This is A2 rather than A4. In case you don't know A4 is recommended for exposed marine applications as it has greater resistance to salt water etc. due to the addition of molybdenum. However A2 is actually stronger. On my ocean-going yacht I'd use A4 outside, but for light coastal or any inland application I would personally consider A2 fine. If unsure do more research."
"Good all round stainless steel product. Comes with stainless steel screws as well. I've installed these on my house near the guttering so that I have something to tie my ladder too for extra safety. With it being stainless steel, I dont really have to worry about it rusting."
"I bought these eye plates to secure a very large plant in a pot, always blows over in a strong wind & damages the plant. These fixed easily and securely to nearby wood frame and with a turnbuckle I was able to hold the pot tight using washing line rope. So far they have shown good weather resistance."
"Attractive, highly polished eye plates. I fitted these in an exposed semi coastal location several months ago and there is no sign of corrosion to date; the japanned ones used before were rusty within a couple of weeks. The stainless screws supplied are a bonus, but the heads seemed quite soft, so care is needed when fitting."
"Not sure what the previous reviewers are talking about, but the description is 304 grade which is A2. If they want A4 then they need to look for 316. That said, 304 is good for general corrosion resistance, but don't expect it not to tarnish outside (especially near the coast). For true "marine" grade, find 316 or A4 stainless steel."
