What Customers Are Saying

Most customers find these threaded inserts work well for creating reusable connections in soft woods, particle board, and plywood, praising smooth threads and reliable anchor points. However, many report the metal strips or breaks easily during installation in hardwoods like oak or cherry, with hex recesses failing under minimal torque. Some note inconsistent performance even within batches, and a few mention lack of clear installation guidance. Despite material durability concerns, most users who follow proper technique in compatible materials consider them effective and worthwhile for furniture assembly and hardware applications.

terrible inserts

Would Not Recommend

I tried to install 2 of these in 3/4" OSB and both failed by breaking at the hex opening. I'm returning the rest and ordering some hardened ones online. I should have read the reviews before I bought them.

Good for anchoring in a wood door frame.

Would Recommend

Got the job done on a door hinge mount where the wood screws had pulled out. These were inserted into the holes in the door frame and screws fastened snugly into them. Problem solved.

more than half split during insertion

Pre-drilled and dry-fit multiple inserts and half of them split between halfway to 3/4 of the way in. Pre-drilled a few to 11/16 and they still split during installation. Material was 1.5mm fiberglass and 1/2" marine grade plywood

Works Great!

Would Recommend

So glad we found these! We had a small table which had two legs that fell off due to the screw holes being wallered out. These were perfect by hammering them into the hole, then the screw fit perfectly. The table is like new again.

Good buy, but be careful installing

Would Recommend

Easy to use, very sturdy. But the hex point used to screw it in can easily crack and make it difficult to fully install. But overall a good product.
