Insulation Washer 2 3/4-70mm for 3/16-4.8mm screw

I needed an insulation washer/pin to use with a tapcon style 3/16" screw, i could only find the exact type i needed in 250 or 500 count packs so i just made one myself based on Hilti or Trufast style insulation pins used with masonry nails.

This is used with fiberglass insulation that has a thin film plastic backing, typically used on bare basement walls that are close to grade.

3/16 concrete screws do engage the walls of this pin and i made it for the tapered head style of concrete screws.
