The proof load testing process ensures that each individual weld has been completed successfully.

MF Calibrated Anchor Chain features enhanced Solid Zinc Galvanising treatment with greater micron depth and prolonged protection against corrosion.

MF Solid Zinc Galvanising

MF have developed an enhanced Solid Zinc Galvanising treatment in conjunction with the standard hot dip galvanising process.
Solid Zinc Galvanising is an MF duplex treatment where both aspects of the process are complementary hot dip molten zinc galvanisation.
The improved coverage, micron depth and adhesion properties extended the effective working life of the galvanising by up to 25%.
Solid Zinc galvanising has a bright smooth appearance.


8mm Grade 40 DIN766 anchor chain is generally suitable for small yachts up to approximately 12 metres, length overall

Factor in:
Displacement : Length ratio
Your cruising intentions
The anticipated anchorage conditions e.g. depth, seabed holding characteristics, the length of fetch and degree of exposure to prevailing winds
The length of chain that will be deployed and any extra scope provided by an anchor warp
The weight and design of anchor

Your anchor rode is only as strong as the weakest link so ensure that all your connectors and shackles are rated to the requisite break load

Check your calibration:

There is one main calibration for 8mm chain - DIN766
N.B. Windlass manufacturers sometimes refer to 8mm ISO4565 - this is exactly the same calibration.

It is very important to check the size and calibration of your gypsy/chain before you order
If you are unsure we can help you to decide - we will take all reasonable steps to ensure you get the correct chain

The simplest way to check that you are buying the correct calibration is to take a measurement from your existing chain, providing of course that it fits correctly.

How to determine the correct calibration

We measure 10 links because, in practice, it is difficult to measure one link accurately enough.
The links should be laid out flat and pulled tight.
Measure from the outside edge to outside edge.
Compare your measurement with our stock:
Jimmy Green MF Grade 40 8mm DIN766 = approximately 250mm

N.B. The measurement for an old chain may be a little longer than new due to a degree of wear and elongation in use
8mm DIN766 pitch tolerance is Plus or Minus 0.6mm per link

Quality Control and Accountability
Every length of chain is checked and labelled with the manufacturer, the date received and a corresponding batch number when it arrives.
The batch number is then recorded at the point of sale.
Every chain order is therefore traceable and accountable to the Manufacturer Test Certificate.
A copy of the corresponding MF Catenificio Test Certificate is available with your order on request.

MF chain manufacturing has Lloyds Register approval to the ultimate ISO 9001 quality standard:

MF LLOYDS REGISTER APPROVAL TO ISO 9001
