The Shacman H3000 Reverse Peak Sound system combines a robust audible warning device with the necessary high‑strength fasteners to ensure reliable operation in heavy‑duty environments. This genuine OEM solution includes the Reverse Buzzer, a powerful acoustic alarm that alerts pedestrians and other vehicles when the truck is backing up, along with the Hexagon Flange Bolt and the All Metal Hexagonal Flange Locking Nut – designed to secure the buzzer and other components firmly against vibration. Engineered specifically for the Shacman H3000 series, this assembly guarantees a perfect fit, exceptional durability, and consistent performance in the most demanding conditions.
The Shacman H3000 Reverse Peak Sound assembly is not just about making noise; it is about ensuring that every reverse maneuver is conducted with maximum safety. The Shacman H3000 Reverse Peak Sound buzzer produces a distinctive, penetrating tone that cuts through ambient noise, while the flange bolt and locking nut provide a secure, tamper‑proof mounting solution. Together, they form a dependable system that withstands the severe vibration, temperature extremes, and moisture common in truck operations. By choosing genuine Shacman parts, you maintain the integrity of your vehicle’s safety systems and protect your investment for years to come.
The Shacman H3000 Reverse Peak Sound Hexagon Flange Bolt is a high‑strength fastener featuring an integrated flange that acts as a built‑in washer, distributing clamping load evenly and preventing surface damage. Its six‑sided head provides excellent torque transmission, and the flange eliminates the need for a separate washer, simplifying installation. Made from galvanized steel, it offers superior corrosion resistance and is designed to withstand the high vibration levels of a heavy‑duty truck. This bolt is used to secure the Reverse Buzzer to its mounting bracket or chassis, ensuring it remains firmly in place.
The Reverse Buzzer is an electro‑acoustic transducer that emits a loud, directional warning sound when the vehicle is shifted into reverse gear. It produces a pulsed tone in the range of 85‑100 dB at 1 meter, ensuring clear audibility even in noisy construction or urban environments. The buzzer is housed in a weather‑proof IP67‑rated enclosure, protecting it from dust, water, and road debris. Its compact design and standard mounting pattern allow for easy retrofit or replacement, and its low current draw (≤0.5A) makes it suitable for 24V systems.
This all‑metal locking nut features a hexagonal flange design with a built‑in serrated face or distorted thread locking element, providing a secure, vibration‑resistant fastening. The flange serves as a washer to protect the mounting surface, while the locking mechanism prevents loosening under dynamic loading. Manufactured from high‑strength steel with a zinc‑plated finish, it offers excellent corrosion protection and long service life. It is used in conjunction with the Hexagon Flange Bolt to create a robust, tamper‑proof assembly for the Reverse Buzzer or other chassis components.
The combination of the Reverse Buzzer and the high‑quality fasteners creates a complete safety package. The buzzer alerts nearby personnel and drivers, while the bolted connection ensures the device stays mounted even on rough terrain, preventing loss of function or detachment that could compromise safety.
The Hexagon Flange Bolt and the All Metal Hexagonal Flange Locking Nut are perfectly matched in thread size (M6) and pitch, making assembly straightforward. No additional washers are needed, reducing parts count and installation time. The buzzer comes with pre‑wired leads for quick electrical connection to the reverse light circuit.

Our Shacman H3000 Reverse Peak Sound components are 100% genuine OEM, guaranteeing the exact fit, electrical characteristics, and acoustic output of the original equipment. The Reverse Buzzer is calibrated to meet Shacman’s safety standards, and the fasteners are manufactured to the precise thread and strength specifications. This ensures that your safety system performs reliably and maintains the vehicle’s factory warranty.
The Shacman H3000 Reverse Peak Sound set is designed for rapid installation. The buzzer uses standard two‑wire connections, and the bolt and nut are sized for the existing mounting holes. No drilling or modification is required – simply replace the old unit and secure it with the new hardware. This minimizes downtime and gets your truck back to work quickly.
Safety is our priority. The Reverse Buzzer produces a clear, attention‑grabbing sound that meets or exceeds regulatory requirements for warning devices. The fasteners are corrosion‑resistant and feature locking elements that prevent loosening due to vibration. This ensures that your warning system remains operational and secure throughout the life of the vehicle, reducing the risk of accidents and liability.
We maintain a comprehensive inventory of the Shacman H3000 Reverse Peak Sound components, ensuring fast shipping and support for your maintenance needs. Our competitive pricing and global logistics make it easy to keep spare parts on hand. With our expert team, you can trust that you are getting the right parts and the right advice to keep your Shacman H3000 operating safely.
The Reverse Buzzer is typically mounted on the rear crossmember or under the chassis, facing rearward to maximize sound projection. The Hexagon Flange Bolt and All Metal Hexagonal Flange Locking Nut are used to secure it to the bracket. Before installation, ensure the mounting surface is clean and free of debris. Apply a small amount of anti‑seize compound to the bolt threads to prevent galling and facilitate future removal.
Electrical connection is straightforward: the buzzer’s positive lead (typically red) should be connected to the reverse light circuit, and the negative lead (black) to a good chassis ground. The buzzer is polarized, so incorrect polarity will result in no sound. Always consult the vehicle’s wiring diagram and test the circuit with a multimeter before final connection.
After installation, verify the buzzer’s operation by shifting into reverse with the parking brake engaged (ensure the area is clear). The sound should be clearly audible from a distance of at least 10 meters. If the sound is weak or absent, check voltage (should be 24V) and ground continuity. The Hexagon Flange Bolt and nut should be torqued to 25‑30 Nm to ensure a secure, vibration‑proof fastening.
Regular maintenance of the Reverse Buzzer includes checking for dirt buildup, which can muffle the sound, and inspecting the mounting bolts for tightness. The All Metal Hexagonal Flange Locking Nut maintains its locking action even after repeated removal, but if it becomes loose, replace it with a new one. Our genuine components are designed for long life, but periodic inspection is recommended for optimal safety.
For trucks operating in extremely noisy environments (e.g., construction sites), consider mounting an additional buzzer on the opposite side for 360° coverage. The Shacman H3000 Reverse Peak Sound system can be expanded with multiple buzzers, each driven by its own circuit, as long as the total current does not exceed the relay or switch capacity. Our genuine parts are compatible with such upgrades.
The Reverse Buzzer is also available as a standalone replacement for those who already have suitable mounting hardware. However, for a complete and reliable installation, we recommend the full kit including the Hexagon Flange Bolt and the locking nut. This ensures that the mounting strength matches the OEM design, avoiding premature failure due to mismatched fasteners.
For fleet operators, standardizing on the Shacman H3000 Reverse Peak Sound across all vehicles simplifies parts inventory and ensures consistent warning signals. Drivers become familiar with the same audible tone, reducing confusion. Our genuine parts are backed by a warranty and our technical support, giving you peace of mind that your fleet’s safety is in good hands.
If you are replacing an existing buzzer, note the orientation of the old unit – the sound outlet should face the rear of the vehicle to direct the sound where it is most needed. The Hexagon Flange Bolt is inserted from the outside and the locking nut tightened from the back, ensuring a flush fit. Always use a torque wrench to prevent over‑tightening, which could strip the threads or damage the buzzer housing.
