Bolt seal

Shanghai Xinfan Container Fittings Co., Ltd. manufactures this galvanized bolt seal for securing containers and cargo during international transport. The seal features an 8mm diameter steel perch and is constructed from low carbon steel with an ABS wrapping for added identification and tamper indication. It carries ISO/PAS 17712 certification and C-TPAT compliance, meeting the security standards required for cross-border shipping. The bright colour finish aids visual inspection during customs and port checks.

The low carbon steel body provides adequate tensile strength for container door locking while remaining cost-effective for single-use applications. The ABS plastic coating serves both as a colour identifier and a barrier against corrosion during maritime exposure. Standard bolt seals in this category typically achieve shear resistance above 1,000 kgf and withstand tensile loads of 1,000 to 1,500 kgf before failure. The locking mechanism uses a self-locking pin that snaps into a barrel chamber, creating a permanent closure until cut with bolt cutters. Typical galvanizing follows ASTM A153 or equivalent hot-dip zinc coating standards to prevent rust in salt-air environments.

Logistics operators, freight forwarders, and shipping lines are the primary buyers of this bolt seal, using it on standard ISO containers, trailer doors, and rail freight cars. The seal is applied by hand without tools and removed with heavy-duty cutters, making it practical for high-volume port operations.
