HIFESON Rivet Nut Tool Hand Nuts Riveter Rivnut Tool Metric and SAE with Step Drill Accessory for Stainless Steel Nuts M3 M4 M5 M6 M8 M10 10-24 1/4-20 5/16-18 3/8-16 (Stainless_Steel)

The smaller ones worked great. The larger ones are a little more challenging but worked.

Easy to use just pop in the previous hole and it will tighten, cuts your labor in half the time of more.

Well as other reviews have stated these things strip out very easily. I was attempting to rivet my stick steering bracket back to my boat gunwale (aluminum). Over the years the manufacturer pop rivet work itself loose and pulled out. I thought the bolt ins would be a simple solution. The smaller rivets will not pull down enough to hold anything before stripping out. I had to cut the the rivet out with my angle grinder because bolt would not back out. Looks good on the drawing board and videos but didn't work for my application.

Whoever invented rivnuts is a genius because this is exactly what I needed to install 3” caster wheels on bottom of steel frame baby lounger. I didn’t want to buy the big rivnut tool because in tight spaces, I won’t have room to use the tool and so I liked this tool because I could use a drill and can work in tight spaces. I’m sure if I was installing rivnuts a lot, I would get the tool. So this kit does the task. And I REALLY want to give it 5 stars but I had to knock off a star for two reasons: 1) the step drill only goes to 12mm despite the product description picture clearly showing 13mm which is needed for M10 and 3/8-16 size threads which as it turns out is what I need for those aforementioned 3” caster wheels. Thankfully I had a 1/2” drill bit (12.7mm, just shy of the required 13mm needed) that I was able to manipulate by angling the drilling (be careful!) and then using a hammer to pound the rivnut+mandrel in. Not exactly the most professional but it got the job done and you can’t see the non-perfect hole once the rivnut is installed. 2) I have FOUR, yes 4! different sets of ratchet sets, hex wrenches etc + a gazillion Allen wrench combinations and NONE of them was the right size for that big fat 3/8-16 mandrel. Thankfully I eventually found a correct size Allen wrench without having to make a trip to the store or waiting another day for Amazon delivery. Perhaps I don’t have ALL the size tools that others do, but since ALL my other tools fit EVERY other mandrel BUT the 3/8-16 one, maybe a heads up in the description/picture or better yet, use hex head for the bolt instead since that’s a more ubiquitous fitting that people have laying around if they are undertaking this task. So yah, I had to do it manually and my poor thumbs are sore. And no, I didn’t have random 3/8-16 bolts around that I could have substituted out. All in all though, this kit got the job done and I’m happy with it and will put this to good use in future.

Smaller sizes are ok…larger sizes didn’t work. The 3/8” bolt striped out on the second insert. Took an hour to extract the failed insert. To be clear, I believe the mild steel bolt failed. Mild steel Vs. stainless, mild looses every time! Purchased grade 8 bolts to replace all the mild steel bolts —- also, the drill sizes are METRIC while the bolt sizes are imperial. Confusing.

They’re WAAYY OVERDUE!! I have the big tool to attach it!! But this bypass the big tool!

No instructions but u can figure it out. Hold with a wrench and tighten with a hex key wrench. Do Not use stainless rivnuts as the metal is too hard. Use zinc rivnuts. Tighten but don’t crank on it especially for the smaller sizes. Update. The smaller M4 or smaller sizes strip out. I baby it and there just isn’t enough strength in the bolt to fully collapse the smaller rivnuts. Just stay M5 or larger.

Good tools.

Received goods as described, fast shipping and a well packed shipment

Fait bien le travail, facile a utilisé je le recommande pour bricoleur.

Lo uso en un proceso de instalación de cámaras de seguridad sobre paneles de fibra de vidrio, aunque falto una medida, no es la que estoy usando con frecuencia, estoy satisfecho con el producto

The product works but the smaller attachments can not handle the costsnt torque.

Usé la herramienta en forma manual para colocar unos remaches que necesitaba en mi auto. Funcionó perfectamente.
