Grade 12.9 Torx Socket Screws for CNC Carbide Inserts | M2–M6 | 10pc or 50pc

Grade 12.9 Torx Socket Screws for CNC Carbide Insert Tool Holders — M2 to M6

These are the screws that hold your carbide inserts in place — and they need to be right. Made from Grade 12.9 high-tensile carbon steel, these Torx (six-lobe / T-drive) socket head machine screws are purpose-built for CNC lathe tool holders, turning tools, milling holders, and other carbide insert clamping systems. The Torx drive resists cam-out under high torque, making insert changes faster and more reliable. Available in M2 through M6 across a range of lengths, in 10-piece or 50-piece packs.

Key Features

• Grade 12.9 High-Tensile Carbon Steel — Maximum clamping strength for secure insert retention under cutting loads
