The KENNAMETAL 1019380 is a clamp screw designed for indexable cutting tool assemblies used in milling and turning applications. It features a 5/16-24 thread size and a 5/32-inch hex socket drive, providing a secure, repeatable clamping force on indexable inserts. This type of fastener is a consumable component in any toolroom or production machining environment and is replaced regularly during insert changes. Machinists and tooling technicians rely on OEM-spec clamp screws to maintain proper insert seating and cutting geometry throughout the tool life cycle.
This screw is suited for use with indexable milling and turning toolholders that require a 5/16-24 clamp screw with a hex socket drive. It is commonly used in both production and job-shop machining settings where KENNAMETAL indexable tooling systems are in service. The hex socket design allows for controlled torque application with a standard T-handle or torque wrench, minimizing the risk of over-torquing and insert or pocket damage.
Designed for use with KENNAMETAL indexable toolholders requiring a 5/16-24 clamp screw with a 5/32-inch hex socket drive, compatible with clamp-style insert retention in milling and turning applications.
Installation should be performed by a qualified machinist or tooling technician. Before replacing the clamp screw, ensure the machine spindle is fully stopped and the toolholder is secured in a safe position. Use a calibrated torque wrench with the appropriate 5/32-inch hex key to apply the manufacturer-recommended torque — refer to the toolholder documentation for the correct value. Never reuse visibly damaged or stripped clamp screws, as improper insert clamping can result in insert ejection during cutting.
