What type of bronze M6 insert should I use if I'm plan to modify a mast foot, recast it, to fit a socket-type joint? I'm talking the type of joint that North, Axis, Code and Lift use.

These brass barrel nuts are used in all Tuttle windsurf fins. Windsurf shops can hook you up.

M8 barrel nuts are impossible to find - but that's what you want. The m6 are easy enough to find but when I convert a mast to North I have to fabricate my own with drill press, vice, drill bit, tap, and stainless rod. For m8 I use a 10mm stainless rod which works well. I burn through taps pretty quick. I've done half a dozen masts like this and it strong enough that the plate end comes apart(never had the plane end fail)

Thanks guys. I forgot to come back to this thread. I need M6. A lot of manufacturers are not using barrels that go perpendicular to bolts... they are using vertical inserts that go in line with the bolts themselves. I like this idea because there it more thread, BUT, they also have to be anchored in VERY well... and I'm don't know exactly how.
I think the idea of using barrels might be the best way to go about this. Is any manufacturer making mast with M6 barrels? I know my Axis masts use M8 barrels, and yes, those are near impossible to find to buy extras.

Slingshot sells m6 barrel nuts in 316 stainless. As spares for phantasm masts.
Brass equivalent should be available at you local chandelry

M6 grows on trees
Just change them on occasion as corrosion swelling makes them split your carbon laminate eventually - and that timing varies... seen it in 2 seasons, or 20yrs
