Screw size for Steve Ku V10R 18650 battery tube clip screws.

ShineOnYouCrazyDiamond · Oct 12, 2014

Recently I acquired a Ku V10R Ti 18650 battery tube. The purchase didn't come with a clip but it is threaded for the clip which Steve provided originally (a D10 clip I believe - I could be wrong). The screw holes are much to small for the standard 4-40 machine screw size that lights like the McGizmo and Macs lights use, but they look to be centered just right so that type of clip could be attached.

Would anyone happen to know the screw size so that I can pick up a couple of screws for it?

Have you contacted Steve directly? I'm sure he should be able to help.

Thanks Norm. I'll give that a try. I'm not sure why I didn't think to just email him.

Steve actually replied quite quickly. The screw size is M2x.40mm. What does that mean exactly - I'm not so good with screw sizing.

I believe it means 2mm diameter, x 40mm long. Usually the spec also states thread pitch, but when it does not it means it is common.

I actually did a bit of digging. The M2 spec does define that it is 2mm wide. But, the x .40mm actually defines the thread pitch meaning it is 0.40mm between threads. A bit different than the way the imperial system seems to specify thread pitch in threads per inch. Length of the screw is not specified, but I found the ones Steve used appear to have been 6mm long.

M2 = 2mm Diameter

.40mm = Thread pitch

The over all length of the screw is only around 6mm
