What is the application of the bolt seal?
Mar 06, 2018

Bolt seals are used to secure shipping containers, trucks and trailers. A bolt seal used for securing containers must conform to the ISO 17712 high-security seal in order to be accepted by customs all around the world in ocean shipping.


Bolt seals are generally closed by hand (by pushing the seal body and head together) and opened with the use of bolt cutters.This gives a strong and secure seal for transportation while remaining convenient for staff in ports and warehouses.
