Acme Seals Bolt Seal

The Acme BS2 Seal is an ISO 17712:2013 (E) compliant high security bolt seal, designed for high value ISO container cargo shipments. The bolt head is embossed with the company name and the letter ‘H’ as a compliant seal and the bush is plastic coated for laser marking sequential number/logo. The seals are packed in high quality clear re-closable wallets of ten seals, making it easy to remove seals singularly and then reclose the wallet. When the seal has been locked the bolt spins freely on the locking bush to confirm seal integrity. The seal can only be removed using bolt croppers.
