In the demanding environment of heavy-duty trucking, every fastener must perform flawlessly to ensure structural integrity and safety. The Q33410 Locking Metal Hexagon Nut, Style (Vice), is a specialized OEM component designed to meet this critical need. As an indispensable part of any reliable Foton truck parts inventory, this nut provides a secure, permanent lock that resists loosening under extreme vibration and dynamic loads. This introduction outlines the engineering excellence behind part number Q33410, highlighting its role in maintaining joint security and preventing costly failures in FOTON commercial vehicles.
The Q33410 Locking Metal Hexagon Nut, Style (Vice), is a high-strength, self-locking fastener manufactured to FOTON’s precise OEM specifications. Unlike standard nuts, it incorporates a built-in locking feature—typically a nylon (polyamide) insert or a de-formed top section—that creates a prevailing torque against the mating bolt thread. This friction lock prevents the nut from rotating loose due to vibration, thermal cycling, or dynamic loads, making it a “one-time use” or permanent fastener in critical applications. Its hexagonal shape allows for application with standard wrenches and sockets, while the “Vice” style denotes its robust, non-slip gripping capability.
This component is essential for safety-critical assemblies where joint integrity is paramount. The locking mechanism of part Q33410 ensures that the clamp load is maintained throughout the service life of the vehicle, preventing catastrophic failures in systems like suspension, steering, driveline, and engine mounts. Made from hardened steel and often coated for corrosion resistance, it is designed to withstand the harsh operating conditions of commercial trucks.
Integrated Locking Mechanism: Features a nylon insert or all-metal deformed thread that creates a prevailing torque, ensuring the nut stays securely fastened without the need for external lock washers or adhesives.
Exceptional Vibration Resistance: Specifically engineered to resist self-loosening under continuous vibration and shock loads, a common challenge in truck and heavy equipment operations.
High Clamp Load Retention: Maintains the initial bolt preload over time, which is critical for the longevity and reliability of the fastened joint, especially for part Q33410.
Corrosion Protection: Often finished with zinc plating, galvanization, or other coatings to provide excellent resistance to rust and environmental degradation in underbody and engine bay applications.
Wide Temperature Tolerance: The locking element (especially metal types) is designed to perform reliably across a broad temperature range, maintaining locking force in both cold and hot operating conditions.
Reusability Considerations: While some locking nuts are designed for single use, others may allow limited re-torquing. Always refer to FOTON service guidelines for part Q33410.

The Q33410 Locking Nut is specified for use in numerous high-vibration, safety-critical locations on a FOTON truck. Its primary role is to secure bolted joints where traditional nuts might loosen over time. Common application points include securing wheel bearing hub assemblies, fastening U-bolts on leaf springs, mounting shock absorbers and stabilizer bar links, and assembling critical engine and transmission components such as flywheel housing bolts and driveline flanges.
Specific System Applications:
• Suspension & Chassis: Securing control arm bolts, track bar mounts, and steering linkage pivot points.
• Wheel End: Used on axle spindle nuts to maintain wheel bearing preload and prevent wheel detachment.
• Driveline: Fastening propeller shaft companion flanges and center bearing supports.
• Engine & Transmission: Mounting engine brackets, exhaust manifold studs, and bell housing bolts.
• Braking System: Securing caliper mounting bolts and air brake chamber brackets.
Compatibility for part Q33410 spans across various FOTON models, including the Auman heavy-duty series, Tunland light trucks, and Forland mid-duty trucks. It is vital to use this specific locking nut where indicated in the service manual to ensure the joint is equipped with the correct vibration-resistant fastener.
Correct installation is critical for the locking nut to perform as intended. The threads of both the bolt and the nut should be clean, dry, and free of debris or old thread-locking compound. For nuts with a nylon insert, it is generally recommended to run the nut down until it seats by hand, then use a torque wrench to achieve the final torque value. The nylon insert creates drag, so the torque required to achieve proper clamp load may be slightly higher than for a standard nut.
