Dear All,

I removed a stanchion base bolt last week, and my suspicions of severe corrosion (re rust staining on the deck near the base) were proved correct.

Naturally, these are imperial sized bolts. Any idea re getting replacements, or is it a case of making a slightly larger hole and fitting a bigger bolt?

Many thanks for any advice

Simon

If your stanchions are like ours (1971 boat), the bolt screws into a nut/backing of some sort that has been glassed in below deck; you won't be able to just drop a bigger one in. I would recommend you use the same size unless you want to chisel out and replace those too. Our countersunk machine screws (bolts) have apparently been trimmed prior to the glassing in. It's a pain in the backside if the nut starts rotating.

Stainless steel machine screws are available in imperial threads and are relatively easy to find via google but you need to identify exactly what thread you have.

Thanks for that quick reply. I managed to remove the nut and washer from the underside, so might just go for a slightly larger bolt. Most of the others are as you say, well glassed in, and very awkward to get to, so will not interfere with any of those, unless they start showing rust stains as well.
