Mitsubishi 160291 Shim Screw Indexable M5 Thread

Product Description

The MITSUBISHI 160291 is an M5 thread shim screw designed for use with indexable cutting tool assemblies. Shim screws secure the shim beneath an indexable insert, maintaining precise seating and preventing movement during cutting operations. This fastener measures 0.276 inches in overall length with a head size of 0.248 inches and weighs approximately 0.01 pounds. It is a standard replacement hardware component used by machinists and tooling technicians working with MITSUBISHI indexable toolholders and similar insert-based cutting systems.

This shim screw is appropriate for metalworking and machining environments where indexable insert tooling is in service, including turning, milling, and boring applications. It is sold individually and is suited for shops maintaining indexable toolholder assemblies that require periodic hardware replacement due to wear, damage, or loss of the original fastener.

Key Features

• M5 thread size for compatibility with standard indexable toolholder shim pockets
• Overall length of 0.276 inches for precise fit within the toolholder body
• Head size of 0.248 inches for proper drive and seating
• Lightweight at 0.01 pounds, consistent with precision machining fastener standards
• Sold in single-unit quantity for targeted hardware replacement

Compatibility

Designed as a shim screw replacement for indexable toolholders requiring M5 thread hardware. Specific toolholder compatibility should be verified against the toolholder documentation before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable insert systems. Ensure the toolholder is removed from the machine and all power is locked out before servicing the insert pocket and shim hardware. Use the correct driver to avoid stripping the screw head, and do not overtighten, as shim screws in indexable systems have defined seating requirements specified in the toolholder documentation.
