This material is more resistant and has a higher thermal inertia, so we can tighten the nozzle more without passing the thread, and having a higher thermal inertia the temperature will remain much more stable during printing.
The v6 Heater Block has been upgraded to clamp both the heater cartridge and thermistor firmly in its place. These design improvements improve the thermal response of the Hotend and make thermistor assembly easier.
This product also comes with the following fixings:
1pc with M3x0.5x3 to clamp thermistor and M3x0.5x10 socket dome screw to clamp heater cartridge.
v5 and v6 Heater Blocks are cross compatible, both use an M6 thread. Note that v6 heater blocks are 0.5mm shorter than v5.
