High Security Bolt Seal

 

How Do You Use a Bolt Seal

The bolt container seal procedure for application is fairly straightforward. These are the steps to apply one:

 

Record or confirm the correct serial number for the bolt seal. Since each seal has a unique tracking number, it is important that the correct individual seal is used and recorded.

 

Separate the bolt from the cap. Each bolt seal has two parts: the plastic-topped metal bolt portion and the cap. These two parts come connected together by a piece of thin plastic designed to be broken apart by hand before application.

 

Insert the bolt through the door latch. Each container style may have a slightly different latch setup, but there will be two metal components with holes that line up when the door is closed designed to place a bolt through.

 

Apply the cap. Push the cap onto the metal end of the bolt once it is in place. Caps are designed to be able to be applied easily by hand, but not removed.

 

Key Components of Bolt Seal

Bolt/Pin

This is a solid steel shaft, often coated with plastic for environmental protection and color-coding. One end is typically pointed for easy insertion, and the other features grooves or a specific profile that engages with the locking mechanism.

 

Locking Body/Bush

This component houses the locking mechanism. It is usually made of steel and encased in a durable plastic shell, which can be customized with colors, company logos, serial numbers, and barcodes.

 

Technical Focus

When the pin is inserted into the locking body, internal spring-loaded components, often ball bearings or locking collets, snap into place around the pin's grooves. This creates a permanent, non-reversible lock. The plastic coating on both parts also plays a role; if tampered with, it will show signs of stress, discoloration, or breakage.

 

 

How Bolt Seal Work
 

Application: The bolt is inserted through the aligned holes of the container’s locking hasps (the metal fittings on the doors).

 

Locking: The barrel is then pushed firmly onto the end of the bolt until it clicks, indicating a secure lock. This action creates a strong, physical barrier.

 

Unique Identification: Each bolt seal is permanently marked with a unique serial number, often accompanied by a barcode. This number is recorded on shipping documents, allowing for precise tracking and verification throughout the journey.

 

Tamper Evidence: The design is engineered so that any unauthorized attempt to open, bypass, or manipulate the seal will cause visible damage to either the bolt or the barrel, making tampering immediately evident to customs officials, receivers, or any authorized personnel inspecting the container.

 

Removal: The seal can only be removed at the destination by cutting the bolt with powerful bolt cutters. The destroyed seal serves as proof of opening and cannot be reused.

 

Application of Bolt Seal

 

1

Transportation and Logistics

One of the primary applications of bolt seals is in the transportation and logistics industry. These seals are used to secure shipping containers, trailers, and railcars during transit, ensuring the integrity of the cargo and preventing theft and tampering.

2

Shipping Containers

Shipping containers are used to transport goods around the world, and they are often vulnerable to theft and tampering. Bolt seals are an effective way to secure these containers and provide a visible deterrent to potential thieves.

3

Trailers and Railcars

Trailers and railcars are also commonly used in the transportation of goods, and they require reliable security solutions to protect the cargo. Bolt seals are an ideal choice for these applications because they are easy to install and provide a high level of security.

4

Oil and Gas Industry

The oil and gas industry is another sector that relies heavily on bolt seals for security. These seals are used to secure valves, pipelines, and storage tanks to prevent unauthorized access and tampering.

Q: What is the difference between cable seal and bolt seal?

A: A bolt seal is more compact and can be cut off with standard bolt cutters or rotary cutter or portable saw. Cable seals are harder to cut because they require a sharp bypass cutter to remove.
