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 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 prolong the protection against corrosion by up to 25%.
Solid Zinc galvanising has a relatively bright appearance before being exposed to the elements.
7mm Grade 40 DIN766 anchor chain is generally suitable for small yachts up to approximately 8 metres, length overall
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 7mm chain - DIN766
Beware - this chain will not fit a 7mm ISO 4565 gypsy
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.
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 7mm DIN766 = approximately 227mm
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
7mm DIN766 pitch tolerance is Plus 0.4mm or Minus 0.2mm per link
7mm MF Grade 40 DIN766 Dimensions:
|Chain Size||Outside Width||Pitch|
7mm MF Grade 40 DIN766 Specification:
|Maximum Pin Ø||Proof Load||MBL||Weight per metre|
1Kn Force = 101.972Kg Break Load
30Kn = approximately 3059kg
MBL = Manufacturer Break Load
Maximum Pin Ø (Diameter) refers to the largest pin which will fit comfortably in the end link of 7mm DIN766 chain
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:
