Spax MDF Screws

Spax MDF screws are designed to give you a clean flush seating for screw fixing MDF and particle boards. The countersink heads have cutting ribs to give a flush seating without splitting or raising the board around the screw head. With a deep thread and slim profile these gimlet pointed screws can be driven home without pre-drilling when using the thinner boards, the deep thread providing a firm strip resistant grip on the material. T star drive needs a T15 bit for 3.5mm and T20 for 4mm screws. Blue zinc plated.
