Manufactured from steel, this M2.5 x 0.45 threaded fastener has an overall length of approximately 0.2 inches (5.08 mm) and is driven with an F Key. It belongs to the QTM series and is intended for use with QTM20 industry standard toolholders. Licensed machinists and toolroom technicians install this component as part of routine insert changes on indexable boring setups, where consistent clamping force directly affects insert seating, surface finish, and tool life.\u003c\/p\u003e\n\u003cp\u003eThis insert screw is used in small hole boring applications on CNC turning centers, boring mills, and manual lathes equipped with compatible QTM series boring bar toolholders. Typical install scenarios include production insert indexing and replacement during scheduled tooling maintenance. The part ships in a quantity of one and is ordered as a single-unit replacement, making it practical for restocking individual fasteners lost or damaged during insert changes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eT7 Torx drive for positive engagement and reduced cam-out during insert clamping\u003c\/li\u003e\n  \u003cli\u003eM2.5 x 0.45 thread size matched to QTM series boring bar insert pockets\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated torquing cycles\u003c\/li\u003e\n  \u003cli\u003eCompatible with F Key driver for access in tight small-bore toolholder geometries\u003c\/li\u003e\n  \u003cli\u003eConforms to QTM20 industry standard for straightforward sourcing and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with QTM series small hole boring bar toolholders using the QTM20 industry standard, with hardware compatibility for boring applications.
