With the Spax chipboard screw 4 x 17 mm, you can securely mount furniture fittings, hinges, and drawer runners to thin sheet materials like chipboard, MDF, or plywood. The full thread design delivers strong pull-out resistance, while the countersunk multi head sinks cleanly flush into the timber without splitting the surface. Thanks to the Pozidriv PZ2 drive, you maintain optimum bit engagement and eliminate cam-out during fastening. In addition, the durable Wirox coating provides high corrosion protection for all your interior woodworking and cabinetry tasks.
