SS304 Coated ABS Plastic Container Bolt Seal T Type

1. Higher Security Strength

• An 8 mm steel pin is thicker, giving it higher tensile strength.

• It is much harder to cut with bolt cutters compared to a 7 mm pin.

• Provides better resistance to tampering attempts.

• Many shipping lines and customs authorities prefer or mandate ISO 17712:2013 “High Security” certified seals.

• Manufacturers often achieve this certification more reliably with 8 mm pins, because the standard requires specific break strength levels.

• Export containers, long-distance cargo, and high-value shipments benefit from stronger seals.

• An 8 mm bolt seal offers better durability during rough handling, stacking, and long logistics cycles.

• Thicker pins reduce the chance of:

  • Twisting open

  • Bending

  • Partial cutting and resealing attempts

• This ensures your container stays genuinely tamper-evident.

• Many logistics companies prefer 8 mm because it aligns with:

  • Port security norms

  • Cargo insurance requirements

  • International shipping practices

It gives buyers and authorities more confidence in the security level.
