The SECO 02436243 is a lock screw designed to secure indexable inserts in milling toolholders. It uses a Torx Plus drive, which provides improved torque transfer and reduced cam-out compared to standard Torx fasteners. This screw is a consumable hardware component that is replaced as part of routine insert maintenance on milling setups. Machinists and toolroom technicians install it when swapping or indexing carbide inserts, keeping cutting tools properly seated and torqued for accurate, repeatable cuts.
This lock screw is intended for use with indexable milling toolholders that accept insert-clamping hardware. It is a direct replacement component suited to production milling environments, job shops, and maintenance toolrooms where indexable cutting tools are regularly serviced. The manufacturer catalog number associated with this part is C46017-T20P, which may assist in cross-referencing with SECO toolholder documentation or insert clamp hardware lists.
Designed as an OEM-style replacement lock screw for indexable milling toolholders that require Torx Plus drive insert-clamping hardware. Confirm thread size and drive specification against the host toolholder documentation before ordering.
Installation is performed by machinists or toolroom technicians during routine insert indexing or replacement. Ensure the milling spindle is fully stopped and the machine is locked out before accessing the toolholder. Use the correct Torx Plus bit to avoid fastener damage, and follow the toolholder manufacturer's torque specification for the screw size. Do not substitute a standard Torx driver, as the Plus profile requires a matched bit for proper engagement.
