The Woodpeckers Multi-Knob can be used with a nut for use on an existing stud or with a bolt for use in an existing threaded hole. Available in 3 sizes for 1/4, 3/8 or 5/16 inch bolts and nuts. Just insert a standard hex nut or bolt into the top of the knob depending on your application. Unique design prevents the fastener from falling out but can be changed with a quick tap. Choose from four or twelve piece packs.
