Rego-fix 3516.60000 ER16 Clamping Nut

Product Description

The REGO-FIX 3516.60000 is an ER16 clamping nut designed to secure ER16 collets in compatible toolholders during machining operations. It threads onto the toolholder nose and applies uniform clamping force across the collet, maintaining accurate tool position under cutting loads. Weighing 0.05 pounds, this is a direct replacement component intended for shops and technicians maintaining ER16 toolholding systems. Machinists, toolroom technicians, and CNC setup personnel are the primary installers of this type of hardware.

The ER16 clamping nut fits into ER16 toolholding systems found in CNC machining centers, manual milling machines, and drill presses. It is a standard replacement item suited for production and maintenance environments where worn or damaged clamping nuts need to be swapped out to restore proper collet clamping performance. This nut is sold individually, making it practical for single-unit replacement without requiring a full toolholding assembly.

Key Features

• Designed for the ER16 collet series, providing proper thread engagement and clamping force
• Lightweight at 0.05 pounds, minimizing added mass at the spindle nose
• Single-unit packaging supports direct replacement without excess inventory
• Compatible with the standard ER16 toolholding interface used across multiple machine platforms

Compatibility

Designed as a replacement clamping nut for ER16 collet toolholding systems. Specific machine or toolholder model compatibility should be verified against the ER16 thread specification before installation.

Installation Notes

Installation is performed by machinists or toolroom technicians using a standard ER collet nut spanner wrench. The toolholder must be removed from the spindle and all cutting forces relieved before servicing the collet assembly. The collet should be seated correctly in the clamping nut before threading the assembly onto the toolholder nose. Do not over-tighten without reference to the toolholder manufacturer's torque guidance.
