Ordering Info
Bolt security seals are very durable and intended for high security applications, such as:

  • Shipping containers
  • Trucks and trailers
  • Railcars
  • Other heavy-duty sealing applications

We offer bolt seals which qualify as "High Security" seals, comply with ISO 17712:2010, and are C-TPAT compliant.

Both the bolt and barrel have matching serial numbers, which are laser etched into the plastic covering.

Bolt Seal Before Use (MS-B3R)

Bolt Seal After Use (MS-B3R)

The bolt is inserted into the barrel locking mechanism, where the metal bolt snaps into place within the metal locking cylinder.

The metal bolt and metal locking cylinder are encased in plastic, which is designed to show signs of tampering. If attacked with a heat source, the plastic will discolor and/or melt.

Choosing a Bolt Seal

The new ISO 17712:2010 standard for bolt seals is effective on March 1, 2012. The new guideline requires bolts with a minimum diameter of 8mm and other enhanced construction details, which improve security.

Our Premium MS-B5 series bolt seals (8 mm diameter) meets the ISO 17712:2010 standard for High Security. Because the new bolt seal standard offers improved security performance, we recommend this product for shipments which cross international borders.

Our Standard bolt seals (7 mm diameter) only comply with the prior ISO standard (ISO 17712:2006) for High Security. Some customers are still using this product for domestic shipments or applications where security needs are lower.

All of our bolt seals are produced in C-TPAT facilities.

All seals have unique serial numbers; record the serial number for added security.

Bolt seals are offered in multiple colors, which allows for color coding.

All of our bolt seals include an 'anti-spin' feature, which provides added security to prevent un-authorized entry.

All of our bolt seals have a longer operational length which provides added clearance (and convenience) for bolt cutter access to cut the bolt for removal.

Customized bolt seals provide added security. The stock bolt seals (red, blue, yellow) can be customized by imprinting the bolt only. Or we have yellow bolt seals which can be customized on the bolt and barrel.

For added security, if the container/trailer has two hinged doors (each with a keeper bar and hasp), secure both doors with a bolt seal on each door.

For added security on trailer doors, other options include:

- Navaloop BC-03 (shown on this page): a combination bolt seal and cable seal which can secure both doors. The cable provides added security by wrapping it around the keeper bars on the doors. . Then install the connecting bolt in one of the door latches or hasps.

- Cable Seals: available in larger diameters and longer lengths to wrap around the keeper bars on the doors. Sometimes used in addition to or as a substitute for a bolt seal.

- Cargo Door Labels: tamper evident labels which are affixed to the doors to span the door seams. Usually used in addition to a bolt seal.

- Barrier Seals: Heavy duty metal brackets which latch the two doors together. Usually used as a substitute for a bolt seal.

Installation Instructions

  1. Insert the bolt in the latch hole.

  2. Before locking...

    a. Rotate the locking mechanism and bolt until the matching serial numbers are visible and aligned on the same side.

    b. Align the square end of the bolt to fit into the square hole in the lock. Loosely insert the bolt into the lock to assure proper alignment. Any misalignment will make it more difficult to lock.

  3. Push the bolt into the locking barrel until the locking mechanism snaps.

  4. Pull on the bolt & barrel to confirm the locking mechanism is fully engaged.

  5. A bolt cutter is required to remove the bolt seal. Wear safety glasses when removing.

Accommodating Larger Latch Holes

The maximum latch hole size is shown in the specifications. For larger hole openings, add heavy duty metallic washers (with minimum .4 inch diameter hole) on one or both ends of the bolt seal. The outside diameter of the washer should be at least .25 inch larger than the latch opening.

Bolt Seal

Before engaging the locking mechanism, confirm there will be ample room to remove the bolt with a bolt cutter.

Bolt Security Seals

 

Stock Premium Bolt Seals (8 mm diameter bolt)

Our MS-B5 series bolt seals are C-TPAT compliant and meet the new design and construction standards of ISO 17712:2010, which provides improved security. The new standard is effective March 1, 2012.

However, the new ISO standard is not completely finalized and we expect more changes over the next year particularly for tamper evident testing. As the new ISO standard evolves, we will complete testing to assure the MS-B5 bolt seals are compliant with any ISO updates. See "Update on ISO 17712:2010"(below) for more info.

Update on ISO 17712:2010

The current deadline for implemention of ISO17712:2010 is March 1, 2012.

The new standard is intended to improve the security of bolt seals. Suppliers must provide documentation that their seals meet the enhanced construction specifications and received a 'PASS' on the tamper evident performance testing.

The construction specifications are finalized. We can certify that our MS-B5 series bolt seals meet the new current standards for ISO 17712:2010.

The major changes in the new construction specifications include:

  • A minimum 8mm diameter of the steel bolt
  • A minimum 18mm width of the bolt head and locking mechanism
  • An anti-spin feature

However, the new ISO standard also includes tamper evident testing, but the details on these test methods are not finalized. Therefore, at this time, we can only certify the MS-B5 bolt seals meet the portion of ISO 17712:2010 which is final. When the tamper evident testing requirements in the standard are finalized, we will complete any addtional testing to certify that the bolt seals meet the tamper evident testing too.

While the new standard is voluntary, failure to comply could result in shipment delays based on C-TPAT procedures.

Although the tamper evident testing aspects of ISO 17712:2010 are not finalized, the construction specifications and structural performance of the new standard are tangible security improvements to the bolt seal design. Therefore, customers who want improved security should consider the new product standards, especially for cross border shipments.
