Wood screw / board screw partial thread Velox 4.5x70mm SIT socket. Quantity per package: 200 pieces. 94570VLOXSP

Application and Benefits

The screw with dimensions 4.5 × 70 mm featuring a partial thread and SIT socket is ideal wherever quick and secure joining of wooden elements is required – from door and window frames, through furniture fittings, to chair structures and other furniture. Thanks to the patented SIT recess, the screw is centered on the first turn, eliminating the risk of spinning and ensuring stable holding.

• Fast installation – the partial thread and conical recess allow for rapid driving without the need for pre-drilling.
• Lower torque – the sliding coating and optimized thread shape reduce the force required for driving, extending the battery life in cordless screwdrivers.
• Wood protection – the patented thread area reduces fiber splitting, resulting in stronger and more aesthetic joints.
• Universal bit size – one SIT bit fits four screw diameters, simplifying the installer's tool set.
• ETA approval – the product meets the requirements of timber construction standards (ETA‑12/0198), ensuring quality for both professionals and DIY enthusiasts.

Construction and Installation Features

Made of blue galvanized steel, the screw is corrosion-resistant even in the humid conditions typical of carpentry work. The head is equipped with external milling ribs (for diameters Ø3.5 and Ø6) or internal milling pockets (for Ø4‑5), ensuring uniform fastening and minimizing the amount of debris on the surface.

• The conical SIT recess guarantees precise fit to the material and prevents deformation during installation.
• The partial thread enables quick "gripping" of the material after just a few turns, speeding up work on large batches.
• The galvanized coating protects against rust, extending shelf life even during long-term storage.
• Packaging of 200 pieces provides a convenient supply for larger projects without the need for frequent replenishment.

Thanks to these properties, the VELOX SIT/TX 4.5 × 70 mm screw is a practical choice for both installers valuing work efficiency and end-users expecting durable and aesthetic joints in their furniture or building joinery elements.
