🔩 E-Z LOK 903816-13 Threaded Insert, Zinc, Hex-Flanged, 3/8"-16 Internal Threads, 13mm Length (25-Pack) Review

For attaching an MDF panel to an 80/20 frame. Just drill a hole and twist them in place. They could break out if there was a large side load.

I installed them on the underside of the melamine backing on my drill press. They work exactly as advertised and give good strength to anything that can be bolted to them. I recommend them.

I don't think it's really intended for use with really hard woods like white oak. The metal broke trying to sink it into the wood, but works great when screwed into the wood.

This product is designed for softwood as described. However, this item can be used on hardwood if the hole is drilled to size and oil is applied to the threads to allow the threads to cut into the wood. Using the recommended bit size in hardwood will require too much torque and will destroy the flange. I destroyed four flanges before I found out. I would prefer the hex to go through the shank.
