What is Bolt Seals

These seals are made of metal and consist of a bolt and a locking mechanism that are fitted together to prevent unwanted access. Bolt seals are designed to be tamper-evident, meaning any attempt to break the seal will leave obvious signs of tampering. These seals are difficult to remove without specialized tools, making them ideal for securing high-value shipments and preventing theft or unauthorized access.

Components of Bolt Seals
 

 

Bolt Body

It is a heavy-duty metal bolt that forms the main structural component of the bolt seal. It locks into the locking housing, making it virtually impossible to open without breaking the seal.

Locking Mechanism

Bolt seals feature a tamper-evident locking mechanism that prevents unauthorized access. The locking mechanism is designed to prevent tampering by interlocking with the bolt body and housing, making it difficult to remove the bolt seal.

Housing

The locking mechanism is encased in a sturdy metal or plastic housing, which is then attached to the bolt body. The housing protects the locking mechanism from tampering and removes the possibility of overriding the bolt seal by sawing through the bolt.

Serial Numbering

Bolt seals feature a unique serial number that helps to identify the product, shipment, or container. This number is usually printed on the bolt seal and recorded in a database.

Barcode or QR Code

Some bolt seals also feature a barcode or QR code that can be scanned to retrieve the serial number information. This technology makes it easier to track and manage large numbers of shipments and containers.

Customization

Bolt seals can be customized with different colors, logos, and other information. This customization helps to easily identify the bolt seal and provides an additional level of security against tampering.

Check the wear and tear

Inspect bolt seals for signs of wear, such as cracks, breaks, or loose parts. If you notice any of these problems, replace the seal.

 
Storage

Store bolt seals in a cool, dry place away from moisture and direct sunlight. Avoid storing seals near chemicals, sharp objects, or other high-risk areas.

 
Check The Tightness

Inspect the seal before use to make sure it is intact and functioning properly. Install the bolt seal securely and tighten it to the recommended torque setting to prevent tampering.

 
Record Details

Record the serial number and other identifying details of the bolt seal for tracking and tracing purposes. This information will be extremely valuable in the event of theft or loss.
