Installing European Cabinets? Connect them the Right Way! The standard design for European Cabinetry is to have 2 rows of 5mm holes, 32mm apart on each side panel. This 32mm system allows easy customization of the cabinet. Shelf pins, drawer runners and other accessories are based on this pattern. Connecting these boxes together is easy when you use these 5mm connecting screws. Simply drill out the corresponding 5mm holes and insert the female shouldered part through the hole and connect by tightening the male part, exactly aligning the cabinets. The low profile truss heads almost disappear. The shoulder of the female part measures 1-3/8”which is ideal for connecting two ¾” panels. For different panel thicknesses, choose the proper length male screw from below. Metric M4x0.7 threads. Male screws may also be used for metric drawer pulls. Clear Zinc Plated. Uses #2 Pozi drive bit or slot. Made in Taiwan.
