Source for metric screws?

**4V50 Gary** · May 27, 2023, 01:24 PM

I need 2 M-4 Metric machine screws.

1) They must be flat head (bigger at top and tapering down to shaft)
2) Slotted (no philips or anythng fancy) head
3) steel
4) preferably black/blue

I've tried Fastenal and they only have philips or what not.

If McMaster doesn't have it, it didn't exist

Interesting !! Have you tried McMaster-Carr, tel:+16308330300. If all you find, is plated, you can remove the plating and reblue, black oxide. I had to do this, on a simulare project.

Be Safe !!!

The only black M4 slotted on McMaster-Carr appear to be plastic.

The screw head that you are looking for is called (oval head).

Smoke & Recoil · May 27, 2023, 06:09 PM

Oop's on my last post, I just edited it to read (oval head).

tangolima · May 27, 2023, 06:49 PM

The exact part you are looking for is rather rare. They don't make many slotted heads nowadays because of weak demand. Rare things are usually expensive. How much are you willing to pay for such screw? A CNC shop can make almost any parts if you don't mind the price.

I needed a metric screw for gew88. I found one in stainless steel with philips head. I hacksawed a slot on the head and painted both ends black. No good to a collector, but quite alright to me. My improvision to keep it going is part of its history now.

No, they have stainless too. But OP wants black or blued.

You might be stuck with getting stainless and then getting them nitrided to black.

M4 slotted screws are like 4-40 cup point set screws.
They exist and are commonly used by manufacturers, but finding them in the wild can be very frustrating.

What do you need them for? Someone might know of an alternative, or original parts.

**4V50 Gary** · May 28, 2023, 07:33 AM

Per a suggestion, I got them off FleaBay. McMaster-Carr has them but $24 postage for a lifetime supply (100) killed it for me. I'm rebuilding a muzzleloading squirrelgun. Just made a horn nose for it (go to blackpowder forum for image)

A squirrel gun with French screws? Ugh.

Jim - lock was made in either Italy or Spain.

Jim Watson · May 28, 2023, 06:40 PM

I figured Spain, subverted by the French System.

Brownell's or Midwest Gun Works?

stinkeypete · May 30, 2023, 07:56 AM

Depending on the stainless, you might be able to nitre blue it...

**4V50 Gary** · May 30, 2023, 08:03 AM

Ordered the screws from FleBay. McMaster Carr has them but postage was $24!
