Frequently Asked Questions
What is a bolt seal?
A bolt seal is a high-security mechanical seal consisting of a steel bolt and a barrel-shaped lock body. Once the bolt is inserted into the barrel, it locks permanently and can only be removed with bolt cutters. Bolt seals are ISO 17712 certified for international shipping.
Are bolt seals ISO 17712 certified?
Yes, our bolt seals are certified to ISO 17712:2013 High Security Seal standard, meeting C-TPAT and ISPS requirements for international container shipping.
What is the difference between bolt seals and cable seals?
Bolt seals have a rigid steel pin (18mm diameter) with breaking load >=1,000kg, designed for containers. Cable seals use a flexible steel cable and are typically used for valves, meters, and smaller applications. Bolt seals offer higher physical security.
How do you remove a bolt seal?
Bolt seals must be removed with bolt cutters or a specialized bolt seal cutter. The steel bolt cannot be pulled out by hand, ensuring tamper evidence.
