Value Collection 6-999-270 Indexable Lock Screw

Product Description

The VALUE COLLECTION 6-999-270 is a lock screw designed to secure indexable inserts in square-shoulder face mills and shell mills. This fastener holds cutting inserts firmly in the tool pocket during machining operations, preventing movement under cutting loads. It is a direct replacement-style component used during routine insert changes on indexable milling toolholders. Weighing approximately 0.28 pounds, it is a compact, precision-threaded screw suited for maintenance of indexable milling tools in production and job-shop environments.

This lock screw is used in metalworking and machining applications where indexable square-shoulder face mills and shell mills are in service. It is installed during insert replacement cycles, a routine maintenance task performed by machinists, toolroom technicians, and CNC operators. It is sold individually per package, with a minimum order quantity of 5 units, making it suitable for stocking as a consumable replacement fastener.

Installation Notes

Installation is performed by machinists or toolroom technicians during indexable insert replacement. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before servicing any toolholder. Use the correct Torx or hex key driver specified by the toolholder manufacturer to avoid stripping the screw head. Do not overtighten, as lock screws for indexable inserts are precision-threaded components that can be damaged by excessive torque.
