The Battery Box Fixing Bracket is a robust, precision‑stamped steel component that serves as the primary mounting support for the battery box. It is designed to accommodate one side on a flat chassis plane and the other on a 4.5° bend zone, ensuring a secure fit on the C7H frame. The bracket features multiple pre‑drilled holes for the attachment bolts and is coated with an anti‑corrosion finish for long‑term durability.
The Hexagon Flange Bolt with Serrations M14*1.5 is a high‑strength fastener used to secure the battery box bracket to the chassis frame. Its integrated flange eliminates the need for a separate washer, while the serrations under the head provide a locking action that resists loosening from vibration. Two different part numbers (ZQ1811435TF6 and ZQ1811450TF6) offer variant lengths for different mounting depths, ensuring compatibility with varying frame thicknesses.
The Hexagon Flange Nut with Serrations M14*1.5 is the matching fastener for the flange bolt, providing a secure and vibration‑resistant connection. Its flanged design distributes clamping load evenly across the bracket surface, and the internal serrations bite into the bolt threads to prevent loosening, ensuring the Battery Box Installation remains intact under all driving conditions.
Our Battery Box Installation kit is manufactured to Sinotruk’s original specifications, ensuring exact alignment with the C7H chassis mounting points, including the 4.5° bend zone. The bracket and fasteners are designed to work together seamlessly.
The serrated flange bolts and nuts provide superior locking performance, preventing loosening even under severe road vibration. This ensures that the battery box remains securely mounted throughout the vehicle’s service life.
We supply all required bolts and nuts in the correct quantities and sizes, including both length variants for the flange bolts. No additional hardware is needed, simplifying the installation process.
All components feature a zinc‑plated or anti‑corrosion coating, protecting them against moisture, road salt, and chemical exposure, ensuring long‑term reliability in harsh operating environments.
The Battery Box Installation kit is a critical component for the Sitrak C7H, providing a robust and reliable mounting solution for the vehicle’s battery box. The kit is specifically engineered to accommodate the unique chassis geometry where one side of the bracket mounts on a flat surface and the other on a 4.5° angled zone.
The bracket is made from high‑strength steel with a precision‑formed shape that matches the chassis contour. Its design ensures that the battery box is held firmly in place, preventing movement that could lead to cable damage or electrical faults. The bracket’s anti‑corrosion coating provides long‑lasting protection against the elements.
The Hexagon Flange Bolts with Serrations are available in two lengths (35mm and 50mm) to suit different frame thicknesses and mounting positions. The integrated serrations under the bolt head act as a locking mechanism, preventing the bolts from backing out due to vibration, which is a common issue with standard bolts.
The Hexagon Flange Nuts with Serrations are the perfect complement to the bolts, providing a secure, self‑locking connection. Their flanged design eliminates the need for separate washers, simplifying assembly and reducing the risk of lost parts.
Installation of the Battery Box Installation kit is straightforward and can be completed with standard hand tools. The bracket is positioned on the chassis frame, and the bolts are inserted through the bracket holes and into the frame, with the nuts tightened to the specified torque.
We recommend using a torque wrench to ensure correct clamping force, which is critical for maintaining the integrity of the serrated locking mechanism. Over‑tightening can strip the serrations, while under‑tightening can lead to loosening.
The Battery Box Installation kit is designed for both original assembly and replacement applications. If the original bracket or fasteners are corroded or damaged, replacing them with our genuine kit restores the battery box’s security and electrical reliability.
For fleet operators, standardising on this genuine Battery Box Installation kit simplifies spare parts management and ensures consistent quality across all trucks. The kit’s durability reduces the frequency of replacements and lowers maintenance costs.
The serrated flange bolts and nuts conform to ISO 10511 and ISO 10512 standards, ensuring high‑quality thread engagement and clamping performance. They are manufactured from grade 10.9 steel for maximum strength.
We advise inspecting the battery box mounting periodically, especially after off‑road operation or heavy impacts. Loose or damaged fasteners should be replaced immediately to prevent battery box movement and potential cable chafing.
The bracket is designed to accommodate both standard and maintenance‑free batteries, with ample space for cable routing and terminal access. Its open design allows for easy cleaning and inspection.
Our Battery Box Installation kit is backed by a 12‑month warranty against manufacturing defects. If any component fails under normal use, we will replace it free of charge. Our technical support team is available to assist with any installation queries.
