Product Tips
✔️ Important: Match the ANSI (metric conversion) or NPT Tap and Extension dimension for the square and shank.
✔️ Line up the Tap square corners with the extension inner marks.
✔️ Tap the square of the extension with a brass or lead hammer or or block to seat the tap firmly.
✔️ Tap square should be slightly visible but not covering the slot window.
✔️Only the drift provided can dislodge the Tap from the Extension. Insert the drift into the slot and move in an up and downward motion or tap drift through with a hammer or block.
