Set Screw size and supplier

[Jason L]

I've got a bunch of knobs for my overhead and MIP, but they don't have set screws.  Does anybody know the dimensions of them and a supplier to source some?

Thanks in advance.

If they are OEM knobs, they will be 8-32 thread and 3/16" length - Mil Spec number MS51021-132

Probably other places to get them in the US, but here's one:

I have been getting my fasteners from Accugroup in the UK, they have all the oddball and small sizes for instruments etc, and shipping is super cheap.
I got 300 screws sent on UPS from UK to Australia for only $18 shipping.

Grainger has it all

McMAster-Carr has all kinds.

For a quick local place, find an Ace Hardware Store, they have a pretty decent selection of screws, bolts and fasteners. Not the best prices, but fair and just a card drive away.
