An assortment of zinc and bronze connector screws and trim caps from Hillman. Connector screws have a large shoulder under the head that locks the screw into the wood and prevents pulling through into softer materials. They act like a steel dowel forming a strong, stiff butt joint. A slight unthreaded portion at the tip makes it easy to line up holes during assembly. To install, simply align the two pieces and drill a pilot hole with a specially-designed, 3-step bit. Hillman's connecting screws can be removed and reinstalled several times without loss of holding power. Contents have Phillips heads. Full assortments of #57203 contain connector screws in 3/16" and 7/32" drill size varieties in 40mm, 50mm, and 70mm lengths. Full assortments contain fifteen (15) refills comprised of Hillman Item #'s 57204-57218.
