Review: Great find! - An exceptional value great inserts. This was a project of replacing wear out old threaded inserts. I’m attaching photos to show the new inserts side by side with the old replaced ones. There are various tools to complete this job. You can use an M8 Allen Key That fits perfectly at the top of the insert but use extreme cautious screwing into hard wood especially if it’s for installing inserts for the first time. If using the correct size drill for the pilot holes you’ll have no problem installing the inserts with just an Allen Key. The best way to assure the inserts will not break during the installations is to use a long screw with two locking nuts on top of the insert and using a wrench to fasten them into the hard wood – see attached photos. Overall, it is a great value and an excellent choice for completing any DIY projects. It was easy to find the best fit thanks to the detailed specs provided by the vendors, easier then going to the big box stores. For an extra assurance I picked the Flanged ones for added strength at the top Hex area. Please note that these inserts are mainly for soft wood projects, but can be used on hard wood with a proper installation.
Review: Very easy to use and effective - I used these for two projects so far. I wanted to add castors to a workbench, to raise it and make it mobile at the same time. I took a couple of pieces of 2x4 cut to the width of the bench and inserted 16 of these, 4 per caster. I was then able to screw the 2x4s to the bench and then bolt the casters to the bottom of the bench. Very secure. The second application was securing a mailbox. I wanted blind fasteners but I didn't want to have to rely on wood screws. I cut a piece of 1/2" plywood to fill the gap under the mailbox I chose and drilled it to match the mounting points and added inserts. I screwed the plywood onto my mailbox post and could then bolt on the mailbox. it is so much easier to use the bolts than to try to start screws while reaching to the back of the mailbox. And the mailbox is much more secure. The flanged bolts I used won't pull through.

My wife is a librarian who has kids and teachers breaking furniture in the library. These have allowed me to repair several pieces with a stronger mounting point for legs and such.
