Iscar 7005583 Indexable Cap Screw Torx M4 X 0.7

Product Description

The ISCAR 7005583 is a countersunk-head cap screw designed for indexable toolholders in turning applications. It uses a Torx drive and M4 x 0.7 thread to secure clamps and inserts in DDJN-style toolholders. At 0.3346 inches (8.50 mm) overall length, this screw is engineered to the tight tolerances required for repeatable insert seating in production turning environments. Installation requires an HW 2.5 key driver. This fastener is a direct service component within the Isoturn series and is typically replaced as part of routine toolholder maintenance by machinists and toolroom technicians.

This cap screw is used in CNC and manual turning setups where DDJN-style toolholders are employed. It is compatible with both clamp-style and insert-style mounting hardware within the Isoturn series. Typical install scenarios include production turning cells, job shop lathes, and toolroom setups requiring periodic insert changes or clamp replacement. The screw is sold individually with a minimum order quantity of 5 units, making it practical to stock as a consumable fastener alongside indexable insert inventory.

Key Features

• M4 x 0.7 thread size for precise engagement in DDJN toolholder bores
• Countersunk head profile seats flush for proper clamp and insert clamping force
• Torx drive reduces cam-out risk during high-frequency insert changes
• HW 2.5 key driver compatible — standard Isoturn series tooling key
• 8.50 mm (0.3346 inches) overall length suits standard DDJN holder geometry
• Lightweight at 0.01 pounds — suitable for bulk stocking as a consumable

Installation Notes

Installation is performed by machinists or toolroom technicians as part of insert changes or toolholder service. Always power down and lock out the machine spindle before servicing indexable toolholders. Use only the specified HW 2.5 Torx key driver to avoid damaging the screw head or toolholder bore. Do not substitute fasteners of different thread pitch or head geometry, as improper fasteners can compromise clamping force and insert seating accuracy.
