Introduction to Bolt Seal
A bolt seal is a type of security seal commonly used in various industries, especially in the transportation and logistics sectors. It is designed to provide a high - level of security and tamper - evidence for containers, trucks, trailers, and other types of cargo storage units. Bolt seals typically consist of a bolt - like body that is inserted through a hasp or a locking mechanism and then locked in place. Once locked, it can only be removed by cutting or breaking the seal, which will leave obvious signs of tampering. This makes it an ideal solution for ensuring the integrity of goods during transit and storage.
