Stainless steel allen screws

[ettingtonliam]

Does anyone know of a source of supply for stainlees allen screws in small quantities, typically 20 or 30 per size? I'd be looking for 2BA and 4BA csk x 1/2" long and 2BA and 4 BA cap screws x 1" long. As an alternative, if its easier, and I haven't tapped the holes they go into yet, 5mm or 4mm in place of the 2BA and 4BA.

Its for fixings into blind bushes on the outside of my boiler, not particularly aggressive environment, but just in case, I'd prefer to use stainless rather than carbon steel.

Thanks for the prompt response chaps.

Whats the difference in the properties of 304 and 316 stainless steel when used in fasteners?

316 has 2% molybdenum added to resist sea water corrosion, among others!

There are loads of Stainless Cap screws on eBay if you choose Metric sizes. I've recently bought M1, M1.4 and M1.6 which are ideal for ME work, as well as the common larger sizes.
