PRODUCT OVERVIEW
MC-BS07 overview
Quick answer
MC-BS07 is a single-use bolt seal with a cylindrical (barrel) locking body instead of the more common hexagonal shape. The galvanized low-carbon steel pin is wrapped in ABS, 81.6 mm (3.21 in) long, with a 7.9 mm locking tip, a 6 mm nose and a flat round head. The body is 22 mm in diameter and 31.2 mm high. The catalogue describes it as an 8 mm pin bolt seal. Push the pin through the hasp and into the body until it locks; remove with bolt cutters. MOQ is 1,000 pieces, 10 per box and 250 per carton.
How it locks
The grooved tip snaps into the barrel and cannot be withdrawn without cutting.
Not suitable when
- the hasp hole is smaller than 8 mm;
- bolt cutters and eye protection are not available at the receiving point;
- your shipment requires ISO 17712 documentation – request the current certificate and test report for this exact model before ordering.
Compared with similar models
- MC-BS08 – barrel-style body with a flat steel nail head, MOQ 1,000.

MC-BS07 FAQs
What size is MC-BS07?
The drawing shows an 81.6 mm pin with a 7.9 mm locking tip and a round body 22 mm in diameter and 31.2 mm high.
Why choose a round body?
The cylindrical body has no sharp corners and offers marking space all the way around. Functionally it locks the same way as hexagonal bolt seals.
How is MC-BS07 removed?
With bolt cutters. Wear eye protection, because the steel pin can break sharply. The seal is single-use.
Does MC-BS07 come with ISO 17712 documents?
Ask before ordering. We provide documents only when they identify this exact model; catalogue text and photos alone do not establish a certification.
What is the minimum order?
1,000 pieces, packed 10 per box and 250 per carton.
