I really like that they go in with a 4mm hex wrench or hex driver bit (look online for those, McMasterCarr has them).
They glide right in, even in hard maple and walnut, and even with using a hex wrench or hex bit in a hand driver, it's very easy to keep them straight.
They're durable enough for most applications, and about 1/4 cheaper than the brass inserts, which I did have a bit of trouble with in the harder woods, even with using an oversized hole and using a bit of paraffin wax on the threads. The recommended hole for these is 15/64", but a 1/4" hole works just as good and is a more commonly available drill bit size; most people will have a 1/4" bit on hand, not so much with a 15/64".
Like I said, I've used these in all types of woods ranging from poplar to hard maple. I have no idea why E-Z LOK markets these as being for soft woods; they work great in hard wood as well. So if you're trying to decide between these and the brass variety, give these a try, they work great, are easier to install than the brass ones and are way cheaper.
I've been using these inserts in a lot of different woods and the 15/64" hole works for every wood I've tried. One exception is purpleheart (a VERY hard and dense wood). The inserts go in with the 15/64" hole, but a 1/4" hole works a lot better; they glide right in. I couldn't get the brass inserts to go in purpleheart at all. These are great inserts and I'm glad I made the switch.
---NOT made in USA--- made in China with weak second-rate metal. Brittle teeth fracture and snap....and teeth are dull so they also hog out the hole destroying the entry location ---NOT made in USA---
FRAUD WARNING----> the Seller bad mouths anyone (all users + me) who expose the knockoffs and then overwhelms the Feedback with "Glowing Comments" to skew the Feedback average. See other ThreadLok "Current" comments from people who talk about how cheap they are.
These inserts are inserted into your pre-drilled hole with an Allen wrench/hex key. They are easy to use and very sturdy. I put them in with a little glue so they can't turn back out. The machine threading inside is well cut, the screws go in with out any trouble from burrs. And you can't beat this deal!
These are exactly 1/2inch tall, and almost half of that is the hex drive on the top. Use a 1.25" long screw for 3/4" MDF.
First, they were very cost/effective-my local hardware store wanted 3 to 5 times more per piece than the online price.
Second, with a properly pre drilled hole, they easily and securely went into the edges of the plywood using a hex head wrench.
Third, I used a 23/64" brad point drill bit to pre drill the hole into the edge of the 3/4" plywood, centering the hole in the plywood with a dowel jig fitted with a 3/8" collar. Not too much slop between drill bit and dowel collar.
Fourth, I threaded 1/4-20 stainless steel machine screws 1 inch long into these to do the fastening. I disagree with the reviewer that stated that 1-1/4" length fasteners have to be used. I counterbored the head of the machine screw into the plywood to get more length of engagement between machine screw and insert.
An excellent product!
Some notes on my order and other reviews here:
Binding: I used about 8 inserts at time of this writing and did run into the odd ball that would bind the screw as others noted. A 1/4-20 tape will cleared it but since I have a stock pile I just used another. Placed that one in a backup bag to tap out later when I run out of good ones. At the price, unless half the bag is bad I'm not too bothered. We will see.
9mm hole: A proper equivalent would be a 11/32 (8.7313mm) or even 23/64in (9.1281mm) bit. Another reviewer mentioned 5/16". I started with that but not very happy with that fit. Too tight and pushes the wood edge high. Get a 9mm or equivalent. 5/16" works but depending on the material and wood it will not be pretty.
Hope that helps.

These installed OK, but quite frankly they pulled out of the wood too easily. The included instructions describe the drill bit size (6mm = 15/64"). Read morePublished 26 days ago by Craig Markwardt

Oh, you think this might work in 23/32ths plywood or even 3/4 stock. You'd be wrong. I'll never have to buy these again.
3 stars for minimal tear out & thread finish.
