With Spax 3.5 x 20 mm chipboard screws, you achieve strong and clean timber connections across wood, chipboard, and mdf. The t-star plus T20 drive ensures a secure bit fit to prevent cam-out and maximise power transfer during rapid fastening. Thanks to the countersunk multi-head, the steel screw sinks smoothly flush with the surface without splitting the material or requiring pre-drilling. Its full thread delivers high tensile strength to firmly hold furniture hardware and thin panels in place. Finished with the durable Wirox coating, this 200-piece pack provides superior indoor corrosion protection compared to standard zinc-plated screws.
