With this Spax chipboard screw, you achieve strong and reliable joints in timber and sheet materials like chipboard and mdf. The t-star plus T20 drive recess ensures a firm bit fit, preventing cam-outs and stripping so you can drive screws rapidly and with total control. Thanks to the full thread, you gain maximum pull-out resistance and superior load capacity, making it ideal for furniture building, interior fitting, and flush mounting hinges or hardware. The countersunk multi head sinks neatly flush into the surface without splitting the wood. In addition, the Wirox coating provides significantly better corrosion resistance than standard zinc plating for lasting results in dry indoor and covered outdoor projects.
