High Security Bolt Seals
These are intended for high-security applications, such as shipping containers, trailers, and rail cars. They are usually made of steel or other high-strength materials and are designed to prevent tampering and unauthorized access.
Cable Seal Bolt
The cable seal bolt consists of a metal bolt and cable that are designed to prevent the bolt from being removed from the lock body. The cable is inserted through the lock body and looped around the item to be secured, then the bolt is inserted and the lock body is closed. The cable is secured in place and cannot be removed without breaking the seal bolt.
Plastic Bolt Seal
This is a cost-effective solution designed to secure cargo trailer doors, containers, and various other shipping equipment. They can be personalized in order to improve your brand image.
Barrier Seal Bolt
Barrier seal bolts are typically made of high-strength materials like hardened steel or titanium, and are designed to resist cutting, drilling, or other physical tampering. They are often used to secure doors, windows, gates, and other access points, and can be used to seal off entire areas if necessary.
GPS Bolt Seal
This new type of bolt seal includes a GPS system that records the exact location and time when the seal was applied, which helps to ensure that your cargo is secure throughout the shipping process.
Barcoded Bolt Seals
Barcoded bolt seals are commonly used in industries such as logistics, transportation, and manufacturing to maintain the integrity of shipments and prevent theft or tampering. They are also useful for tracking and monitoring shipments as they move through the supply chain.

Steel
This is the most common material used in bolt seals. Steel bolt seals are strong, durable, and tamper-resistant.

Plastic
Bolt seals made of plastic are lightweight, easy to use, and cost-effective. However, they are not as strong as steel or aluminum and are therefore not suitable for high-security applications.

Aluminum
Bolt seals made of aluminum are lightweight and rust-resistant. They are commonly used in applications where weight is a concern.

Brass
Brass bolt seals are popular due to their corrosion and weather-resistant properties. They are primarily used in maritime applications.

Zinc
Bolt seals made of zinc are strong and durable. They are commonly used in the transport of goods by sea.

Stainless Steel
Stainless steel bolt seals are highly durable and resistant to corrosion, making them ideal for outdoor and marine use.
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.
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.
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.
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.
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.
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.
Choose the appropriate bolt seal
There are different types of bolt seals available in the market, so you need to choose the one that fits your needs. Bolt seals can vary in size, strength, and features, so select the one that suits you the most.
Insert the bolt seal
Insert the bolt seal into the container or the area that needs to be secured. The bolt seal should be placed in a position that makes it difficult for anyone to tamper with it.
Secure the bolt seal
Secure the bolt seal by pressing down on the locking mechanism. Most bolt seals require a bolt cutter to remove them, so make sure that the bolt seal is well-secured.
Record the seal number
Record the seal number or code for future reference. This helps to track the seal and ensure that it has not been tampered with.
Monitor the seal
Monitor the seal to ensure that it remains secure and has not been tampered with. This includes regular inspections of the area where the bolt seal is placed.
Remove the bolt seal
When it is time to remove the bolt seal, use a bAolt cutter to cut it off. Save the seal number or code for future reference.
Clean the surface of the bolt seal regularly using a soft cloth or brush and a mild soap and water solution. Avoid using abrasive cleaners or sharp tools that may damage the seal.
Apply lubricant to the seal's moving parts to prevent rust and corrosion. Silicone or Teflon lubricants work well and won't attract dirt or dust.
Inspect bolt seals for signs of wear, such as cracks, breaks, or loose parts. If you notice any of these problems, replace the seal.
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.
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 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.
