Tread on Meg adapter for backplate?

rogeringebo · 9th March 2006, 09:22

Anyone know the tread off the bolts on singletanka-adaptor of the Meg?
Could it be M8?
Cheers Rodge

also there have been two thread recently about some low profile nut for the backplate, which i found one of them but not the other. So anyone (Stefan), who knows all the threads by heart where is the other thread.
This is the one i found

and the otherone, i believe it was someone who bought these nuts from portlandoceanering, but there were some other recommendations as well. And some pics in the thread.

I'm afraid my memory fails me.

So many threads and so many nuts on this board.

If the STA furnished is US in orgin the greatest likelyhood is that they are 5/16 x 18 tpi. For those across the pond, 8mm = .315", 5/16 = .313", and as such it can be very hard to tell apart. Calipers across the major diameter is not reliable, as it is common for threaded fasteners usually run undersize.

8mm x 1.25 lead = 20.32 Threads per inch vs the 18 tpi on 5/16. Count the threads per inch.

Alternatively get a nut of known thread and see if it fits, don't force it!

And if this is the case, get Tobin's delrin thumb wheels. I'm very happy with mines: much better than stainless wing nuts.

Philippe,

Glad to hear the thumbwheels are working well for you.

We make the thumbwheels in 8mm also. Divingniknaks has the 8mm

I've had mine on for over a year, no rust whatsoever. But then I dive fresh water mostly

. They are made from high grade SS, so some WD40 or silicone spray should protect them reasonably well.
