Crack in Stainless T-Bolt or Not?

I was looking for an opinion on the photo below. I am doing a thorough inspection of my rigging, but am not very experienced. So, I am not sure exactly what I am looking at. This photo was taken with a macro zoom and appears much like the piece does under a magnifying glass. Working it over with a dye penetrant did not make it substantially more visible.

Thanks for the assistance.

Replace it, my 2 cents!

Re: Crack in Stainless T-Bolt or Not?

Magnaflux or die penetrant is how we used to do crack detection.

Anything less than the critical crack length for a specific application should be monitored or replaced.

In this case replace it and probably its mating part. No brainer for a mission critical component.

Wouldn't even have to think twice about replacing it. Looks like a moulding defect or crevice corrosion

Best case it is not a crack but it is still stress riser - Dump it...

And further, that is a great site for developing crevice corrosion...

Replace, and carefully inspect all the other fittings (again!).
