These high strength security bolt seals are suitable for various types of shipping containers and ground transportation of cargo. All bolt seals are clearly marked for ease of identification.

Silverback bolt seals comply with the requirements for high security seals in accordance with ISO/PAS 17712. The high strength steel pin and anti spin mechanism prevents friction attack. The pin and bush are both molded with ABS to provide highly tamper - evident properties and space for laser marking. The bridge keeps pin & bush together for better storage and easy handling. Protruding fingers provide evidence of tampering if the seal is cut at the joint. Identical sequential numbers on both parts provide greater security as it prevents parts substitution or replacement of seal. You will need large bolt cutters to remove these seals.
