Neptuneseal Bolt Seal

The Neptuneseal is a bolt seal, compliant with high security international standard ISO 17712:2013 and specifically with the requirement of having the internal metal part exceeding 18 mm. The patent pending innovative mechanical design is characterised by two metal tabs attached to the bolt, which securely slot into the locking channel, thus preventing any breaching by high speed spinning of the female part of the seal. Any tampering attempt will give evidence of irreparable damage onto the bolt seal.
