Ratings & Reviews for Hillman 1/4-in x 20 Steel Cast zinc Wood insert Nut 4 Count

Works fine if you use your head.

Yes, as others said, the 6mm drive on these will strip out pretty easily. However, there are other ways to set these inserts. When the first one went into the kiln dried Douglas fir, it stripped about half-way in. I didn't want to mangle it up trying to get it out, so plan B. I grabbed a two inch long 1/4-20 hex head bolt and a 1/4-20 nut. I installed the nut onto the bolt, then threaded the bolt into the insert. I then tightened the nut against the insert, used a 7/16 inch wrench on the bolt, a...

The person that makes these is not educated usable

It fits but it made wrong it will split the wood on insertion because of the wide ness at the top

Couldn't figure out how to uses them.

This worked for us

Product was ok..just what we were looking for

Do not use on hard wood

The first one went in no issues. The remaining three stripped and cause so much headache. The first one gave me hope that the second one was just faulty. I went up in drillbit sizes just in case and each time they stripped at about 80% in.

Threaded inserts

Easy installation

Soft metal won't withstand pressure

I had installed 16 inserts into a slab of wood (soft wood) and the opening for the hex key got stripped on 4 of them (thankfully they were about 95% of the way in) and 2 the side walls of the head split. I had to hand saw one out and was able to use the remainder of the insert but I these are not reliable enough to be able to use. Would recommend a sturdier / stronger metal insert through a competitor. The ones that installed correctly and didn't strip I was able to twist flat with the wood but ...

Threaded inserts

I am using these to make wine bottle stoppers on lathe they seem to be working great for this application.

Very poor quality

Very poor quality. I had to look up to see what size drill bit to use for these. The manufacturer says 5/16. I tried one out on a sample piece of wood. First one split out the head of the insert. You have to use a 6mm hex head Allen wrench to insert it. Drilled a true a straight hole. No Good. Second one I wallard out the hole. Seemed to work better. Went to the work piece. And the head split open again. Had to use pliers to remove the 3/4 of the way insert. They are tapered. So th...

Use a larger bit than you think for the pilots.

Pre drilled holes but every other one of these stripped out while inserting.

These are cheap metal.

the threads are bad, bolt will not go all the way down, had to use a tap to use it. Put a bolt all the way in and use the bolt to tighten into the hole. The hex key part will strip before you are done if you use that option. Cheap foreign metal. Not even as good as brass

Brittle

Very brittle, used one for a crib and the end crumbled into peices adding a whole days work. Do not buy your better of getting some rockler.com

Good for some scenarios.

It's easy to use but not easy to get enough glue into the hole that you are inserting it into. If you don't get enough in there, it will pull out if you apply to much force from a screw. Probably best used in a situation where you don't have to put a lot of tightening force on it.

Seems good on soft wood.

Broke on Hard Wood

easy to use

Worked well, as they were supposed to.
