Product Description
The SECO 02570513 is a cap screw designed for use with indexable cutting tools in turning applications. It features a Torx Plus TP15 drive, which provides a more secure interface between the fastener and the drive tool compared to standard Torx, reducing the risk of cam-out during tightening. The screw is part of Series D and is intended for clamp-style indexable toolholders. Machinists and toolroom technicians use this hardware to secure indexable inserts and clamping components in precision turning setups. At 0.01 pounds, it is a lightweight but critical fastener for maintaining proper insert seating and clamp force.
This cap screw is used in turning toolholder assemblies that rely on a clamp-style insert retention system. It is a direct replacement fastener for worn or damaged screws in Series D indexable turning toolholders. Applications include CNC lathe work and manual turning operations where reliable clamping of carbide or ceramic indexable inserts is required. Toolroom technicians and machinists performing insert changes or toolholder maintenance will encounter this fastener as a standard service item.
Key Features
- Torx Plus TP15 drive for reduced cam-out and consistent clamp torque
- Cap screw design compatible with clamp-style indexable toolholders
- Series D designation for straightforward replacement matching
- Rated for indexable turning tool applications
- Lightweight at 0.01 pounds minimal handling burden during insert change-outs
Compatibility
Designed as a replacement cap screw for Series D clamp-style indexable turning toolholders requiring a TP15 Torx Plus drive fastener.
Installation Notes
Installation is performed by machinists or toolroom technicians during insert changes or toolholder maintenance. Before replacing the screw, ensure the machine spindle is fully stopped and all energy sources are locked out per standard lockout/tagout procedures. Use a proper TP15 Torx Plus driver or key to avoid stripping the drive recess. Do not substitute a standard Torx T15 driver, as the Torx Plus profile differs and may damage the fastener head.
