NEXTACK 1/4" Blind Rivet Gun Kit NT300 — 350 Rivets, 5 Nosepieces, Two-Handed Leverage

The NEXTACK NT300 is a heavy-duty 1/4" blind pop rivet gun kit that crimps stainless and aluminum blind rivets up to 1/4" (6.4mm) and includes 350 assorted rivets and five interchangeable nosepieces.

This kit brings a professional-grade hand tool and a comprehensive assortment of fasteners into one compact case, built for both serious DIYers and tradespeople. The NT300 combines long, two-handed ergonomic handles for leverage, hardened jaws for reliable gripping, and a removable mandrel catcher for cleaner work. Everything stores neatly in a labeled, compartmented case so you can grab the right size rivet fast while on the job or at the workshop bench.

How much force and leverage does the NT300 provide for 1/4" rivets?

The NT300 uses long, two-handed handles to deliver the mechanical advantage needed for 1/4" blind rivets without resorting to air tools. The cold-forged #50 carbon steel handle and aluminum alloy body resist deformation, while the heat-treated SCM435 steel jaws ensure strong, consistent grip on each mandrel.

• Two-handed ergonomic handles for added leverage and reduced user fatigue.
• Cold-forged carbon steel handle for strength under repeated use.
• Heat-treated jaws (HRC52-63) for secure mandrel pull and long life.

What comes in the kit and how do I pick the right nosepiece?

The kit contains five interchangeable nosepieces sized for common blind rivets (1/8", 3/32", 5/32", 3/16" and 1/4") plus 350 aluminum rivets in eight popular lengths. Nosepieces swap without tools so you can change sizes on-site in seconds and the labeled case helps you locate the correct rivet quickly.

• Five tool-free nosepieces matching common rivet diameters for fast swaps.
• 350 mixed-size aluminum blind rivets to cover a broad range of projects.
• Labeled, compartmented carrying case keeps parts organized and transportable.

Is the NT300 durable and easy to maintain on busy jobsites?

Yes — the NT300 was built for repeated field use. The rugged aluminum alloy body resists corrosion, while hardened jaws and a robust handle withstand heavy pulling. The modular design makes disassembly and cleaning straightforward, and the integrated mandrel catcher holds spent stems for tidy disposal.

• Aluminum alloy housing for corrosion resistance and lighter weight.
• Removable mandrel catcher keeps work area clean and makes disposal simple.
• Tool-free disassembly and modular components simplify maintenance and part replacement.

What should I know about jams and compatibility with rivet types?

Jams are uncommon when the correct nosepiece is used and the tool is maintained, but the NT300 includes a straightforward quick-fix procedure. If a mandrel becomes stuck, swapping to the next larger nosepiece and opening the handles allows the jammed stem to drop into the catcher. Note: this tool is designed for blind pop rivets and is not intended for threaded rivet nuts.

• Swap to a larger nosepiece and open handles to clear jammed stems safely.
• Built-in catcher captures spent mandrels for safe and tidy disposal.
• Not suited for threaded rivet nut installation—use only blind pop rivets.

Who is this for? The NEXTACK NT300 kit is ideal for homeowners tackling repairs, fabricators and metalworkers needing a reliable hand riveter, and professionals on jobsites who want a portable, complete rivet assortment. It suits any project joining metal, plastic or leather where blind rivets are appropriate — from gutter repairs and van/RV build-outs to general shop and DIY tasks. If you need a durable, organized rivet solution with straightforward maintenance and strong pull capacity for up to 1/4" blind rivets, this kit covers the essentials.
