Product Introduction

This rear wheel bolt and nut assembly is a heavy-duty, precision-engineered fastener, manufactured from high-strength alloy steel to withstand the extreme loads, vibrations, and stresses encountered during heavy-duty operation. The bolt features a knurled shank for a secure press-fit into the wheel hub, a precision-threaded end for the nut, and a flanged head to distribute clamping forces evenly. The matching nut is designed with a self-locking feature to prevent loosening under dynamic loads. Both components undergo rigorous heat treatment and surface finishing processes, including black oxide coating, to provide exceptional strength, durability, and resistance to corrosion and fatigue.

Core Function

• Secures the rear wheel to the wheel hub and axle flange, providing a rigid and reliable connection that withstands the vertical, lateral, and torsional loads generated during operation.

• The knurled shank ensures a tight, non-rotating fit within the wheel hub, preventing relative movement and maintaining wheel alignment.

• The self-locking nut maintains consistent clamping force, preventing loosening under vibration and dynamic loads, and ensuring safe and reliable operation.

• The high-strength alloy steel construction resists shear and tensile failure, providing exceptional durability and extended service life in heavy-duty applications.

• Directly interchangeable with the original factory part, ensuring a precise fit and consistent performance within the rear wheel hub assembly.

Key Features and Benefits of the 199012340123 Rear Wheel Bolt With Nut

Choosing the right rear wheel bolt is not just a matter of fit—it directly impacts vehicle safety, maintenance costs, and uptime. Here is why procurement managers across Africa, the Middle East, Southeast Asia, and Latin America trust this particular fastener:

• OEM-Grade Material Composition: Forged from high-strength alloy steel, this bolt withstands extreme torque, vibration, and heavy axle loads without deformation or fatigue failure.
• Precision Thread Engineering: The threads are rolled (not cut), which results in a smoother surface finish, tighter mating, and superior resistance to loosening over time.
• Corrosion-Resistant Surface Treatment: A phosphate or zinc-plated coating protects against rust and environmental degradation, extending service life even in humid or salt-laden operating environments.
• Complete Bolt-and-Nut Set: Each unit ships as a matched pair, eliminating compatibility guesswork and reducing assembly time during wheel installation or rotation.
• Direct Dimensional Replacement: Engineered to the exact OEM dimensions of part number 199012340123, so it drops right into existing hub bolt holes with zero modification.
• Consistent Clamping Force: Maintains specified preload across temperature cycles and repeated braking events, which is essential for preventing wheel separation incidents.

In short, this rear wheel bolt with nut does one job—and it does it exceptionally well: it keeps your rear wheels firmly attached to the axle hub, mile after mile.

Application Scenarios for Sinotruk Rear Wheel Bolt 199012340123

Understanding when and where this fastener is needed helps you plan procurement more effectively. Here are the most common application scenarios:

• Routine Wheel Maintenance: Every time rear wheels are removed for brake inspection, tire replacement, or rotation, these bolts should be inspected and replaced if any signs of thread damage or elongation appear.
• Wear and Aging Replacement: Over thousands of kilometers, constant vibration and thermal cycling gradually weaken fastener integrity. Proactive replacement at scheduled intervals prevents unexpected failures on the road.
• Post-Incident Repair: After any wheel-related incident—such as a puncture repair, hub damage, or collision—replacing all rear wheel bolts as a set is standard safety practice.
• Fleet Overhaul Programs: When refurbishing or reconditioning older Sinotruk HOWO trucks for resale or continued service, fresh rear wheel bolts restore factory-level wheel retention security.
• New Vehicle Assembly: Workshops and assemblers building or converting Sinotruk-based special vehicles rely on this exact part number for rear axle wheel attachment.

This bolt is specifically designed for Sinotruk heavy-duty vehicles, including HOWO A7, HOWO T7H, and HOWO T5G models equipped with standard rear axle hubs. If you are managing a mixed fleet, our team can help you cross-reference compatibility. Simply contact us with your vehicle chassis number.

Frequently Asked Questions – Rear Wheel Bolt With Nut 199012340123

What vehicles does the 199012340123 rear wheel bolt fit?

This bolt-and-nut assembly is designed specifically for Sinotruk HOWO heavy-duty trucks, including popular models such as the HOWO A7, T7H, and T5G. It mounts on the rear axle hub to secure the wheel rim. If you are unsure about fitment for your particular model year or axle variant, feel free to send us your chassis number and we will confirm compatibility.

Is this bolt sold individually or as a set?

Each unit includes one bolt plus one matching nut as a complete pair. For full wheel replacement, you would typically need a set of 10 bolt-nut pairs per wheel (rear dual wheels may require 10 per hub face). We recommend ordering in complete sets to ensure uniform clamping performance.

What grade of steel is used in this fastener?

The Rear Wheel Bolt With Nut 199012340123 is manufactured from high-strength alloy steel meeting Grade 10.9 (or equivalent) standards. This grade delivers excellent tensile strength and fatigue resistance, which is essential for rear axle wheel bolts that endure constant dynamic loads.

How often should rear wheel bolts be replaced?

As a general best practice, rear wheel bolts should be inspected during every tire change or brake service. Replace them immediately if you observe thread damage, corrosion, visible stretching, or inconsistent torque readings. Many fleet operators also adopt a preventive replacement interval aligned with major service milestones—typically every 200,000–300,000 km depending on operating conditions.

Can I reuse the nut after removing the bolt?

While some nuts can technically be reused if they show no damage, we strongly recommend installing a fresh nut each time the bolt is removed. Repeated tightening cycles can reduce the nut’s prevailing torque, which may compromise clamping force and increase the risk of loosening under vibration.

Do you offer quality inspection reports with each shipment?

Yes. Upon request, we can provide dimensional inspection reports, material certificates, and hardness test results for your order. This documentation supports your own incoming quality procedures and helps satisfy end-customer requirements.
