Chipboard Screw TX20 4.2x30mm Electrogalvanized 250pcs Fast 285130

Description

Fixed chipboard screw 4.2x30 mm is a professional wood and board screw specially developed for fast, precise and stable mounting of chipboard, MDF, plywood, OSB and other types of wood-based board material to wooden joists. The screw's sharp tip provides an immediate grip in the wood, which makes the installation both faster and more ergonomic without the board slipping or wandering at the start.

Under the countersunk head are integrated milling ribs (grooves) that effectively cut away the wood fibers when retracted. This means that the head automatically sinks smoothly and evenly into the surface layer of the board without cracking the material, raising fibers or leaving uneven edges - creating a perfectly flat surface ready for filling, wallpapering or painting.

Features & Benefits

• Self-countersinking head: Cutting grooves under the head mill out the material and provide a smooth, flat assembly ready for filling or surface coating.
• TX groove (Torx 20): Safe power transmission with minimal risk of slipping, even at high speeds.
• Optimized thread: Cuts quickly into the wooden stud and provides high tensile strength without unnecessary cracking.
• Electrogalvanized finish (FZB): Durable and proven surface treatment suitable for indoor use.
• Practical packaging: Supplied in a robust box of 250 pieces - perfect for renovation, flooring and carpentry projects.

• Fastening chipboard, floorboard, plywood, OSB and MDF to wooden joist substrates.
