What is a bolt seal?

Bolt seals are mechanisms used to seal and secure cargo containers, such as shipping containers, trucks and trailers. These prodcuts provide tamper evidence in case of infringement. In this way bolt seals help to detect cargo theft or contamination. These security seals have a relative high breaking strength and therefore also provide an added layer of security.

A bolt seal used for securing containers must conform to the ISO 17712:2013 high security seal standard in order to be accepted by customs all around the world in ocean shipping. ISO 17712:2013 certified seals also comply with CTPAT. CTPAT, which stands for Customs Trade Partnership Against Terrorism, was started by U.S. Customs and Border Protection to strengthen international supply chains and improve United States border security.

 

How to use a bolt seal?

These security seals can be applied without the use of tools. This is how you install a bolt seal.

  1. Insert the bolt in the trailer door or container door latch hole.
  2. Align the bolt and the bolt lock such that the unique serial part number is visible on both parts.
  3. Coordinate the bolt into the locking mechanism’s hole. Make sure that it is aligned correctly and insert the bolt loosely such that misalignment is avoided.
  4. After this push the bolt in the lock until it is snaps. Push and pull the bolt seal firmly to check if the bolt security seal is closed well.

 

How to remove a bolt seal?

For removing a bolt security seal, a bolt cutter is required. You cannot open a bolt seal by hand. These seals are one time usable tamper evident seals. Hoefon Security Seals sells both electric cutters and hydraulic cutters.
