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

These are well made inserts. The threads are sturdy and true to size. I installed them on the bottom of a cabinet and then installed casters. Now my cabinet is easy to move and I have not had any issue with the inserts holding. I recommend buying this set if these are the sizes you need. Since buying these, I have begun thinking about other projects I can use these for. I only wish I had these years ago, as I would have been able to save and repair other cabinets and pieces of furniture. These are super simple to use and work as advertised.

Nice selection of metric sizes

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

Nice assortment of sizes at a good price

Perfect variety for furniture repairs.

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.

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.

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.
