Source for Metric machine screws
 

I need about 3 dozen metric machine screws. I need m6 x 1 x 12mm long flat head machine screws with either a hex socket or a star socket. It would be ideal if they were hardened. Anybody know a good source?

Belmetric worked for me. Seems to have a nice selection of stuff that matches our needs including the right coating. Nice for smaller quantities.

Just checked out the Belmetric website for the first time. I've been looking for a one-stop shop for metric hardware with yellow zinc coating, they have a great selection. They also have metric braided hose from Germany!

Edit: also, I see that they carry a complete selection of Cohline fittings. I scoured the internet to find fittings to put together fuel lines for my MFI pump test rig, not easy to find. Belmetric has everthing I needed (but had to order from europe).

By the looks of it they have everything I am going to need to put together my fuel system for the car, too.

Thanks for sharing belmetric. Aircraft Spruce Canada is a source too.

McMaster-Carr refuses to sell to Canada.

For those of you in Chicago, A-Metric is my go-to place for metric fasteners. This is a small husband-and-wife shop (they're either Swiss or French, can't remember) on the north side (Clybourn just north of Fullerton). This won't be of much use to the OP, but I mention this for the benefit of anyone who may wind up at this thread from a search in the future.

Oddly enough, I have bought some nice hardware on ebay.
For instance, these were a great deal for the engine tin bolts:

I've bought from Belmetric and from EagleDay.

EagleDay has some pre-packages assortments that have a lot of the most common sizes nuts, bolts and washers Porsche used. Pretty handy.

spaenaur in Kitchener for Canada . They have an online catalogue . I get all my metric yellow zinc hardware from there.

If you type "m6 x 1 x 12mm" into the search engine for our catalog, they come up.

Do any vendors offer the correct (style and finish) fastener / washer assortments?

Classic9 offers these...

Any others?

If you've researched the links provided thus far, you will have discovered that 36 threaded fasteners may fall short of the quantities many sources require.

As for "hardened" fasteners, metric and SAE fasteners use a standard marking system describing their tensile strength. You should familiarize yourself with those differences before ordering for your specific needs, especially if used in a strength-critical application.
e.g. https://www.fastenal.com/en/76/metric-system-and-specifications

Another issue to consider is that only a few sources provide the more "correct" yellow anti-corrosion finish (CAD or zinc) on their threaded fasteners. In addition, the anti-corrosion properties of CAD plating are typically better than the more common zinc plated fasteners. YMMV.

Hope this helps,

I like Grainger

Wayne, you used to sell bulk m8 and m6. Pretty sure I bought them in a box of 50s a year or two ago. Searched your site and couldn't find them either... At least in bulk.

My local Ace Hardware has all of that stuff. And I don't have to buy an entire box that might be the wrong size. You might want to try them.
