thread specification. The WG9700220004 is specifically designed for M10 x 1.5 applications with a total length of 55 mm. For other lengths, consult the SINOTRUK parts catalog. Technical support is available through your local dealer – no contact details are listed here, in line with our policy.
In summary, the WG9700220004 double‑end stud M10 is a small but essential fastener that ensures the integrity of critical connections in your SINOTRUK Howo vehicle. Its high‑strength material, precision‑rolled threads, and corrosion‑resistant finish make it the ideal choice for any heavy‑duty application.
During service, inspect the WG9700220004 stud for signs of rust, thread damage, or bending. Check that nuts can be run down freely by hand. Replace if any damage is found.
Apply a light coat of anti‑seize compound to the threads during assembly to prevent galling and ensure accurate torque readings.
Only the authentic WG9700220004 stud uses the exact steel grade and heat treatment specified by SINOTRUK. Imitations often use low‑carbon steel that can stretch or break under load, leading to catastrophic failure. The genuine stud is 100% hardness tested and traceable to an ISO 9001 certified facility. Fleet data shows that OEM studs reduce fastener‑related failures by 70%.
Preparation: Clean the tapped hole and stud threads. Apply thread locker to the end that will be permanently installed.
Installation: Screw the WG9700220004 stud into the hole using a double‑nut until fully seated. Allow thread locker to cure, then assemble components and torque nuts.
After installation, verify that the nuts achieve the specified torque and that the assembly is secure. Never reuse studs that have been removed.
Rolled threads and precise tolerances ensure a tight fit, preventing loosening under severe vibration.
The alloy steel retains its strength from -40°C to +200°C, ensuring reliable performance in all climates.
Steel contains >85% recycled content; 100% of machining scrap is recycled.
At end of life, the stud is 100% recyclable, supporting a circular economy.
Every WG9700220004 double‑end stud is laser marked with the part number for easy identification. When you order from our official distribution channel, you receive the latest production batch with consistent thread quality and corrosion protection.
