MDF or ply?

Hi Eddy C

T Nuts are OK but they tend to work loose and fall out after they have been used a bit unless you put another sheet behind them.

These are better....

You just drill a hole and screw them in with an Allan key (or see video below for another type). Very strong.

Thanks John, I've used similar to those before, I see what you mean about the T Nuts with vibration about. Do you think he's correct when he says it's not a screwdriver slot ?
