I have seen them in a tools-shop few weeks ago. I suppose they are the ones used to fit a wear-out hole in the skis.
I suppose that if the wood-core is hard enough and if they are well placed (putting some epoxy) they should work. I was thinking to give a try.
the good part is you can put them in after the ski is finished. but you would have to make shure you don't screw the M6/5 bolts too far, or it will delaminate the base.
Yes that's the thing i'm thinking off - i would like to put the into the finished ski to make a variable mounting position possible. The ones with M4 thread that are only 8mm long seem to be the right thing!?
M6? - as far as i remember the binding is mounted with 8 x 4,5mm wood screws!? Maybe we're talking about different bindings i ment regular downhill bindings not telemark...
M6 (1/4-20 for english) is pretty much the standard for snowboard bindings. i think K2 uses M5 in their tele skis and Line either uses M5 or M6 for their reactors. i wouldn't recommend going below an M5.
