Mechanical Security
High security fasteners provide a tamper evident locking mechanism for the steel doors of international ocean freight containers. Every iso 17712 bolt seals installation requires a heavy duty steel pin and a locking cap that can only be removed with industrial bolt cutters. These devices must pass rigorous testing for tensile strength and impact durability to meet global customs standards.
Security Requirement
Logistics providers use these certified locks to comply with international safety initiatives. A genuine iso 17712 bolt seals unit features a unique serial number on both the pin and the barrel to prevent the replacement of parts after a theft. If the numbers do not match upon arrival at the garment factory, the receiver knows the shipment was accessed during transit.
Tamper Detection
Visual inspections of the locking mechanism can reveal if the metal has been stressed or heated to bypass the seal. Because iso 17712 bolt seals are designed for single use, any evidence of scraping or distortion on the plastic coating indicates an attempted breach. Security protocols require the recording of the seal number on all shipping documents to maintain a chain of custody.
Physical Strength
Steel components must resist thousands of kilograms of pull force to prevent accidental opening.
