With Spax-M mdf screws, you can join fibreboard and mdf quickly, cleanly, and without splitting. Thanks to the special Cut point, you can drive screws directly into board materials without pre-drilling, even close to edges. The partial thread pulls wooden components tightly together without gaps, while the narrow countersunk head with milling ribs sinks neatly flush into the surface. The precise t-star plus T15 drive delivers optimal power transmission and prevents bit cam-out during screwdriving. Featuring a durable Wirox coating, these 3.5 x 50 mm steel screws provide reliable corrosion protection for furniture making and interior fitting projects.
