In Aldi this afternoon and they have packs of Stainless Steel screws - 3 different packs at £3.99 each. Good selection of screws in each pack and good value.

Saw that advertised, they're A2 stainless, marine quality is usually A4 I believe (don't profess to know the difference)

FYI

300 Series—austenitic chromium-nickel alloys

Type 301—highly ductile, for formed products. Also hardens rapidly during mechanical working. Good weldability. Better wear resistance and fatigue strength than 304.
Type 302—same corrosion resistance as 304, with slightly higher strength due to added carbon.
Type 303—free machining version of 304 via addition of sulfur and phosphorus. Also referred to as "A1" in accordance with ISO 3506.
Type 304—the most common grade; the classic 18/8 (18% chromium, 8% nickel) stainless steel. Outside of the US it is commonly known as "A2 stainless steel", in accordance with ISO 3506 (not to be confused with A2 tool steel).
Type 316—the second most common grade (after 304); for food and surgical stainless steel uses; alloy addition of molybdenum prevents specific forms of corrosion. It is also known as marine grade stainless steel due to its increased resistance to chloride corrosion compared to type 304. 316 is often used for building nuclear reprocessing plants.

I find A2 OK for some jobs on board they're useful enough for all sorts of non marine jobs, number plates for example.

What providence do they have?

Likewise, I would not use them in contact with seawater but they are fine for inside the boat or in the garden. I have a boatyard ladder assembled with Screwfix cheapy A2 and they still look bright despite living 20 yards from the briny.

Perhaps you meant provenance and have an officious spellchecker.

Subtle!

To the point!

Probably similar to those that I bought on several occasions from Lidl.
I have used them to replace the bronze(?) woodscrews that hold the sole panels down to the floors (some of which just snapped when I had to remove them to gain access to the flexible water tank that lives in the keel) and also when I built a new passerelle to get onto the boat from the pontoon among other projects. They were extremely sharp and the 'self-tapping' thread was crisp. Some of them were Torx and so there was no danger of the bit slipping and damaging the wood, nor was there any danger of cuts on the end of a slot head.
I have since accumulated quite a selection of sizes and I find that they are very good value for money.

Thanks, I'll try them but if they stick to a magnet I may not use them on my boat

Got the last box at my local yesterday.

They passed the magnet test with flying colours.

I don't know if there are different types on sale, but mine cost £4.99 for 320 PZ chipboard screws which included 8 different sizes/lengths. All countersunk . Really useful box as well.
