After most of 3 cooling seasons, our return air grill cover screw holes were about worn out.

I picked up some 8-32 x 3/4" "truss head" machine screws and some 8-32 flat speed nuts along with some 8-32 thumb screws.

I installed the screws from the back side of the ceiling paneling, threaded on and tightened the speed nuts to hold the screw in place, then reinstalled the grill and wing nuts. Makes for an easy change/cleaning of the return filter material.

I want to find some white 8-32 threaded knobs to make the installation look more professional.

Thanks for posting this fix. Next time at Lowes I'll get the screws.

We did the white knobs as posted sometime back on the forum. Only negative was they were glass & one fell on the countertop & chipped the knob. It's so much easier for me to clean filters.

I also found more of the same foam material at WalMart & is cheaper than CW or Lowe's. Its a seasonal item since it was sitting with the AC's. Tried the electrostatic filter material but it's just as easy to clean & rotate with new foam pieces I cut.
