An embarassing question:
I am currently making a custom baseplate for my makita router. The Makita website says their baseplate screws are w3/16 – 24 x 10. I should be able to find these at my local Home Depot, but no one there seems to know exactly what these numbers represent, and therefore cannot help me. Could someone please define these screw dimmensions for me, and if they are not readily available at a home improvement center, tell me where I might get some?

Maybe 3/16 Whitworth (which has 24 threads/inch)? Don't know about the 10 at the end though.
I have a Makita 3612. The base screws are metric. I can't remember the size.
It's a very confusing issue. I believe Don is right about the tpi, and I think the 10 is relating to the length of the screw. To me, this does represent a metric number. But if that is the case, why the standard 3/16 also?
Jake if you happen to remember, let me know as my HD has plenty of metric machine screws. I'll probably take one to HD tomorrw and see if I can match them, but I hate not knowing what those darn numbers mean.
Thanks to both of you for the reply.
The 24 x 10 refers to 24 threads per inch and the 10 is the diameter. It's just a tad bit smaller in diameter than 1/4 inch. I have no idea what the w3/16 means. Metric cap screws are normally prefixed with an M such as M4, M20, etc. which indicate their diameter in millimeters.
Your best bet is to call Makita and ask them or take one of your screws with you to the home center and match it with one they have.

Got the screws today. Thank you for your help Roger.
Still wonder about why those screws were described with a w3/16. Doesn't matter at this point, but I'd just like to understand what I'm looking at.
So what was the correct designation, #10 x 24TPI x 3/16" length?
They were #10 - 24tpi, but they were not 3/16 in length. The screw that came with the router are 3/8 in. long. Never really did figure out what the 3/16 was referring to.
I got that information from Makita.com from thier schematics pdf file, and it shows the same baseplate screws for all of their routers.
scince I needed longer screws for my new baseplate, the length was irrelevant once I figured out the screw size and the tpi, but I don't know where they got the 3/16 on their schematics. Very odd.
HI,
Unless they're making a different product for the US, the screws are M5 from memory (at least, that's what mine are) Cut the screw to fit - approx 10mm/ 3/8" long.
Cheers,
