Lytool Rivnut Tool Kit 13" – Hand Rivet Nut Setter with 70 Rivet Nuts (M3 to M12) & 7 Mandrels
Product description
The essentials
If you’re dealing with sheet metal, brackets, or DIY fabrication where you want strong, repeatable threaded fixing points, a rivet nut (rivnut) tool is the straightforward route. The Lytool Rivnut Tool Kit 13" is a hand rivet nut setter that comes with 7 interchangeable mandrels and 70 rivet nuts, covering sizes from M3 up to M12. On paper, that’s the kind of kit you buy once and use across a range of projects rather than hunting for the right size every time.
It’s a tool designed around manual operation, with a longer lever arm for power transmission. That matters more than people expect: when you’re setting rivet nuts, you’re asking the tool to do real mechanical work, not just hold parts in place.
Key points you’ll care about
The main reason this kit makes sense is its spread of sizes. You get multiple mandrels and a bundle of rivet nuts, with each size listed as 10 pieces (M3, M4, M5, M6, M8, M10, M12). So for common builds—anything from body panels and bicycle attachments to furniture and workshop assemblies—you’re not limited to a single thread size.
It also leans into durability claims: the mandrels are described as chrome steel (heat treated), and the arm is 45 carbon steel, with resistance to corrosion and deformation. The kit is supplied in a solid case/bag setup aimed at storage and portability, with accessories packed close to their position to reduce movement and scuffs.
That said, it’s not perfect for every situation. If you regularly need a high-volume production workflow, or you want a faster “set and forget” rhythm all day long, a manual hand tool can feel slower than powered alternatives.
What stands out in use
In practical terms, a rivet nut setter like this is for converting a plain hole in thin metal (or structured panels) into a reusable threaded anchor. A typical use looks like this: you drill the correct pilot hole, insert the rivet nut, choose the correct mandrel size (for the thread you need), then pull/operate the hand tool to flare and lock the rivet nut in place.
Because the mandrels are interchangeable, the kit is geared toward switching sizes without buying separate setters. That’s genuinely useful when you’re working on multiple stages of a project—say, you start with M4 for a bracket, then later move to a larger fixing point for added strength.
And for “light industrial” and modification work—your listing specifically calls out off-road/Jeep modifications—this kind of kit can be the middle ground between DIY and proper shop capability.

Where it shines (and where it may not)
If you want a compact kit that covers several common rivet nut sizes, this one is easy to justify—especially if you don’t want to build your basket of tools and consumables gradually. It also suits people who value tidy storage: having mandrels and nuts together in one kit reduces the “where did I put the right mandrel?” hassle.
However, it may not be the best match if you’re trying to maximise throughput or if your work is heavily specialised beyond the listed sizes. The kit covers M3–M12, but if your projects demand other thread sizes or you expect to set rivet nuts continuously for long sessions, you may find a manual approach a bit limiting.
It’s worth noting too that the description talks to durability and corrosion resistance, but it doesn’t give details like exact working range, drilling guidance, or compatibility with specific rivnut materials—so you’ll want to be confident about your hole size and material thickness before committing.
Buying verdict
Final verdict
It’s worth considering this Lytool Rivnut Tool Kit 13" if you want one hand rivet nut setter that covers multiple sizes (M3 to M12) with 7 mandrels and a decent bundle of rivet nuts included. It suits practical workshop use—repairs, modifications, and everyday builds—where you want threaded fixing points in sheet metal without relying on welding.
You may want to skip it if your work is high-volume, time-critical, or you need a broader specification than the kit covers based on the information given. In other words, if you’re expecting a production-style tool or you frequently work outside M3–M12, this kit could feel like it’s “close enough” rather than perfectly aligned.
Quick check before you buy (mini FAQ)
Does it include rivet nuts for all sizes?
Yes, the listing states 70 rivet nuts total, split as 10 pieces each for M3, M4, M5, M6, M8, M10 and M12.
Is it only for sheet metal?
The description mentions fastening and riveting of sheet metal and pipe, plus related manufacturing uses. It also calls out examples like body panels and bicycle attachments.
How many mandrels come with the tool?
You get 7 interchangeable mandrels, intended to match the sizes covered in the rivet nut set.
What’s the main limitation of a hand rivet nut tool?
Because it’s manual, it’s best viewed as a practical workshop tool rather than a high-speed production solution for long, continuous runs.
Is the tool well suited to storage?
The kit is packaged in a carrying bag/case, with accessories packed close to their position to prevent movement and scratches—useful if you transport it around or keep a tidy bench.
