Got a bolt stamped THE S30400 I need to replace. I understand THE is the manufacturer (Chinese) and S30400 is the stainless spec.
Apparently S30400 is not a popular grade and need to make sure what I replace it with is at least as good or better since it's going on a jackplate and it's the only thing keeping that 250 hp head chopper from paying me a visit.
Anybody with experience got a recommendation or understanding of stainless grades?

That’s 304 stainless

316ss would be better choice for corrosion resistance especially if it gets into salt water

No salt water but 316 is what I came up with from the "internets" too. Seems the 30400 spec is something them Chinese manufactures came up with to slip stuff in the us market.
Thanks for the help.

Try Fastenal they’ll probably have what you need

Research "Monel". If its good enough for the Navy its good enough for me. You will need very deep pockets tho.
He’s got them deep pockets covered!

Only Problem with fastinal is They will want to sell you 1000 of them in a bulk bag. I'd find a good mom and pop hardware store . They'll likely have stainless hardware in singles. If your worried about tensil strength and want to match it up exactly, why not go back OEM ?
Bill is correct, "Monel" is what we use in the drilling business - "Monel" is non-magnetic Required for telemetry operations. SS 316 will work.Quote:

Y'all watch out for that fella up there. He withholds critical information right when ya need it. Prolly the type to tell you exactly where to catch em right after the weigh in. Pffft.
