Nutsert Mandrel (4 mm).

Key Features:

• Nutsert Mandrel: This is a specialized tool component used to install nutserts (also known as rivet nuts or threaded inserts).
• 4 mm Size: This indicates the mandrel is designed for installing 4 mm nutserts.
• Threaded Ends: The mandrel has threaded ends for attaching to a nutsert installation tool and for engaging with the nutsert itself.
• Knurled Center Section: The center section of the mandrel is knurled, providing a better grip for tightening and loosening.
• Metal Construction: The mandrel is made of metal, likely steel or a hardened alloy, for strength and durability.

Function:

A nutsert mandrel is used in conjunction with a nutsert installation tool to:

1. Thread the nutsert onto the mandrel.
2. Insert the nutsert into a pre-drilled hole in a workpiece.
3. Pull the mandrel back, deforming the nutsert and creating a threaded insert in the workpiece.
