Labfintom Cordless Rivet Nut Gun Compatible with DeWalt 20V Battery — Brushless Motor, Auto & Manual Mode

The Labfintom Cordless Rivet Nut Gun is a brushless, battery-powered tool designed to install 1/4", 5/16" and 3/8" rivet nuts quickly and consistently when used with carbon steel or aluminum fasteners.

This compact electric rivet nut tool pairs a brushless motor with Dewalt 20V compatibility to give DIYers and mechanics a portable, repeatable way to set threaded rivet nuts into metal panels, frames and assemblies. The kit arrives with three nut heads, five spare mandrels, 20 rivet nuts, a step drill bit, lubricant and a tough carry case so you can start jobs right away (battery sold separately). Built-in auto and manual modes plus memory for your last setting streamline both one-off repairs and high-volume runs.

How does this rivet nut gun save time on automotive or sheet-metal work?

The Labfintom tool finishes a full rivet-nut cycle in Auto Mode with a single trigger pull, eliminating repetitive manual cranking. The brushless motor delivers steady pull force across sizes so each nut seats cleanly when tension settings match the fastener. For projects with many anchors this reduces fatigue and maintains consistent thread engagement.

• Auto Mode completes a rivet cycle automatically for faster repeat installs
• Memory function recalls last mode and tension to avoid constant readjustment
• Included step drill saves time prepping accurate hole sizes
• Compact form and Dewalt 20V battery compatibility allow quick swap between tools

Which rivet nuts and materials work with this tool?

Use this gun only with carbon steel or aluminum rivet nuts sized 1/4", 5/16" and 3/8"; it is not suitable for stainless steel rivet nuts or traditional solid rivets. Matching the rivet nut material and the correct tension range avoids deformation or loose installs. Follow the tension guidance for each size to get reliable clamping and thread strength.

• Supported nut diameters: 1/4", 5/16", 3/8"
• Material compatibility: carbon steel and aluminum rivet nuts only
• Not for stainless steel rivet nuts or pop rivets
• Tension ranges: 1/4" (5–10), 5/16" (15–30), 3/8" (30–45)

What controls and settings give precise results?

The gun offers Auto Mode for one-trigger cycles and Manual Mode for controlled strokes; switching modes requires a two-second press of the plus/minus buttons. A built-in memory stores your last gear and tension, so repetitive work remains consistent without reprogramming. Adjust tension up or down to match nut size and sheet thickness; too much or too little tension affects the joint.

• Auto Mode: single-trigger full cycle for speed
• Manual Mode: incremental control for delicate installs
• Memory chip saves previous mode and tension settings
• Visible tension values correspond to nut size ranges on the tool

What’s included and what should I expect from the kit?

The package supplies three nut heads for the supported sizes, five spare mandrels, 20 matching rivet nuts, a step drill bit, lubricant to reduce wear and a sturdy carry case for transport and storage. The tool is tuned for rivet nuts only and will not set rivets; batteries are intentionally not included so you can use existing compatible Dewalt 20V packs.

• 3 nut head sizes (1/4", 5/16", 3/8") and 5 spare mandrels
• 20 rivet nuts, step drill bit, lubricant and compact carry case
• Dewalt 20V MAX battery compatible (battery not included)
• Brushless motor for longer life and consistent pull force

Who is this for: The Labfintom Cordless Rivet Nut Gun is aimed at automotive technicians, metal fabricators, HVAC installers, cabinet makers and dedicated DIYers who need a portable, repeatable solution for installing threaded rivet nuts in carbon steel or aluminum. If you already use Dewalt 20V batteries, the tool slots into your workflow without extra battery purchases; if you need stainless-steel fasteners or solid rivet work, choose a tool designed for those materials instead.
