High Safety Container Numbered Door Bolt Seal

Bolt seals are usually manufactured using a combination of materials to ensure strength, durability, and security. The common materials used in the manufacturing of bolt seals are hardened steel, metal alloys, plastic, rubber or polyurethane and high-strength polymers.

Bolt seals comprise two main components: a high-strength steel bolt and a hardened steel locking mechanism incorporating tamper-evident features. The bolt is inserted through the locking mechanism, and the items for sealing and tightened to secure them. The locking mechanism includes a locking chamber enclosing and securing the bolt. The locking chamber often contains unique markings or numbers that serve as identification that are recorded for documentation purposes. A Secure Bolt Seal has tamper-evident features to show clear signs of tampering if someone tries to remove or manipulate them. Security features may include anti-spin construction, tamper-evident markings, high-strength materials, and one-time use. Authorized persons need to use appropriate tools to remove the bolt seal to avoid damage to the container or cargo. Removal typically involves cutting or breaking the seal, which results in visible damage.
