Iscar 7000836 Cap Screw T7 Torx M2.2 X 0.45 Dct

Product Description

The ISCAR 7000836 is a countersunk-head cap screw engineered for securing indexable inserts in DCT-style toolholders. It features an M2.2 x 0.45 thread and a T7 Torx drive, requiring a T-7/51 key driver for installation. At 0.18 inches (4.60 mm) overall length and 0.05 pounds, this fastener is a precision-fit component used in the Pre-Thread series. Machining professionals and toolroom technicians rely on this screw to maintain insert clamping integrity across high-speed milling, boring, and drilling operations. Its countersunk head profile seats flush with the toolholder pocket to avoid interference with the cutting path.

This cap screw is suited for use in ball nose end mill, boring bar, and drilling toolholders configured for indexable insert systems. It is compatible with DCT toolholder styles and designed for the Pre-Thread series. Typical applications include CNC turning centers, machining centers, and multi-operation setups where frequent insert changes demand reliable, repeatable fastener performance. Replacement of worn or damaged clamping screws is a routine part of insert toolholder maintenance in production and job-shop environments.

Compatibility

Designed for DCT-style toolholders in the Pre-Thread series. Confirmed compatible inserts include AOMT 030204-N-30DT, AOMT 030204-N-45DT, and AOMT 060204-45DT. Suitable for ball nose end mill, boring bar, and drilling indexable tool types.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine before changing inserts or clamping screws. Use only the specified T-7/51 Torx key driver to seat the screw — use of incorrect drivers risks stripping the fastener head. Follow the toolholder manufacturer's torque guidelines and inspect threads for wear or contamination before reinstalling.
