I have been looking for a source of stainless steel clevis pins to replace on all standing rigging. The problem is that the grip length or effective length seems to be nonstandard on the current rigging. OK, so I can drill a new hole or add washers. The other situation is the regular store/catalogue pins seem to be cheaper quality than the old standing rigging pins. The new stainless steel pins seem "softer" than the original. Anybody have a source on standing rigging clevis pins that are the same or better quality than the original?

Stainless hardens with use it's called work hardening and is one of
the drawbacks of stainless. It can work harden to the point that it
becomes brittle. I can't be sure that is the difference between the
new and the old pins. Are the pins you bought from a well known
marine hardware maker? I would consider it a quality product. and
use it. If t you ordered it on line from an unknown I would consider
it suspect. There are many kinds of stainless and 316 is considered
the best for Marine use. Doug

HI Doug, Thanks for the reply. Sourcing good hardware is getting harder to do. Even large marine retailers are taken by the price point markup from non-confirm-able Chinese sources. I work in the aviation industry where we have been plagued by bogus non-TSO hardware. I figured age/work hardening of the metal would play a part in the difference. But, side by side there is no comparison in quality of finish and hardness of the older pieces. Maybe there is nothing to this thought process and the new clevis/shear pins will be just fine. Just wondered if anybody else noticed or had issues.Cheers......Tim From: "Douglas Pollard dougpol2@...

I feel your pain. Since the sizes were problematic, we changed everything at the same time - new bronze turnbuckles and toggles, new wire, new pins. It was the best solution I could come up with. We bought new American made 316 SS wire rope (The boatyard manager made a point of showing us the new spool he opened for us and pointed out the source while he stripped off the first few feet of the spool and discarded it). That was in Hawaii.Later, after the rig failed halfway to Seattle, Brion Toss examined the wire in Port Townsend and told us that, while it is true that the wire rope was laid up in the USA, the wire strands were produced in China. He said that this is the case with virtually all SS wire rope available at the time (2007). It was the individual strands that began to break on us in mid-Pacific.During that refit in Port Townsend, the machine shop owner that did some small repairs for us told me that the quality of steel used originally in our Vega , as with many of the original components, simply does not exist any more. But then, they don't make anything like they used to it seems.Having said all that, there comes a time when the service life of even the best quality items comes to an end and they must be replaced. In my view, the prudent course is to replace everything from the toggles to the tangs with new, best quality components available that match. Regular inspections and early replacement will keep the rig standing. Good luck!Chuck RoseSV Lealea, V1860
Now most riggers will tell you that the best 1 x 19 rigging wire comes from Korea. The US made wire is not as good.
