Extremely high quality. The hex shape for inserting with a drill or driver is far superior to other designs (eg slot) by the competition. This is my go to for attaching table tops, desk tops etc.of specific designs. I router a slot on the other parts the solid wood top is attached to along with a bolt compression washer and standard washer to allow for wood movement.

Inserts worked perfectly. I drilled the holes and inserted them into ash to hold metal legs.
