OEM direct replacement • High-strength alloy steel • Precision-rolled threads • Corrosion-resistant finish • Reliable clamping force
The Q150B1085 is a hex head bolt designed for use in critical bolted connections throughout SINOTRUK Howo A7 and T7H series trucks. This fastener is used in chassis frames, suspension linkages, engine mounts, transmission housings, and other structural assemblies where high clamping force and reliable torque retention are essential. Its OEM-grade construction matches the original bolt’s dimensions, thread class, and material properties, ensuring perfect fitment and reliable performance.
The bolt is manufactured from high-quality alloy steel (typically 40Cr or equivalent) with controlled heat treatment to achieve a tensile strength grade of 10.9 or higher, providing the high clamping force required for heavy-duty chassis applications. The threads are precision-rolled to ensure consistent thread form, surface finish, and dimensional accuracy, reducing the risk of galling and ensuring smooth installation.
The Q150B1085 features a standard hex head that allows for secure engagement with standard wrenches or sockets, enabling accurate torque application. The bolt is finished with a corrosion-resistant coating, such as zinc plating or black oxide, which protects against rust and chemical attack from road salts, moisture, and automotive fluids.
The bolt’s precise thread fit and consistent geometry ensure that it provides the correct clamping force when torqued to the specified value. Its robust construction and exact dimensions contribute to joint integrity, vibration resistance, and extended service life of the assembled components.
Common symptoms of a failing fastener include loosening of the joint, visible corrosion or damage to the threads, and loss of clamping force. Replacing a worn or damaged bolt with the Q150B1085 restores proper joint integrity and protects the chassis from costly damage.
Whether you’re performing a major chassis overhaul or replacing a single fastener, the Q150B1085 Hex Head Bolt offers the quality, precision, and reliability that SINOTRUK Howo professionals demand.
The Q150B1085 hex head bolt is specifically designed for SINOTRUK Howo A7 and T7H series trucks, as well as other heavy-duty chassis that require an M10×1.25×85 mm fastener of this strength grade. It is used in critical bolted joints throughout the vehicle, including chassis frame connections, suspension mounting points, engine and transmission mounts, and structural crossmembers.
This bolt serves as a direct replacement for the original factory fastener and is compatible with all chassis assemblies that use this specific thread and length.
This fastener is essential for applications involving heavy loads, extreme vibration, and demanding operating conditions, such as long-haul transport, construction, and mining. In these environments, the bolt is subjected to high tensile and shear loads.
The Q150B1085 is engineered to withstand these harsh conditions, providing consistent clamping force and joint integrity. When replacing a bolt, it is important to inspect the mating threads and the joint surfaces for wear or damage.
The Q150B1085 is designed to work with the factory-spec hardware, ensuring proper fit and torque characteristics. Replacing worn bolts with new OEM units is recommended for optimal joint integrity.
For fleets with multiple HOWO trucks, this bolt standardizes fasteners, simplifying parts inventory and ensuring the correct hardware is available for maintenance or repairs. Always verify the thread size and length on your specific application, though the Q150B1085 is the standard bolt for numerous chassis connections in A7 and T7H models.
Installing the Q150B1085 hex head bolt requires careful attention to thread cleanliness, proper torque application, and the use of appropriate tools.
This work should be performed by a qualified technician with access to a calibrated torque wrench and the correct socket size. Begin by ensuring the threaded hole is clean and free from debris, old thread-locking compound, or damage.
Use a thread chaser if necessary to restore the threads. Apply a thread-locking compound (medium strength, such as Loctite 243) to the fastener threads if specified in the service manual, and lubricate the threads with clean oil if torque values are specified for lubricated conditions.
Insert the new Q150B1085 bolt into the threaded hole and hand-tighten until the head contacts the mating surface. Use a torque wrench with the correct socket to tighten the bolt to the manufacturer’s specified torque value (typically 60-80 Nm for M10 grade 10.9 bolts).
Apply torque in a smooth, controlled manner to achieve the correct clamping force. For critical joints, use a torque-angle method as specified in the service manual.
For maintenance, periodically inspect critical bolted joints for signs of loosening, corrosion, or thread damage. The Q150B1085 is designed for long service life, but proper torque verification during routine maintenance is essential to ensure joint integrity.
Always replace fasteners that show signs of damage or that have been loosened and retightened multiple times. Use new Q150B1085 bolts for critical joints to maintain reliable clamping force.
The Q150B1085 hex head bolt is manufactured in an ISO 9001-certified facility using advanced cold-forming, thread-rolling, and heat-treatment processes.
The alloy steel is sourced from certified mills and undergoes chemical analysis to confirm its composition and mechanical properties. Each bolt is produced to precise dimensional tolerances to ensure consistent fit and performance.
Every bolt undergoes a series of quality checks, including dimensional verification (head diameter, head height, thread major/minor diameter, and length), thread inspection, and hardness testing.
The hex head is inspected for proper size and shape, and the surface finish is checked for defects. Random samples from each batch are subjected to tensile testing, torque retention testing, and fatigue testing to confirm long-term reliability.
We back the Q150B1085 with a comprehensive warranty against material and workmanship defects. Our rigorous quality control ensures that every bolt delivers the same fit, strength, and reliability as the original factory part, giving you confidence in your chassis’s fastening integrity.
