Bolt Seals–ISO 17712 High Security Anti-Spin Seals for Containers | SNSEAL

ABS & Carbon Steel Construction: Combining a durable ABS outer body with a carbon steel internal structure, this bolt seal provides a robust mechanical locking solution with clear identification for containers and transport equipment.

Anti-Spin Design for Enhanced Tamper Evidence: The anti-spin structure helps reduce unauthorized rotation of the locked bolt, making abnormal manipulation easier to detect and improving tamper-evident protection during cargo transportation.

Unique Numbering for Seal Tracking: Each seal can be marked with a unique serial number, allowing users to record and verify the seal number and physical condition before, during, and after use for better shipment traceability.

Single-Use Design for Clear Tamper Evidence: Designed for one-time use, the locked seal requires bolt cutters for removal and cannot be normally restored for reuse, helping users identify unauthorized opening or interference through the condition of the seal.

Custom Printing & Identification: Support customization through silk-screen printing, hot stamping, or laser printing, including logos, serial numbers, barcodes, and other identification details for branding, cargo identification, and supply chain tracking. Laser numbering and barcode identification are also widely used on high-security bolt seals.

Multiple Color Options for Easy Classification: Available in standard red, yellow, green, and white, with custom colors also available for different brands, cargo categories, or transportation requirements.
