JiGiU 16" Rivet Nut Tool Kit: Heavy-Duty Nutsert Gun with 7 Mandrels and 110 Rivet Nuts

What it is this Rivet Nut Tool Kit is a complete hand rivet nut gun designed for durable, reliable fastening across metal, plastic and composite parts. On paper, it combines a 16-inch lever, a quick-change head, and a full set of mandrels and rivet nuts to cover common sizes from M3 up to M12. In practice, it aims to be a practical solution for workshop and field tasks where a portable, no-electric-power rivet system is preferable. The kit includes seven mandrels (covering metric sizes from M3 to M12) and 110 rivet nuts, all housed in a sturdy carrying case. The mandrel storage in labelled mini boxes should help you locate the right size quickly, a small but meaningful convenience when you’re mid-project.

How it’s built and how it feels The tool body is crafted from heat-treated high-carbon steel intended to resist corrosion and minimise distortion. A U-shaped rivet arm is pitched as a design choice to boost reliability and reduce the chance of bending under strain. The PVC sleeve on the handle is described as a labour-saving feature, purportedly helping to cut effort by up to 30% compared with some similar tools. If you’re regularly tightening rivnuts, that kind of improvement can translate into fewer pauses and quicker cycles, though real-world results often depend on material and technique.

What stands out, and what gives you pause For a kit like this, the practical strengths lie in the breadth of sizes and the portability provided by the case. Your benefit, on the page, is the ability to tackle a wide range of rivet nut jobs in one go without needing separate mandrels or an extra toolkit. On the other hand, as a hand tool, it will naturally require physical effort, and you may still want an electric option for high-volume work. If your projects lean heavily towards very large or thick-walled sections, you might notice the limits of a 16-inch lever in terms of leverage or speed.

Suitable uses and ideal buyers It’s aimed at hobbyists, small workshops, bike and automotive projects, and light fabrication tasks where you need to fasten rivnuts to sheet metal or plastic components. This kit could suit someone who values a broad size range in a compact package and who doesn’t want to rely on powered tools. If you frequently work with materials beyond common automotive gauges, you may prefer to check compatibility with your typical substrates before purchasing.

When it makes sense to buy and when to pass It makes sense to buy if you want a ready-to-go rivet nut solution with multiple mandrels, a carrying case, and a substantial number of rivet nuts included. It may be less compelling if you prioritise maximum ease or speed and are performing high-volume production tasks, in which case a powered tool or a model with higher cycle counts could be more efficient. Consider your typical thickness, material type, and required rivet nut sizes (M3–M12) to ensure this kit aligns with your needs.

What to check before buying This kit promises a quick-change head design—confirm you understand how to swap heads and mandrels safely. Look at the weight and balance you’ll be handling during longer sessions, and gauge whether the 30% labour-saving claim holds up in your own work when factoring in material hardness and access. Also, ensure the carrying case is sturdy enough for your workspace and travel needs, and check that the included rivet nuts match the sizes you use most often.

Practical usage example A common scenario is attaching bicycle bottle cages or mounting brackets to a metal frame where a clean, flush rivet nut finish is required. With the 16-inch reach, you can work from a comfortable distance and grip, changing mandrels for different rivet sizes as you go without hunting for tools.

What you get in the box A robust carrying case housing the rivet nut gun, 7 interchangeable mandrels (M3, M4, M5, M6, M8, M10, M12) and 110 rivet nuts, plus labelled mini plastic boxes for each mandrel.

FAQ (based on available information)

• What sizes does the mandrel set cover? M3 to M12.
• Is the head designed for quick changes without extra tools? Yes, described as a quick-change head design.
• How many rivet nuts are included? 110 rivet nuts.

Is it worth it? Buying verdict

It makes sense if you need a broad, ready-to-go rivet nut solution for a mix of sheet metal and plastic parts and you value a portable kit with organised storage. It may not be the best option if your workflow relies on rapid high-volume production or if you frequently work in areas that require very high-strength fastenings beyond what a hand tool can comfortably deliver. If you prioritise durability, a wide size range, and a practical carrying solution, this JiGiU kit offers a pragmatic balance between capability and portability.
