Labfintom Cordless Rivet Nut Gun Compatible with DeWalt 20V — Brushless Motor, 3 Sizes (1/4", 5/16", 3/8")

The Labfintom Cordless Rivet Nut Gun is a battery-powered, brushless motor tool designed to install 1/4", 5/16" and 3/8" rivet nuts quickly and consistently, and it accepts DeWalt 20V MAX batteries for convenient power sharing.

Built for garage mechanics, metalworkers and DIYers who need a portable, reliable riveting solution, this kit combines a brushless motor, three nut heads, spare mandrels, and accessories in a compact carrying case. It is engineered specifically for carbon steel and aluminum rivet nuts — not stainless steel — and includes Auto and Manual modes with a memory function for repeating the same stroke and tension settings. The package also supplies 20 rivet nuts, a step drill bit, lubricant, and extra mandrels so you can start work right away (battery sold separately).

How does the brushless motor improve performance?

The brushless motor provides smoother, more efficient power delivery than brushed variants, reducing heat and extending tool life. That translates to steadier stroke control across the three supported nut sizes and fewer maintenance needs.

• Consistent torque for repeatable rivet compression
• Lower heat and longer runtime per battery charge
• Reduced internal wear and longer motor lifespan

What sizes and materials can I use with this rivet nut gun?

This tool is optimized for 1/4", 5/16" and 3/8" rivet nuts in carbon steel and aluminum only. It is not compatible with stainless steel rivet nuts or conventional solid rivets, so confirm the rivet nut material before installation to avoid problems.

• Includes nut heads for 1/4", 5/16", 3/8" sizes
• Supplied rivet nuts suited to carbon steel and aluminum
• Not designed for stainless-steel nuts or pop rivets

How do the Auto and Manual modes help different jobs?

Auto Mode completes a full riveting cycle with one trigger pull, speeding up repetitive work like chassis or cabinet assembly. Manual Mode gives you step-by-step control for delicate or cramped jobs. A built-in memory stores your last mode and tension setting so you don’t have to reprogram for recurring tasks.

• Mode 2 (Auto) for fast, repeatable cycles
• Manual for precision and odd-angle work
• Memory function retains last gear and tension setting

What safety and setup steps should I follow before use?

To avoid installation issues, always confirm rivet nut material and set the forward/reverse switch to reverse before operating. The tool is intended only for rivet nuts; improper fasteners or extreme tension settings can damage parts or the tool. Batteries sold separately — it accepts common DeWalt 20V MAX models.

• Verify nut material: carbon steel or aluminum only
• Place switch in reverse before initial use
• Choose tension by nut size: 1/4" (5–10), 5/16" (15–30), 3/8" (30–45)

Who this is for: The Labfintom cordless rivet nut gun is aimed at auto repair professionals, metal fabricators, HVAC installers, and serious home DIYers who need a portable, battery-powered solution for installing threaded rivet nuts. It’s especially useful if you already own DeWalt 20V batteries and want to share power across tools. If you require work with stainless steel rivet nuts or solid rivets, choose a different tool purpose-built for those materials.
