Allied Machine IS-10-1 Cap Screw Torx Plus M3 Thread

Product Description

The ALLIED MACHINE AND ENGINEERING IS-10-1 is a flat head cap screw designed specifically for securing indexable inserts in drilling toolholders. Built to the IS-10-1 industry standard, this screw features a Torx Plus drive for improved torque transfer and reduced cam-out during insert changes. The M3 thread size is compatible with standard indexable tooling systems. At 0.01 pounds per unit, it is a lightweight but precision-critical fastener that keeps inserts locked securely under cutting loads. This part is installed and replaced by machinists and tooling technicians during routine insert changes or toolholder maintenance.

This cap screw is used in indexable drilling toolholders that accept IS-10-1 standard insert screws. It is suited for production machining environments where inserts are swapped frequently and consistent clamping force is required. The Torx Plus drive type reduces tool wear on the drive interface, which matters in high-cycle insert replacement workflows. Sold individually per package with a minimum order quantity of 10 units, making it practical to stock as a consumable tooling component.

Designed as an OEM-style replacement cap screw for indexable drilling toolholders that conform to the IS-10-1 industry standard with M3 thread insert pockets.

Installation Notes

Installation is performed by a machinist or tooling technician during insert changes or toolholder servicing. Ensure the toolholder is removed from the spindle and the machine is powered down and locked out before servicing insert hardware. Use the correct Torx Plus key driver to avoid stripping the drive recess. Do not exceed the torque specification provided by the toolholder manufacturer for M3 insert screws.
