Shackles

[ash]

Hi

I expect that many of us will be looking for new shackles to use with our shiny chain and anchors.

What will you use? and where will you get them?

I was disappointed to note on a recent visit to Gael Force, Hillington that despite their association with FPM Henderson, many of their shackles were unrated.

Probably a Wichard flush pin shackle. A bit pricey but worth it if considering the quality and expected life. I don't use a swivel so I only need one, the bitter end being secured with a line.

Also this type, not as expensive:-

Note that s3i also offer a testing service, should you require a certified shackle

Do you have any worries about using stainless with the galvanised steel?

I don't have a swivel, but would need one shackle with the pin through the anchor, and one with the pin through the chain link.

I thought of stretching the last link into a more round shape before sending for galvanising so that it would take a bigger pin, but worried that I would do more harm than good.

The search for certified, galvanised shackles was easy peasy, Jimmy Green Marine: -

Ah.... too easy! How about certified, galvanised d shackles with flush pin?

For anybody who hasn't been on this site before, some great info.

Looks like the shackle will become the weakest link....

I used S3i for new standing rigging last change. Did a good job at a fair price. I sent the old stuff, and they returned it with the new set.

Mixing stainless and galvanized isn't a big problem except where there is continuous immersion in seawater. Most don't anchor that long!
I use a Kong connector between anchor and chain, and this connects and swivels Seems to have lasted OK, a few scratches along the length dragging over rocks etc, but in good order after so many years use.

Electroplated zinc isn't incompatible with galvanizing. Both are a zinc coating. Zinc to zinc contact isn't an issue. Where electroplated zinc falls down is in the thickness of the zinc. Life expectancy is directly proportional to thickness. Electroplating can be controlled, and can deposit as little as 3 microns, more commonly 8-10. (a micron is a millionth of a meter, 1000 microns = 1mm) And the zinc isn't alloyed to the steel, just deposited there, so there's a defined cleavage point between steel and zinc. In galv, its alloyed there, so the boundary is indistinct with metals migrating both directions into each other.

I've bought quote a few SS items from Painless Stainless. http://www.ebay.co.uk/itm/Pack-x-2-M12- ... XQ1ZhTgfk2
Not rated, certified etc, but I just get a bigger size, and looks OK. Quality of what I've bought was good.
For fasteners I've used Aruncas, another eBay shop. Excellent.
