Nikcole Mini-systems M3X8.06MM Thd Indexable Cap Screw

Product Description

The NIKCOLE MINI-SYSTEMS M3X8.06MM THD is a cap screw engineered for securing indexable inserts in precision cutting toolholders. This fastener uses a T8 Torx drive and an M3 x 8 thread, providing reliable clamping force for indexable tooling applications. At 0.63 pounds per package and an overall length of 8.00 millimeters, this screw is sized for direct OEM-style replacement or initial build-out of indexable tool assemblies. Machinists and toolroom technicians install these screws when mounting or rotating carbide inserts on grooving, threading, tracing, and turning toolholders.

This cap screw is suited for use in CNC and manual lathe setups where indexable insert toolholders are standard. It is applicable across grooving, threading, tracing, and turning operations. The T8 Torx drive minimizes cam-out during insert changes, which matters in high-cycle production environments where inserts are rotated or replaced frequently. The M3 x 8 thread size is a common fastener spec across a range of indexable toolholder platforms used in metalworking shops.

Key Features

• T8 Torx drive reduces cam-out risk during insert indexing
• M3 x 8 thread size for secure insert clamping
• 8.00 mm overall length fits standard indexable toolholder insert pockets
• Compatible with T8 key and driver tools
• Applicable to grooving, threading, tracing, and turning toolholder types

Compatibility

Designed for use with indexable insert toolholders requiring an M3 x 8 cap screw with a T8 Torx drive. Compatible insert and toolholder types include grooving, threading, tracing, and turning. Requires a T8 key driver for installation.

Installation Notes

Installation is performed by toolroom technicians or machinists. Power down and lock out the machine before accessing the toolholder or rotating inserts. Use a calibrated T8 Torx key driver to seat the screw - do not use impact tools on indexable insert screws, as over-torquing can damage the insert pocket threads. Replace screws showing signs of thread wear or drive socket damage to maintain consistent insert clamping.
