Kennametal 1021567 Lock Pin 2.5mm Hex M6.3x1 Thread

Product Description

The KENNAMETAL 1021567 is a lock pin designed to secure insert clamps on indexable turning tool assemblies. With a 2.5mm hex socket drive and M6.3x1 thread, this pin provides the precise mechanical retention needed to keep cutting inserts stable during turning operations. It is used by machinists and toolroom technicians working with indexable toolholders on CNC lathes and manual turning centers. The pin replaces worn or damaged fastening hardware to restore proper clamping force and prevent insert movement under cutting loads. Correct lock pin installation is critical to dimensional accuracy and insert life.

This lock pin is intended for use in indexable turning tool systems where insert clamps require threaded retention hardware. It is a direct-fit replacement component for CKM23LP clamp assemblies. Typical applications include external turning, facing, and profiling operations on production lathes in both job shop and industrial manufacturing environments. The small package quantity makes it practical for maintenance kits and toolcrib replenishment.

Key Features

• 2.5mm hex socket drive for standard hex key installation and removal
• M6.3x1 thread for precise engagement with compatible clamp bodies
• Designed for CKM23LP clamp compatibility
• Compact, lightweight form factor at approximately 0.002 pounds per pin
• OEM-style replacement maintains original clamping performance

Compatibility

Designed for use with CKM23LP clamps on KENNAMETAL indexable turning tool assemblies. Consult your toolholder documentation to confirm thread and hex socket specifications before installation.

Installation Notes

Lock pin replacement is typically performed by a machinist or toolroom technician. Ensure the turning tool assembly is fully removed from the machine spindle and any power or coolant supply is shut off before servicing clamp hardware. Use a calibrated 2.5mm hex key to install and seat the pin without overtightening, as cross-threading or excessive torque can damage the clamp body threads. Inspect the mating clamp and insert seat for wear before reinstalling.
