The Hex bolt with serrated flange M14*1.5 is a heavy‑duty fastener designed to secure the Insulation plate to the cab structure. Its serrated flange provides a mechanical locking action that resists loosening under vibration, ensuring that the insulation remains firmly in place. The bolt is manufactured from high‑tensile steel with a corrosion‑resistant zinc‑nickel coating.
This Hex bolt with serrated flange M14*1.5 features a fine‑pitch thread (1.5mm) that offers precise torque control and excellent holding power. The flange distributes the load evenly, preventing damage to the Insulation plate and the cab surface. The hex head allows for easy tightening with standard sockets, simplifying installation and maintenance.
The Hex bolt with serrated flange M14*1.5 is a vital component of the Insulation board device, providing the secure fastening needed to keep the insulation plate in place. Its durable construction and vibration‑resistant design ensure long‑term reliability, making it an essential part of the kit.
The Hex flange nut with teeth M14*1.5 is the matching lock nut for the serrated flange bolt, providing a secure and vibration‑proof connection. Its internal teeth bite into the bolt threads, creating a prevailing torque that prevents loosening. The flange distributes the clamping load, protecting the Insulation plate and the surrounding structure.
This Hex flange nut with teeth M14*1.5 is manufactured from the same high‑grade steel and coated for corrosion resistance. Its standard hex shape allows for easy tightening with a wrench, and the flange eliminates the need for a separate washer. The nut is designed to work in conjunction with the serrated flange bolt, creating a robust fastening system that maintains its integrity under extreme conditions.
The Hex flange nut with teeth M14*1.5 is an essential component of the Insulation board device, completing the fastening system that secures the insulation plate. Its reliable locking action ensures that the insulation remains securely attached, providing long‑lasting protection against heat and noise.

The Insulation board device significantly reduces heat transfer from the engine and exhaust, keeping the cab cooler and more comfortable. It also absorbs road and engine noise, creating a quieter cabin that reduces driver fatigue and improves concentration.
The Insulation plate is die‑cut to match the exact contours of the HOWO 4X2 cab, ensuring a perfect fit with no gaps. The included fasteners are of the same grade and specification as the original parts, guaranteeing secure and reliable installation.
The Insulation board device includes not only the insulation plate but also all necessary bolts and nuts for a complete installation. This eliminates the need to source separate fasteners, saving time and ensuring that you have the correct hardware for the job.
This Insulation board device is designed for all HOWO 4X2 models and is backed by our worldwide distribution network. Expert technical support is available to assist with any installation or compatibility questions.
The Insulation board device is the result of extensive research and development aimed at optimizing the thermal and acoustic environment of the HOWO 4X2 cab. The insulation plate is constructed from a multi‑layer composite that includes a sound‑absorbing foam core and a heat‑reflective metallic skin. This combination provides a high level of sound attenuation across a wide frequency range, effectively reducing engine drone, tire noise, and wind roar.
The heat‑reflective foil on the Insulation plate reflects up to 95% of radiant heat, keeping the cab floor and firewall significantly cooler. This reduces the load on the air conditioning system, improving fuel efficiency and driver comfort. The plate is also designed to be lightweight, adding minimal weight to the vehicle while providing maximum protection.
The fastening system – comprising the serrated flange bolt and toothed flange nut – is engineered to maintain clamping force under extreme vibration and thermal expansion. The serrations on the bolt head and the teeth on the nut provide a mechanical interlock that prevents loosening, ensuring that the Insulation plate remains securely attached over millions of miles. This attention to detail ensures that the Insulation board device delivers consistent performance throughout the vehicle’s service life.
Each Insulation board device component undergoes rigorous quality inspections to ensure it meets the highest standards of performance and durability. The Insulation plate is tested for thermal conductivity, sound absorption coefficient, and dimensional accuracy. The fasteners are sampled for tensile strength, hardness, and thread fit, and their corrosion resistance is verified through salt spray testing.
We also perform installation validation tests on complete kits, mounting the insulation plate on a test fixture and subjecting it to vibration and thermal cycling to simulate real‑world conditions. These tests confirm that the Insulation board device remains securely attached and maintains its insulating properties over time. The results guarantee that the kit delivers the promised reduction in heat and noise.
Our quality management system is certified to IATF 16949, and each kit is traceable to its production batch, ensuring full accountability and rapid response to any quality concerns.
Investing in a genuine Insulation board device improves driver comfort and reduces fatigue, leading to better concentration and safer driving. A cooler cab also reduces the workload on the air conditioning system, which can lower fuel consumption and extend the life of the AC components. These operational benefits translate directly into cost savings over the vehicle’s lifetime.
For fleet operators, the Insulation board device helps maintain a consistent cabin environment across the fleet, which can improve driver retention and satisfaction. The durable construction of the insulation plate means it will not sag, degrade, or become less effective over time, reducing the need for replacement and minimizing maintenance costs.
The Insulation board device is a cost‑effective upgrade that pays for itself through improved driver well‑being, reduced HVAC usage, and prolonged vehicle interior life. It is a smart investment for any fleet looking to enhance both productivity and driver comfort.
