Manufactured from 35CrMo alloy steel, heat‑treated to achieve 10.9 grade, providing exceptional tensile strength and resistance to shear forces.
Rolled threads with tight tolerance ensure consistent clamping load and prevent galling during installation.
Pre‑applied microencapsulated epoxy locks the bolt in place, preventing loosening under severe vibration and shock.
Every bolt undergoes dimensional, hardness, and adhesive integrity checks to guarantee zero defects.
This glued combination bolt is a direct replacement for the following SINOTRUK Howo systems and vehicle series:
The WG9003801065 glued combination bolt is manufactured from high‑quality 35CrMo alloy steel, which is then heat‑treated to achieve the mechanical properties of grade 10.9. The bolt features a rolled thread for improved fatigue resistance and a hex flange head that distributes clamping force evenly, eliminating the need for a separate washer. The most distinctive feature is the pre‑applied microencapsulated epoxy coating on the threads. During installation, the capsules rupture and the adhesive cures, locking the bolt in place and preventing loosening from vibration. This meticulous process ensures that this critical fastening component meets or exceeds the original equipment specifications.
In heavy‑duty trucks, bolts are subjected to extreme vibration, thermal cycling, and dynamic loads. Loose fasteners can lead to component misalignment, accelerated wear, and even catastrophic failure. The WG9003801065 bolt is designed to maintain clamping force under the harshest conditions, with a breakaway torque significantly higher than standard bolts. Fleet operators who have switched to this genuine part report fewer maintenance issues and extended component life, directly impacting their bottom line.
Installation of the WG9003801065 bolt is straightforward but requires attention to detail. The bolt must be threaded into a clean, oil‑free hole to allow the adhesive to bond properly. It should be tightened to the specified torque value using a calibrated wrench; the adhesive will cure within 24 hours at room temperature. Using genuine parts ensures that the adhesive formulation is correct for the application. After installation, the joint should not be disturbed until the adhesive has fully cured.
The quality control for this bolt includes 100% inspection of critical dimensions using optical comparators and micrometers. Every bolt is also tested for hardness and tensile strength. Samples from each production batch undergo vibration testing to verify the locking performance of the adhesive. These rigorous checks guarantee that the WG9003801065 you receive will deliver the same performance and durability as the original component installed in new Howo trucks.
Environmental sustainability is considered in the production of this bolt. The steel used is sourced from mills with certified environmental management systems, and the heat treatment process uses energy‑efficient furnaces with minimal emissions. The adhesive is formulated without hazardous solvents and is fully cured within the joint, eliminating environmental release. At the end of its long service life, the bolt is fully recyclable, contributing to a circular economy. By choosing the genuine component, you are not only ensuring the reliability of your vehicle but also supporting responsible manufacturing practices.
For maintenance departments and rebuilders, the WG9003801065 bolt is available individually or as part of a fastener kit. Each bolt is packaged in a sealed polybag with a desiccant to protect the adhesive from moisture. A data sheet with actual measured dimensions and batch number is included with each bag, providing full traceability. Bulk orders receive quantity discounts and can be shipped directly to your workshop from our regional distribution centers.
Field performance data collected from over 500 Howo trucks operating in various conditions (highway, off‑road, mining) shows that this bolt has a mean time between failures (MTBF) exceeding 800,000 kilometers when properly installed. This exceptional reliability is the result of superior material selection and precise manufacturing. Many fleet managers have standardized on this genuine part for all critical fastening applications, reducing parts inventory complexity and ensuring consistent quality.
When ordering, please verify your vehicle’s application and required thread size to ensure correct fitment. The WG9003801065 bolt is specifically designed for M10 x 1.5 threads with 65 mm length. For other sizes, please consult our cross‑reference guide. Our technical team is available to answer any questions regarding compatibility, but please note that we do not provide direct contact information on this page as per our policy; instead, you may refer to the documentation included with the part or contact your local SINOTRUK dealer.
In summary, the WG9003801065 glued combination bolt represents the highest standard of quality and engineering for SINOTRUK Howo trucks. Its high‑strength alloy steel, precision threads, and integrated adhesive coating ensure secure, vibration‑proof fastening and extended component life. By choosing this genuine component, you protect your investment and keep your fleet on the road. Trust the WG9003801065 – the bolt that heavy‑duty demands.
During service, visually inspect bolts for signs of corrosion or damage. Check torque periodically on critical joints. Replace any bolt that shows thread damage.
Always replace bolts with genuine WG9003801065 when disassembling a joint. Never reuse a bolt with cured adhesive, as the locking effect may be compromised.
Only the authentic WG9003801065 bolt carries SINOTRUK’s material certification. Imitations often use low‑grade steel that lacks strength, or adhesive that fails under temperature extremes, leading to loosening and failure. The genuine part is traceable to an ISO 9001 facility, with 100% inspection. When you install this bolt, you preserve the resale value of your Howo and avoid costly downtime. Fleet operators report that using the OEM component cuts unscheduled repairs by 60%.
Preparation: Ensure threaded holes are clean, dry, and free of oil. Do not apply additional thread locker, as the pre‑applied coating is sufficient.
Torquing: Insert bolt and tighten to the specified torque value using a calibrated wrench. Do not exceed torque, as adhesive performance may be affected.
After installation, allow 24 hours for full adhesive cure before subjecting the joint to full load. Avoid disturbing the bolt during this period.
The adhesive locking feature maintains clamp load even under severe vibration, preventing loosening and joint fatigue.
The adhesive maintains its locking properties from -50°C to +150°C, ensuring reliability in all climates.
The steel contains over 90% recycled content. Production scrap is recycled into new steel, minimizing environmental footprint.
At end of life, the bolt is 100% recyclable, supporting circular economy principles and reducing landfill waste.
Every WG9003801065 bolt leaves the factory with a lot number for full traceability. When you order from our official warehouse, you receive the latest production batch with optimized adhesive formulation – a detail many suppliers ignore. Pair the bolt with genuine SINOTRUK Howo nuts and washers for a 100% match.
