These HIGHPOINT® Solid Brass Slotted Inserts are for ready-to-assemble furniture, drawer pulls and wherever you need an easy-to-install threaded insert. Large teeth give increased holding strength in particleboard and end-grain applications. Simply drill a pilot hole, and thread in the insert with a screwdriver or T wrench. Pilot-hole measurements may vary due to the nature and grain of wood. We recommend a trial installation on a piece of scrap.
