Help with BSF fasteners - Erich - 08-06-2019
Hi All,
Here in colonies, it is sometimes difficult to come up with imperial fasteners. I am in need of 3/16 X 1/2 BSF round head slotted screws and nuts, in either stainless or plain plated steel. Can anyone steer me to a supplier or alternatively send me some for a price. I need twenty of each.

Hi Erich,
You can find odds and sods on eBay UK, the chances are you will have to buy what's available and cut them down to length e.g.
https://www.ebay.co.uk/itm/3-16-BSF-X-1-1-4-Long-Round-Head-Slotted-Bolts-Machine-Screws-X-20/323828344147?hash=item4b65ac6553:g:oMoAAOSwMilchPTS
I would have suggested Namrick but I don't see any round head screws in their listing - might be worth asking.

I should imagine both sources would ship to the US at cost but I'm afraid the total is likely to be off-putting.
If you find a supplier who won't ship to USA message me, I'm sure we could work something out.

I noted from some old mag that using stainless steel for fastenings starts the same corrosion as experienced with steel/aluminium. Anyone able to comment?

Not sure, but stainless nuts on stainless bolts will pickup before you get the them fully tightened.If I use stainless bolts, I use ordinary steel nuts.Don’t Use stainless as a replacement for safety related bolts it does not have the same strength .

If you use stainless steel fasteners in aluminium, galvanic corrosion will eventually attack the aluminium.
It's not quite the catastrophe it sounds, and is only likely to cause a real problem if you use aluminium fasteners (e.g. pop rivets) to secure a large stainless part i.e. the bulk of stainless is significant in relation to the bulk of ally.

You will find it much easier to get 2 BA screws as they are still used in model engineering.Pitch and dia are almost identical.

10-32 UNF screws are a very close match to 3/16" BSF, and will be easily available on your side of the pond.

I have a stock of these Erich - they are longer than 1/2" but I simply cut them down to suit the application.
