Screw- Self tapper Stainless Steel, screws into 4mm hole

Choose the thread length from the sales drop down list.

These screws will correctly screw into our USA made housings and others with a 4mm hole in the plastic. The shorter (67100S) with 12mm of thread will suit when using stainless steel mounting brackets and the longer (67100) having 18mm of thread will suit when using the thicker plastic bases for benchtop filters and or for screwing undersink brackets to side wall panels.
