The glass knob has an imbedded threaded insert in the back, & comes with a 8-32 thread truss head screw which will allow for mounting the knob from the back. Enliven the furniture & cabinets in your home with this most delightful glass knob! Use only hand tools to install glass knobs on your cabinets. Power tools (or even wrenches) may cause damage to the thread or to the knobs. Insert bolt through head of knob. To tighten, hand turn only the nut on the back of the screw (this is one reason that the heads of the screws are smooth on top and do not have a slot.) Do not turn the knob itself as it may cause breakage. Tighten carefully but do not over-tighten – remember they are made of glass & are by their nature, fragile. We will not replace broken knobs due to over tightening or mishandling.
