Cheap bolts & required quality

A2 refers to the lower grade stainless 304. These are still good in wet but non corrosive environments. A4 on a nut implies 316.

Thanks for your help.
How important is it to maintain the same grade of stainless steel is it in a UK maritime but not coastal climate?
From my googling it would appear that the 038D-10 hangers are 316 whilst the bolts themselves are 304.
Ian T:
I think a good rule of thumb is use the best quality bolts you can afford, rather than the cheapest you can get away with.
Usually works out better in the long term.
Lopez:
You can put a magnet to the bits for a good indication of what they are.
It it sticks like shit it's plain steel (plus probably a coating of something)
If it kind of sticks but it's sort of weak, it's duplex stainless.
If it doesn't stick it'll be 304 or 316
Edit: According to this below 038D could be the old duplex SS ones, or newer 316

Edit again: And according to this below, 038D would be the code just for the duplex/plx hangers. (Full code should be 038D-10OLX). The new ones made of 316 are coded/stamped V00410

galpinos:
038-10D is the Fixe code for the material they branded PLX, which is a Duplex SS.
Depending on the age of the hangers, there was a recall on PLX hangers in 2017:
