I would think that a decent hardware store, one that has a good assortment of nuts, bolts, screws would have thread checkers and gauges to determine the size you need from what came with the LA adaptor.

Our "big box" hardware stores ( Lowes, etc) have them, as should any good hardware store. Auto parts stores, mechanics, machine shops, etc would be other likely places to have thread checkers etc. I bought checkers for myself off amazon. Don't have the LA adaptor, so can't check for you.

If you do go out locally to find out your self, might want to take the adaptor and screw both along . Either can be checked with the proper tools.

You may still need to order online if what you are after is a bit uncommon.

Confirmed, the LA adapter does NOT use 10-24 screws, these ones do not fit. I'll post some pics later.

As promised here is the pic for comparison. Like I said, I knew as soon as I looked at the thread in the flesh that they weren't going to fit.

The screws on my Low-Angle Adapter are 10-32 UNF; fine thread as opposed to the 10-24 UNC which is coarse thread. That also jives with your photograph.

Number 10 screws are supposed to be 3/16" nominal, which is 0.1875" diameter.

Generally, fine threads are used to get more engagement with the material. Coarse threads are used where pull strength is not that important, or where the material is soft. The shallower depth of fine threads would more easily shear and pull out of a soft material. In the case of the Low-Angle Adapter, the strength of the aluminum alloy is high enough that fine threads are the better answer. At least I'm assuming that whoever is doing Wicked Edge's engineering has come to those conclusions.

My LAA also came with flat-head screws for both upper and lower positions, although there is no countersink at the lower position. A machine set screw would eliminate the head, but you'd need an additional wrench and a very small one at that. The wrench and socket may be too wimpy to produce the required torque. That all would explain why they used a flat-head screw. Same tool, more torque. Better to use the flat-head screw and grind away the unnecessary countersink flange. If the screw still sticks out too far, grind some length off the business end. Buy another 10-32 screw if you need to go back to the longer screw.

If you like, I have some stainless socket-head cap screws in 10-32. Send me a personal mail with your address and I'll send you a couple.

Aha, 10-32 UNF !!

Of course, that makes sense now. Like an idiot I was looking in the UNC section of websites for number 10 screws with a higher thread count and coming up blank, but obviously I should have been looking in UNF sections, much more sensible.

Thank you, I should now have everything I need to purchase the right stuff for myself, much appreciated.

Exciting news! I have the 10-32 UNF screws here at my desk and they look much more likely to fit. Will post another update later as I know you're all on the edges of your seats waiting to find out the answer ;)

I'll see how the grub screws feel for torque, and whether the smaller hex key seems like it's going to snap under the strain.

Good news, the 10-32 UNF screws are indeed the correct ones.

Using a 5/16" length grub screw I was able to get enough torque/clamping force to sharpen my Benchmade Griptilian despite the smaller size hex key that goes inside the grub screws compared to screws with a head on them.

But I bought a selection of headed lengths as well (both countersunk and rounded head)in case I want to try them. I suspect they'll be handy for 'taller' blades like kitcken knives, where there's more length between the edge and the spine.
