Product Introduction

This high-strength wheel bolt and nut assembly is a critical safety component for heavy-duty truck rear wheel-ends. It is engineered to withstand extreme dynamic loads, vibration, and thermal stress from braking, ensuring a secure, vibration-resistant wheel attachment under all operating conditions.

Structure & Material

• Material: High-tensile alloy steel (10.9 grade), heat-treated for exceptional tensile strength and fatigue resistance. The finish is a rainbow zinc plating for superior corrosion protection.

• Design: A flanged wheel bolt paired with a heavy-duty hexagonal nut and integrated washer. The flanged head distributes clamping force evenly across the wheel hub, while the coarse thread ensures quick, secure installation.

Performance

• High Clamping Force: The 10.9-grade alloy steel delivers a high preload to keep the wheel securely fastened, even under heavy loads and aggressive braking.

• Vibration Resistance: The flanged design and precision thread ensure the assembly remains tight, preventing loosening due to road vibration and torsional forces.

Durability

• High-tensile alloy steel resists stretching, shearing, and fatigue under continuous heavy loads and brake-induced thermal stress.

Core Function

1. Wheel Securement: Fastens the rear wheel rim and brake drum to the wheel hub flange.

2. Load Transfer: Transfers dynamic loads (acceleration, braking, cornering) between the wheel and hub.

3. Safety Assurance: Maintains a secure wheel connection to prevent accidents from wheel detachment.

Frequently Asked Questions (FAQ)

Is the 810W45501-0174 rear wheel bolt with nut an original Sinotruk part?

This part is manufactured to OEM-equivalent specifications, meaning it matches the original Sinotruk Sitrak part in dimensions, material grade, and performance. It is produced under strict quality control to ensure a perfect fit and reliable service life on your Sitrak truck.

What is the recommended torque value for installing this rear wheel bolt?

You should always follow the torque specification listed in your Sinotruk Sitrak service manual for the rear wheel hub bolts. Typically, rear wheel bolts on heavy-duty trucks require high torque values applied in a star pattern to ensure even clamping. Using a calibrated torque wrench is essential to avoid under-tightening or over-tightening.

Can I use this bolt on other Sinotruk models besides Sitrak?

The 810W45501-0174 is specifically designed for the Sitrak platform. While some Sinotruk models share similar rear axle designs, we strongly recommend verifying the part number against your vehicle’s parts catalog before ordering. If you need rear wheel bolts for HOWO or other Sinotruk series, feel free to inquire — we carry a full range.

How do I know when to replace my rear wheel bolts?

Inspect your rear wheel bolts during every routine maintenance interval. Replace them immediately if you notice thread damage, visible cracks, elongation, corrosion that compromises the thread engagement, or if the bolt has been over-torqued. Reusing stretched or damaged bolts puts wheel retention at serious risk.

Does the set include both the bolt and the nut?

Yes. Each unit of part number 810W45501-0174 includes one rear wheel bolt paired with its matching nut, supplied as a complete set ready for installation.
