Chipboard screw 5.0x70/42 torx Professional chipboard screw with special cutting head that prevents material from splitting. With high-end sliding coating and torx head. Packed per 200 pieces. Special features PROFTEC galvanized chipboard screws with flat countersunk head and TX drive are of professional quality for craftsmen who demand high standards from a good screw. The design of this screw was improved in 2023 and meets the highest quality requirements of the professional. Due to the coarse thread, the screws drive in quickly. A transparent wax layer has been applied to the screw, making them very easy to drive in and process. And due to the extra sharp and pointed screw tip, they grip directly into the wood. At the tip of the PROFTEC screw there is also a so-called pre-drilling 'cutting tip'; this allows you to work without pre-drilling in most cases, without splitting the wood. The 3.5 – 4.0 – 4.5 – 5.0mm screws can all be driven in with the same TX-20 bit. So you don't have to change bits when screwing with different sizes of screws. Sharp milling ribs under the head ensure a neat finish when you countersink the screw head into the wood. All screws from 40mm length are designed as partial thread variants, with a helix on the shank; for optimal functioning in wood-to-wood connections. Due to the 'free' shoulder part of the PROFTEC screw, the second piece of wood is pulled extra tight onto the first piece, making the wood connection much stronger. The screws are packed in a handy plastic bucket, as a bulk package. The bucket made of recycled plastic is convenient to use and has a handle for lifting, which saves a lot of cardboard waste if you are going to use larger quantities of screws. There are also 2 bits packed in the bucket.
