Bolt seals are a type of high-security, single-use, tamper-evident seal. Made from high-hardness alloy, they offer a secure lock and high tensile strength, making them suitable for applications such as shipping containers, chemical tanker trucks, and storage units. Proper installation is crucial for the seal to effectively provide tamper evidence and traceability.
If you are unsure of the correct installation steps, please read the detailed tutorial below.
Step 1
Before installation, the most important step is to ensure the seal’s packaging is intact. Verify that the unique serial numbers on the lock body and the bolt shaft match perfectly, and confirm that the anti-counterfeiting marks and traceability codes on the surface are clearly legible. It is also advisable to inspect the lock body and locking hole for any signs of damage.
Step 2
Align the locking points of the equipment or container to be sealed. Insert the bolt shaft through the locking holes, ensuring it passes completely through all the holes. Leave about 1–2 cm of the shaft protruding on the other side to facilitate the final locking step. When dealing with heavy-duty applications like shipping containers or tanker trucks, ensure the locking points are properly aligned and the shaft slides in smoothly without obstruction; avoid forcing the shaft in, as this could cause deformation.
Step 3
Align the protruding end of the bolt shaft with the locking hole on the lock body. Push it in firmly and vertically until you hear a distinct “click” indicating it is locked. Gently pull the lock body outward to confirm it is secure and cannot be loosened. Note: Do not apply force at an angle, as this could bend the bolt shaft, resulting in an incomplete lock and creating a potential security vulnerability.
Step 4
Once locked, an important final step is to photograph the seal to document its appearance, serial number, installation location, and time, and to enter this information into your traceability management system.
