Fasten timber components securely with the Spax chipboard screw 4 x 80 mm. The 37 mm partial thread draws wooden boards firmly against each other to eliminate gaps and ensure tight joints. Thanks to the t-star plus T20 drive fit, you experience maximum torque transfer and stable screw driving without frustrating cam-out. The countersunk multi-head countersinks smoothly into the surface for a clean, flush finish without pre-drilling in softwoods. Protected by a corrosion-resistant Wirox coating, these durable steel screws provide long-lasting holding power for furniture assembly and indoor woodwork.
