This is an excellent product for soft to medium density wood.
DO NOT use for Hardwoods. Use the stainless steel type. E-Z LOK Threaded Insert For Hard Wood; 1/4-20 Int Thread; 303 Stainless Steel (Pack of 10)
It is a well made product that works extremely well, however the heading states:
"E-Z LOK Threaded Insert For Hard Wood".
I could easily rate this a 5 star if it stated it was for soft to medium density woods.
Suggest the following;
26/64" (13/32") pilot drill in Hard Wood such as oak or maple.
25/64" pilot drill in Medium Density such as Poplar or Ash.
3/8" pilot drill in soft to medium density woods such as pine.

These were not only shipped quickly, but they were by far the best price for threaded inserts I found anywhere. There were some small manufacturing blemishes on the threads themselves where the beginning of the thread was bent up slightly and prevented threading. These, however were a small percentage and easily corrected just by running a flat head along the threads. It didn't take more than a couple seconds to correct these few and they all worked smashingly.
Thanks for the hardware!

Been using these for knockdown furniture projects. They go in easy with the insertion tool, and stay fast. I have yet to have one back out.

Great buy for the money
I got 2 bags of this insert for a project jig I was building and they work great. You have to make sure you start them stright or you will chip out the top of the start hole. Read more

Good Value
Quality brass inserts at half the price offered at Woodcraft or Rockler. And they are the same as I can tell.
