Screw-in inserts are by nature quite stiff to screw in @timothyleong. They won't just screw in with no resistance; they need to cut their own thread into the timber as they go. However, I can certainly understand your hesitancy given feedback on them. Perhaps you could try one in a non-critical location to get an idea of whether this will work. As a lubricant, you could use an oil or wax.

Hi guys,
I saw that video and I tried that method but without an impact driver. I currently have one insert that is broken and another for some reason the bolt is loose in the insert and wont come out. Im trying to find youtube videos to solve those problems but if you guys have any tips that would be appreciated.
Also one of the holes I drilled was too small, is there any way that I can drill a bigger hole over it?
Once again thanks for all your help!
Afternoon @timothyleong
You asked this on the previous page...
"Or do you recommend other inserts?"
Right at the very end of the YouTube video Ted provided above - the presenter made it very clear to buy steel inserts.
I used the aluminium ones mentioned earlier on the underside of a very old bar stool. I replaced the old wood with new plywood and used the inserts to anchor the four legged base. I managed this with an appropriate sized hole (using a drill press), allen key and WD-40. I treated the insert like a metal die, turning one revolution and backtracking half a revolution. Fractured one but in the end managed to insert four of them.
You mentioned above that one bolt (M6) is loose and won't come out - most likely that very soft aluminium thread has been stripped by the steel bolt.
When it came to attaching the back of the stool, I gave up on these aluminium inserts. I used large screws strategically sized and cut with an angle grinder. I just did not trust the holding power of these inserts should someone lean back heavily on the stool.
I would love to see the legs you're going with.
I would love to see the legs you're not going with.
And I would love to know why. 😀
You mentioned the table top is 25mm?
You don't want wood screws?
How are you going @timothyleong? Did you try a lubricant like WD40? If you continue to have issues placing the inserts, then it would be best to look at other solutions. Your timber might be too hard for these inserts. If you provide some details on the legs you've chosen, I'm sure our helpful members will be able to suggest some alternate fixing methods.

Hi guys, I managed to fit the inserts. Looks like this:
So I have 2 questions:
1) I still have one hole where I drilled too small. Can I use a step bit to enlarge the hole?
2) And also in the last picture there is a bit of a gap between the legs and the table. I think its because the inserts are not flushed enough into the table. It looks quite stable at the moment. Should I try to screw them into the table somemore?
Thanks again for all your help!
Hello @timothyleong
Thank you very much for posting photos of your adjustable table project. In regards to the smaller hole that you've drilled into the table, it is still possible to drill a bigger one. I suggest measuring how deep the hole is and marking the drill bit with a bit of tape so that you don't drill past the depth of the hole. Getting the next size up in your drill bit kit should be ok, but please remember to measure the item you are putting into the bigger hole.
In regards to the gap between the table, if the table is stable and there is no tipping in any of the corners, I propose leaving it alone. At this point, repeated disassembly and re-installation might not be good for your table's fixings.
If you need further assistance, please let us know.
