Description
Product Overview
Amarine Made delivers a robust bolt seal built to meet the stringent requirements of C‑TPAT and ISO 17712:2013. Manufactured by Alfa Marine (Shanghai) Co., Ltd, each seal is crafted from high‑grade steel with an 8 mm thick shaft that resists cutting and deformation. The package includes 50 bright yellow bolts, each stamped with a unique progressive serial number, providing a clear audit trail for every container or trailer secured. Weighing 7.45 pounds and measuring 12.91 x 4.84 x 3.7 inches, the seals are compact enough for easy handling yet substantial enough to deter unauthorized entry. The anti‑spin feature adds an extra layer of security by preventing the bolt from rotating once applied, ensuring the seal remains intact throughout transit.
