Hello Mike, these T-nuts look great.

Do you flatten the prongs or leave them as is? It's hard to tell, but some of them look like they might be long enough to go right through my 4mm ply and poke out the top a bit.

thanks

Peter

: Typical installation: Drill a hole the size of the threaded barrel part, mix
: up some epoxy, paint the hole, then from the underside (the hidden side),
: push the threaded barrel part up through the hole, then either tap in
: place, or like I like doing, thread a bolt of the right thread into the
: barrel from the top and pull it up by tightening against the appropriate
: sized fender washer. This will draw the flange tight against the
: undersurface-let's say a deck-leaving a nicely threaded hole. It's a
: convent way to install mounting points and leave a professional,
: workmanlike appearance.
