High-Security Bolt Seal
What Is It?
The High-Security Bolt Seal is a premium tamper-evident locking device engineered to safeguard cargo during storage and transit. Constructed from a hardened steel bolt enclosed in a durable ABS plastic body, it is designed to withstand cutting, prying, and unauthorized tampering attempts. Each seal features laser-engraved, sequential unique serial numbers and a customizable company logo, making it virtually impossible to duplicate or replace unnoticed.
As a single-use (one-time) seal, any attempt to remove it leaves visible damage — providing immediate evidence of interference.
Applications
High-security bolt seals are widely used across logistics and supply chain operations, including:
Shipping containers — securing container doors for ocean freight
Trucks and trailers — protecting road transportation of high-value goods
Rail cars and tankers — securing rail and bulk liquid shipments
Warehouses and storage facilities — sealing doors, cabinets, and cages
Cross-border trade — meeting customs and border security requirements
It is the seal of choice for freight forwarders, customs authorities, and enterprises handling electronics, pharmaceuticals, food, and other sensitive cargo.
