M16 X 2.0MM MC HSS PLUG TAP LINEAR TOOLS
Stock Code: 21-500-163
Precision hand taps for cutting clean, accurate internal threads in steel, stainless, cast iron and aluminium. Available in metric coarse sizes M3–M20, in three formats:
- Taper: long lead for easy, square starts and through holes.
- Second: medium lead, a good general-purpose choice.
- Plug: short lead for full threads in blind holes.
Tips: drill the correct tapping size first, keep the tap square in a good tap wrench, use cutting fluid, and back off a quarter turn every half turn to break the chip.
