230 Pcs Threaded Inserts Nuts Assortment Tool Kit - 11 Sizes Metric M4/M5/M6/M8/M10 Hex Socket Drive Furniture Screw-in Wood Inserts Bolts Fastener

I had to get these because a product I purchased from another site was missing this and I received them super fast and was able to complete the assembly without having to wait weeks for them to send what I needed.

I just got into woodworking, and it requires a lot of jig construction. So you get to buy tools to make tools before you get to actually make stuff. These have been great where I need removable or adjustable pieces. I've used them in oak, maple, pine, and plywood. I would recommend adding CA glue to plywood, but in every case they grabbed great, and haven't required any tweaking or tightening after initial installation.

Used these in making a removable cheek riser on my Yugo M48. I used the m4 after drilling a pilot hole, one of the 2 cracked despite no real tension on screwing it in. I removed it and replaced it without issue. I did use a dab of wood glue on the "threads" of the insert just for reassurance. All in all they're fine for non critical / non heavy duty applications

If u are starting to buy threaded nut, just buy the set because it gives u the flexibility to use the different sizes.. what I mean is, I like to minimize clutter on a.project. in you project if you are able to use the smaller sizes then this set gives you the flexibility to do it

This product is awesome and really took my project to the next level I was able to make a custom amp rack for my car stereo project

The material breaks quite easily. The hex recess stripped relatively easily. So, don't use it for hard material or application where you need to remove/retighten nut. It is a cheap option and it does work fine for weaker wood material. I tried a couple M4 and M5, and they stripped easily. The good thing I can break them easily with plier to get them out.

This works as expected.

Nice collection of threads just what I needed. Good quality and seems hardy. I would recommend.
