M4 X 10MM T15 TORX FLAT HEAD SCREWS CNC LATHE TOOL KITS
✔️ M4 T15 TORX FLAT HEAD SCREWS 10MM 12.9 GRADE BLACK STEEL KIT

This twenty piece kit secures cutting inserts inside your CNC lathe and milling setups. You will swap them onto turning tool heads to keep carbide blanks locked tight during aggressive machining passes. The flat counter sunk heads sit flush so they never ride above your cut path or trap hot chips.

✅ Exact shank measures M4 diameter thread pulling 10mm total length / 0.39inches
✅ Flat head spans 5.7mm width / 0.22inches sitting perfectly flush below inserts
✅ Engagement depth hits 6mm length / 0.24inches locking cleanly into pre tapped tool holder slots
✅ Star shaped drive calls out a T15 socket wrench for clean installation without marring surrounding aluminum frames

💡 What makes a good replacement screw for holding cutting inserts steady during rough machining runs Stick with solid construction bolts that handle heavy clamping force without yielding to lateral stress. - Pick a handy set of ten grade alloy fasteners that clamp down hard and stay snug against vibration - Match the metric shank size to your machine block holes and cross check with inch equivalents on old bills of material - Swap the star shaped drive bits into your electric driver so the sockets bite tight without rounding off under torque
