Threaded Insert Nuts, 230 Pcs Zinc Alloy Furniture Hex Socket Drive Screws, Assorted Screw-in, M4/M5/M6/M8/M10 Flat Head Threaded Rivet Nuts Assortment Kit for Wood Furniture (230pcs)

A good selection in the box, I purchased to use in hardwood, and they went in with no problem

Good quality

A good selection of the common size of metric bolts used in furniture construction. Drill a suitable pilot hole and then screw in using hex wrench. Don't make the hole too tight as the zinc insert will shatter. Best inserted si that the tightening fixing pulls the threaded insert into the fixing material.

I just needed some to go in some mdf and some pine, as I have a table top that I diss/assemble every other weekend. Much better than repeatedly inserting and removing screws. The right size hole and soft material, I didn't have any issues with them, but maybe I would not try putting them in a hard wood.

did the job they always do reliable easy to use just a bit of common sense needed advice from he who knows always try out on scrap bit off wood till you get the right size drill bit you want the whole tight so you can screw the bit in and not worrying it will come out or loos easy do it right and it will be stiff to screw in just the job if you can just push it in it will not work and it will pull out

I would offer this 5 stars, however there is no information offered around the size of the pilot holes required for each insert. I had to do a lot of trial and error to figure out the correct pilot hole to prevent the wood splitting and the insert collapsing under strain.However I did find the correct pilot hole on the M6*15 to be 8mm exactly. I was able to tighten down bolts quite hard without pulling the insert out of the wood (this was on a refined chipboard table with laminate covering).Also don't forget to correctly countersink/bevel the edges of the hole so the head of the inset fits flush in the wood.

The metal at the top of the nut is incredibly cheap and thin. If you want the nut to sit flush with the wood you absolutely need to use a chamfer or bevel to widen the top of the drilled hole. If you don't do this, the top of the nut will sheer off. At that point, it will also be difficult to remove the nut as the Allen key slot will have widened as well making it impossible to remove.If you just need a quick and dirty job, these'll do. If you take pride in your work and want something that'll last, avoid these

Bought these so I can put some ancor points in my van to put the bed in an out when needed.Easy to screw down into the ply floor and nice and easy to add bolts into.
