With Spax chipboard screws, you can reliably mount furniture, hinges, and thin wood panels. The t-star plus T20 drive ensures an optimal bit fit, preventing cam-out and transferring torque directly into the screw. Thanks to the 13 mm full thread on this 4 x 16 mm screw, you achieve maximum pull-out resistance in sheet materials and hardware fittings. The countersunk head sinks cleanly and flush into the timber surface without splitting. Additionally, the chrome-free Wirox coating provides high corrosion protection for interior applications. With this pack of 1000 pieces, you complete any interior fitting task with speed and precision.
