Carmex S40 Insert Screw Indexable Thread Mill

Product Description

The CARMEX S40 is an insert screw designed to secure indexable inserts in compatible tooling systems. It functions as a clamping fastener, holding the cutting insert firmly in place during machining operations. The S40 is classified as an insert screw with a screw type designation for use with clamp-style retention, and it is specifically suited for indexable thread mill tooling. Machinists and tooling technicians working with indexable threading systems rely on hardware like the S40 to maintain insert position and cutting accuracy under load.

The S40 is intended for use in indexable thread milling applications where insert-securing hardware must be replaced or restocked. It is compatible with clamp-style indexable tool bodies designed to accept this screw type. Thread milling operations in CNC machining environments across job shops and production facilities are the typical install context. This part is sold individually but carries a minimum order quantity of 10 units, making it practical for tooling cribs and maintenance stock.

Key Features

• Insert screw type designed for indexable thread mill tooling
• Compatible with clamp-style insert retention systems
• Maintains insert seating and positioning under cutting loads
• Stocked in quantity for tooling crib replenishment (MOQ 10)

Compatibility

Designed for use with clamp-style indexable thread mill tool bodies that accept the S40 insert screw. Verify compatibility with the specific tool body manufacturer and body designation before ordering.

Installation Notes

Insert screws should be installed and removed by a qualified machinist or tooling technician using the correct Torx or hex key driver specified by the tool body manufacturer. Always power down and lock out the machine before changing inserts or insert hardware. Do not overtighten insert screws, as this can damage the screw threads or the tool body pocket. Replace insert screws at the first sign of thread wear or deformation to maintain cutting accuracy.
