The plan is to start hanging the ductwork for my dust system (just picked the parts up today) in the next few weeks. I can source some nice low cost split circle/bolt together hanger brackets to suit locally. They have an M8 x 15 deep female threaded socket welded to the top side.
I found exactly what i need to mount these these to the T&G floor that is the ceiling above. I think they are called hanger bolts - but there's no name on the examples i found.
They are basically a stud with a Torx socket in one end - the M8 x 18 long male thread is cut on this end (like the Allen key socket in a grub screw), there's a heavy parallel sided woodscrew of about 6mm dia cut on the other end.
The threaded woodscrew section needs to be 15 - 18mm long to suit the thickness of the T&G floor. (don't wants points protruding through it all over the place)
Given that there is an unthreaded section in the middle of the fastener, and that the example i found is listed by Suki as M8 x 50 (the latter number is the total length of the piece) it seems like the ones i need are probably M8 x 35.
My sample is sold by Suki International, but they only seem to come in 4 packs at the daft price of about €2.50 each. The Suki site doesn't go down to that level of detail.
Does anybody have any idea where i might source a more trade type box of 200 - 250 at a reasonable price?
Thanks
PS this type of stud looks like it would be very useful for making up fixtures - run the woodscrew end into a wooden part, and you're left with a nice metric threaded stud standing free for e.g. a clamping knob. You can of course tap the wood to suit M8, but this would be much faster....
