What exactly is a bolt seal?

A bolt seal is a two-part metal locking device complete with a unique serial number laser printed on the heavy-duty plastic casing. They fit through the handle of the container or trailer, the pin pushing into the body of the bolt seal and then the plastic cap is fitted. The cap is designed so that it can be pushed on easily by hand but not removed after. The serial number can be recorded and once installed, it is impossible to open it without breaking the seal, thus ensuring that goods arrive with nothing taken out or indeed added to along their journey.

The idea is simple: what you put inside the cargo remains there unless the seal has been broken, avoiding nasty surprises at the end destination. An Operations Manager will usually be responsible for their use and keeping track of the serial numbers. For recommendations and more detailed specifications of use,

These high-security seals are made from stronger metal than their standard counterparts, which are generally aluminium or zinc alloy. The stainless steel and high-grade ABS plastic make high security variants even harder to cut through and thus ideal for high-end merchandise such as jewellery, designer goods, or electronics, for example. In addition, they come with tamper indicators so that you are alerted to any attempt to gain entry. If you are unsure as to what type of security seal is best for you then a detailed list of types can be found at specialists such as
