Product Introduction

This high-strength wheel bolt and nut assembly is a critical safety component for heavy-duty truck front wheel-ends, engineered to withstand extreme dynamic loads, vibration, and thermal stress from braking. Its precision design ensures a secure, vibration-resistant wheel attachment.

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 corrosion protection.

• Design: A flanged wheel bolt paired with a heavy-duty hexagonal nut and integrated washer. The flanged head distributes clamping force evenly, 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 under extreme loads.

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

• Corrosion Protection: The zinc-plated finish resists rust and corrosion, ensuring reliable performance in harsh operating environments.

Durability

• High-tensile alloy steel resists stretching, shearing, and fatigue under continuous heavy loads and braking forces.

• The corrosion-resistant coating maintains the bolt and nut’s structural integrity, extending service life.

Core Function

1. Wheel Securement: Fastens the front 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

What trucks does the WG9100410212 front wheel bolt fit?

This bolt with nut is specifically designed for Sinotruk Sitrak series trucks. It mounts on the front axle wheel hub and is interchangeable with the original OEM part number WG9100410212. If you’re unsure about compatibility with a specific Sitrak model, feel free to send us your VIN or chassis number for verification.

Is this front wheel bolt sold as a complete set with the nut?

Yes, absolutely. Each WG9100410212 unit ships as a matched bolt-and-nut assembly. This ensures proper thread engagement and correct clamping force — you won’t need to source the nut separately.

What material is the WG9100410212 wheel bolt made from?

It’s manufactured from high-strength alloy steel, then surface-treated with an anti-corrosion coating (typically zinc plating or phosphating). This combination provides excellent tensile strength, fatigue resistance, and protection against environmental corrosion.

How do I know the quality matches OEM standards?

Every production batch goes through strict quality control — including hardness testing, thread gauge inspection, and dimensional verification. The bolt meets GB (Chinese National Standard) specifications equivalent to the original Sinotruk factory part. We can provide test reports upon request.

What is the recommended torque for installing this front wheel bolt?

We recommend following the torque specification listed in your Sinotruk Sitrak service manual for the front wheel hub bolts. Typically, front wheel bolts on heavy-duty trucks require torquing in a star pattern to ensure even clamping. If you need guidance, our technical team can assist.

Can I order a small quantity for testing before placing a bulk order?

Of course. We understand that procurement managers often need to validate parts before committing to large volumes. Contact us to discuss sample quantities and pricing — we’re happy to support your evaluation process.
