Labfintom Cordless Rivet Nut Gun — DeWalt 20V Compatible, Brushless Motor, 1/4"–3/8" Nut Heads, Auto & Manual

The Labfintom Cordless Rivet Nut Gun is a battery-powered, brushless rivet-nut installer compatible with DeWalt 20V batteries that fits 1/4", 5/16", and 3/8" rivet nuts for automotive and metalwork tasks.

This compact electric rivet nut tool brings fast, repeatable nut installation to garages, workshops, and DIY projects. Built around a brushless motor for consistent torque and longer runtime, the unit works with common carbon steel and aluminum rivet nuts and accepts DeWalt 20V MAX cells so you can share batteries with your existing toolset. The kit bundles three nut heads, spare mandrels, a step drill bit, lubricant, 20 matching rivet nuts, and a molded carry case for organized storage and transport.

How does this tool speed up rivet nut installation?

The Labfintom gun offers an Auto Mode that completes a full riveting cycle with a single trigger pull, cutting cycle time on repetitive jobs. When you need precision, Manual Mode lets you control the stroke for delicate setups. A memory function preserves your last mode and tension setting so the tool is ready to repeat the same result without reconfiguration.

• Auto Mode completes cycles automatically for rapid, consistent installations.
• Manual Mode allows stepwise control for precise or delicate work.
• Memory function stores last mode and tension settings to save setup time.
• Brushless motor provides steady power with less maintenance and longer life.

Which rivet nut sizes and materials are supported?

This tool is designed specifically for 1/4", 5/16", and 3/8" rivet nuts and performs best with carbon steel and aluminum nuts. It is not intended for stainless steel rivet nuts or conventional rivets; using unsupported fasteners can cause poor installation or damage. Check rivet nut material before starting to ensure reliable outcomes.

• Supported sizes: 1/4", 5/16", 3/8" (three included nut heads).
• Recommended materials: carbon steel and aluminum rivet nuts only.
• Not compatible with stainless steel rivet nuts or standard rivets.
• Includes 20 matching rivet nuts to get you started.

What power and tension settings should I use for different jobs?

The brushless motor delivers adjustable tension to match nut size and material. Labfintom provides recommended tension ranges to avoid over-compression or loosening: lower ranges for 1/4" nuts, mid ranges for 5/16", and higher ranges for 3/8" installations. Always test on scrap metal to confirm the correct setting before working on finished surfaces.

• 1/4" rivet nuts: lower tension range (gentler compression).
• 5/16" rivet nuts: medium tension for standard applications.
• 3/8" rivet nuts: higher tension settings for larger fasteners.
• Use trial installations to fine-tune tension and prevent damage.

What accessories and extras come with the kit?

The package includes essential consumables and spares so you can start jobs immediately and maintain uptime. Multiple mandrels and a step drill bit help prepare holes and replace worn parts, while the included lubricant reduces wear on moving components. A durable molded carry case organizes everything for transport and storage.

• Three nut heads for 1/4", 5/16", and 3/8" rivet nuts.
• Five replacement mandrel rods and a step drill bit for hole prepping.
• Lubricant for reduced wear and 20 starter rivet nuts included.
• Sturdy compact carry case keeps tools and accessories organized.

Who is this for: The Labfintom Cordless Rivet Nut Gun is made for mechanics, fabricators, HVAC installers, metal furniture assemblers, and serious DIYers who need a portable, repeatable rivet-nut solution. It suits users who already own DeWalt 20V batteries or who value a brushless motor for longer life and consistent torque. Avoid this tool if your projects require stainless steel rivet nuts or conventional rivets.
