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)

Used one worked very well. Worked in tight space.

It allows me to get in areas not available with the big setting tool.

The tool and included rivnuts are all good, and great value for the price. One word of caution is that it'll be too long if you're using it inside shallow locations, for example inside of a 1" square tube. The tool bottoms out long before it can get the nutsert into place in those situations. I was able to get around this by stacking a bunch of washers between the hex nut bearing and the allen head, but seems like it'll be a common problem so I wish they would have included a few spacers to be used in shallow locations.I installed using an electric drill, slowly, with the clutch set low enough to keep it from overtightening. It was very easy to feel when the right right stopping point was.The plastic box is complete junk and doesn't give you any long-term organization. I would have gladly paid a little more for a nicer box with dividers for everything.

Below are tips I have learned from using this tool. Related to smaller size M4 and below.Installation process:1. Grip the large nut with a wrench. Hold the wrench to prevent the large nut from rotating. The large nut has a bearing inside to prevent the rivnut from rotating during the tightening process.2. Thread the rivnut onto the bolt. Get it finger tight. Finger tight will be the starting point for step #3.3. Use an allen wrench (or equivalent tool) to tighten the bolt 2.0-2.5 full turns (720-900 degrees).4. Done.Exceeding 2.5 turns will result in:- Bolt breaking- Head stripping- Warped threads from too much upward pressure inside the rivnut.Recommended add-ons:- Extra strong socket head bolts. McMaster item 91290A176 has grade 12.9 steel. Treat the M4 bolts as a consumable item. Need to replace an M4 bolt every 5-10 rivnuts. One can pull the old bolt out of the large nut's bearing fairly easily.- Wiha 71397 hex bit set has excellent tolerances to prevent cam-out. Make sure to have a socket wrench that fits the Wiha bits. The socket wrench will provide enough leverage when tightening the 2.0 - 2.5 turns. Additional info:- I wanted to find an M4 bolt with a hex head (instead of a socket head). A hex head bolt (tightened with a regular socket head driver) could handle the torque much better than a tiny hex insert bit. Unfortunately I couldn't find an M4 hex head bolt with high strength steel.- Do NOT use an impact driver on smaller M4 sizes! Need to hand tighten M4 sizes. I broke so many M4 bolts with an impact driver.- Other reviewers have pictures of broken bolts. This was from tightening past 2.0-2.5 turns.- Using the steps above will work with stainless steel rivnuts. Don't need to get brass, although I'm sure brass is a little more forgiving.- Overall, I am impressed with the tool. The stepper drill bit included in the box was a big help also.

I've used a few sizes now and these little tools actually work great. No giant, clunky, hard to use plier type too to have to lug around. They also easily stay in alignment, which is harder to do with plier type tools. Also, if the threads get worn or stripped in the future, I can simply grab another bolt of the right thread size and use it. Another great feature is that there is a bearing on the inside, which should help it last a long time.

Cons: Storage case is low quality and the step drill bit only lasted for one hole in 1/16 mild steel. All the rivnuts come in non-resealable bags.Pros: The setting tools seem to be decent quality and I have used several of them with no issues.Would recommend.

Worked great with the stainless rivnuts I got

This tool works pretty well for both jack and rivet nuts. (originally submitted Dec 2021 as 5 star, Updated and dropped one star in Jun 2023)The positive: I can insert nuts in tighter spaces that I can with a standard lever based tool. One of the biggest advantages is that one can buy different length bolts at many hardware stores. This makes it possible to use with the various lengths of jack nuts that are available. And you can replace the bolts cheaply if they get fouled up. I have stripped some bolts using stainless rivet nuts.The negative: After a few dozen 6 mm stainless jack nuts were set I found that the surface of the tool would not hold the jack nut from turning. So I couldn't set the jack nut. The conical center isn't big enough and apparently the surface got slicker. I finally put some fine sand on the surface of the jack nut and that helped some. But it took multiple attempts to get the nut fully set. I tried a rivet nut and still seem to work ok. But I needed jack nuts for the soft aluminum plate I was working with.I have since noticed one other brands has a scored surface on the bottom of the bearing tool. I would expect that to work better.

Muy práctico y de buena calidad por el precio

Simple tool to use, works great , easy instructions.I installed an e-bike conversion kit. Needed to install rivet nuts on the down tube to make for a solid battery mount.This kit did the job. Used an right angle drill attachment on my drill to drill the holes .

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

Cumple con lo que yo solocite

Cant say anything bad about this set. I have actually only used one size for a project that required a small tool to install. It worked great. Cant see why they all wont do the same.
