These special self-tapping steel screws have a cutting profile built into the thread angle so they require less driving torque and reduce the risk of cracking thin plastic. An IP8 Torx Plus head allows you to apply extra force with less slippage or damage to the recess.
Use these M2.5 x 0.95 mm (12 mm length) screws to mount Mosquito™ and Mosquito Magnum™ hotends to plastic adapters.
