Product Description

E-Z LOK Hex Drive inserts for soft wood are an inexpensive insert for use in ready-to-assemble furniture, drawer pulls, or wherever the avoidance of thread stripping is desired. Ideal for use in materials such as pine, plywood, composition board, and MDF, Hex Drive inserts feature tapered external threads which resist pull out caused by vibration. These die-cast zinc inserts are available in a flush design for "below the surface" installation or in a flanged design for installation depth limiting applications.

These inserts work beautifully in all the woods I've tried so far, ranging from poplar to hard maple.
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.

4/18/12 UPDATE:
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.

I saw a dollhouse type bunk bed at a furniture store and decided I could build it for less than a grand! I found the plans and went to Lowe's to buy the lumber and hardware. The first screw inserts I bought were 20mm and too long to really use with 3/4" MDF, but more importantly they were $3.58 for a package of 4!! I bought them KNOWING I could go home and find them far cheaper on line. Fastenal has them too, but I decided to use the more familiar Amazon. They have a hex head for insertion and nice course threads that go nicely into a 3/8th hole (a common bit for most DIYers).

Excellent value.

These inserts are the best I've ever seen. They don't even compare to the cheap brass inserts that hardware stores normally sell.

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!

I bought these to complete a DIY server case, and they are perfect for 3/4" MDF.

Note:
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.

These inserts have added a new dimension to woodworking. No more using screws in particleboard. Now I can use bolts and not worry about going to a bigger screw everytime I take something appart.

When I need a few things I like to buy many so I have more in the future. No exception here. Shipping was SUPER fast.

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.

Good luck

the brass inserts tend to strip out. these zinc inserts with hex drive work much better. I epoxied them into end grain 2 X 4 to hold carriage bolts to act as levelers on a 350+ lbs workbench and they are rock solid. The bench is on casters so it is up and down for every move and the carriage bolts have not given way at all. well worth the coin.

I used these to secure a 3/4" plywood panel to a 3/4" plywood box, and they were perfect.
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!
