Heavy-Duty Build for Precise Manual Control

Crafted from high-strength carbon steel, these mandrels are built to withstand repeated heavy use without stripping or bending. The manual operation gives you direct tactile feedback, ensuring a secure, clean installation every time without the risk of over-tightening often associated with power tools.

Do I need a power drill to use this kit?

No, this kit is designed specifically for manual operation using the included wrenches and gun body. This allows for greater precision and control during installation.

What materials can I use these rivet nuts on?

They are ideal for thin materials where tapping a thread is not possible, such as sheet metal (steel, aluminum), plastic panels, and fiberglass pipes.

Are the mandrels durable for repeat use?

Yes, the mandrels are constructed from high-strength carbon steel, designed to resist wear and provide long-lasting performance even under heavy manual use.
