Need Good Source for Screws


My client is asking for a good, relaible source for self-threading #4, 1 inch long screws. They usually use for fasteners but apparently McMaster doesn’t stock this particular size so we have to look and buy elsewhere. Any tips?

You might try Fastenal

Looks like even Fastenal carries only up to 1/2" Fastenal Industrial Supplies, OEM Fasteners, Safety Products & More | Fastenal

Might be something they could special order.

Or maybe Wurth has something?

Try calling up McMaster and asking them if they can get them. Even if they do not stock the item normally, I have found that they sometimes have resources for getting items that are very similar to what they do sell.

Give them a call and check.
