Kennametal 1021535 Lock Pin M5x0.8 2mm Hex Socket

Product Description

The KENNAMETAL 1021535 is a lock pin designed to secure insert clamps on indexable turning tools. It features an M5x0.8 thread and a 2mm hex socket drive, allowing precise tightening with a standard hex key. This small but critical fastener maintains clamp position and insert seating during turning operations, helping preserve dimensional accuracy and tool life. It is used by machinists and CNC lathe operators in production and job-shop environments. Weighing approximately 0.003 pounds, this is a consumable replacement component intended for periodic service of indexable toolholders.

This lock pin is suited for use in metal-cutting applications where indexable turning toolholders are used on CNC lathes and manual turning centers. It is compatible with CKM34 clamps and is a direct replacement component in toolholder assemblies requiring periodic fastener refresh. Shops running high-cycle turning operations will typically keep replacement lock pins on hand to minimize downtime during insert changes or clamp service.

Compatibility

Designed for use with CKM34 clamps on indexable turning toolholders. Consult toolholder documentation to confirm clamp type before ordering replacement lock pins.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the turning tool is fully de-energized and removed from the machine spindle before servicing clamp hardware. Use a calibrated 2mm hex key to install the lock pin to the clamp manufacturer's specified engagement. Do not use power drivers on small-thread fasteners of this type, as overtorquing may strip the thread or damage the clamp body.
