10mm Grade 40 DIN766 or ISO4565 Calibrated Anchor Chain from Lofrans, renowned worldwide for their range of quality windlasses

Lofrans Chain
Lofrans 10mm Grade 40 is clearly stamped LFR on every 10th link as testimony to their belief in the quality of their chain

10mm Lofrans Grade 40 Anchor Chain is generally suitable for yachts up to approximately 16 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.

There are two main calibrations for 10mm chain - DIN766 (10 x 28) and ISO4565 (10 x 30).
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 Lofrans 10mm DIN766 = approximately 298mm
Jimmy Green Lofrans 10mm ISO = approximately 318mm
How to determine the correct calibration

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.
10mm Lofrans DIN766 pitch tolerance is Plus or Minus 1.5mm
10mm Lofrans ISO4565 pitch tolerance is Plus or Minus 1.0mm

Maximum Pin Diameter = 13mm = the largest pin which will fit comfortably in the end link of 10mm DIN766 or ISO chain.

Select the largest possible galvanised shackle or anchor connector by pin diameter to fit the chain.

Jimmy Green 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 Lofrans Test Certificate is available with your order on request.

Lofrans New Galvanising Advisory
Occasionally new chain may have little marks which look like the galvanising is missing.
However, hot dip galvanising is not a coating but a chemical fusion.
The process is explained in detail in this article: HOW GALVANISING WORKS
These flaws are therefore most likely caused by a tiny bit of impurity contamination in the galvanising process.
Lofrans attest that these blemishes will not have a detrimental affect on the effectiveness or longevity of the galvanising on their chain.
The picture below shows a single mark on this Lofrans galvanising:
