US screwed thread size question??? - GoFuckYourself.com

TheDA · 04-20-2011, 04:54 AM

If I am buying a Manfrotto tripod head and it has a 3/8" thread, what is the full name for the thread size generally? 3/8 what? Is it Whitworth, UNC, etc? What syste do you use in the US?

If you are going out to buy 3/8 nuts and bolts from Home Depot, what are they generally?

Or is it not quite as simple as that?

3/8" = Three eights of an inch (basically slightly smaller than half an inch which would be 4/8" or 1/2")

Yes I get that bit, I guess I am talking about thread pitch.

I am trying to source fixings in the UK to fit the thread, we have a selection of 3/8" sizes, just trying to understand the system you use over ther to find the closest match here.

The off-the-shelf options I tried earlier do not fit.

what are you going to use the tripod head for? most of the time the heads and legs are of the same thread so they will fit together....

it's either 3/8 x 16 or 3/8 x 24

16 is coarse 24 would be finer

16 threads per inch or 24 threads per inch

I need to make up a separate bracket for a little project I have on the go.

It's the coarse one by the looks of it, just wondered if you had a name for it.

USS Coarse

if it's the fine one it's called SAE Fine

so if you want a nut you would ask for it two ways: a 3/8 x 16 nut or a 3/8 nut in USS Coarse thread.

Ask for bolts the same way except include the length.

Thanks. Not ones I have heard of. I wondered if you had adopted one of the old British imperial systems.

For screws and bolts in North America it's UNC
