With Spax 4 x 50 mm chipboard screws, you assemble timber frames, furniture, and panels like mdf or chipboard with speed and precision. The partial thread design pulls wooden components tightly together, eliminating gaps for a solid joint. Equipped with a t-star plus T20 drive, each screw delivers exceptional bit grip without cam-out, allowing smooth driving with maximum torque transfer. The countersunk multikop head sinks flush into the wood surface without splintering, leaving a neat and clean finish. Featuring an innovative wirox coating, these steel screws provide durable resistance against corrosion. With a box of 500 pieces, you have the reliable fastening power needed for any interior finishing project.

Frequently asked questions about this product

Answered by specialists

Which screwdriver bit is required for these screws?: You need a T20 bit, preferably a Spax T-STAR plus T20 bit for optimal grip and maximum torque transfer.
What is the benefit of the partial thread design?: The partial thread pulls the top board tightly against the underlying structure as the smooth shank rotates freely in the top piece.
What are the dimensions of this screw and its thread?: The screw has a diameter of 4 mm, a total length of 50 mm, and a thread length of 32 mm.
What are the advantages of the WIROX coating?: The WIROX coating provides significantly higher corrosion resistance than conventional zinc plating and is free of chrome-VI.
Is pre-drilling required before driving these screws into wood?: In most softwoods and board materials, pre-drilling is not necessary thanks to the countersunk head and specialized screw tip.
