Seco 02436168 Lock Screw TP20 Torx Plus M5 Thread

Product Description

The SECO 02436168 is a lock screw designed to secure indexable inserts on turning toolholders. It features a Torx Plus TP20 drive and an M5 thread, providing consistent clamping force and reliable insert retention during cutting operations. The countersunk head design seats flush with the toolholder pocket, keeping the insert accurately positioned under load. This type of fastener is a routine replacement consumable in any shop running indexable turning tooling, and it is installed by machinists or tool-crib personnel during insert changes or after thread wear.

This lock screw is intended for use in indexable turning applications where M5 thread fasteners are specified. It is anvil-compatible, making it suitable for toolholder designs that incorporate a hardened anvil beneath the insert seat. Typical install scenarios include production turning centers and manual lathes where indexable inserts are changed at regular intervals. The screw is sold individually but must be ordered in a minimum quantity of 10 units.

Installation Notes

Lock screws of this type are installed and replaced by machinists or toolroom technicians during routine insert indexing or toolholder maintenance. Always ensure the machine spindle is stopped and power is locked out before servicing any toolholder. Use a calibrated Torx Plus TP20 key and follow the toolholder manufacturer's recommended seating procedure. Inspect threads on the toolholder pocket before installing a new screw, and replace the screw if thread deformation or galling is observed.
