Chipboard screw 5.0x50/30 torx Professional chipboard screw with special cutting head that prevents splitting of material. With high-end glide 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 craftsman. Due to the coarse thread, the screws turn in quickly. A transparent wax layer has been applied to the screw, making them very easy to turn in and process. And due to the extra sharp 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 in most cases without pre-drilling, 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. You therefore do not 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 executed in a partial thread variant, with a spiral on the shank; for optimal functioning in wood-to-wood connections. Due to the 'free' shoulder part on the PROFTEC screw, the second wood part is pulled extra tightly onto the first part, making the wood connection much stronger. The screws are packed in a handy plastic bucket, as bulk packaging. The bucket made of recycled plastic is handy to use and has a handle for lifting, which saves you a lot of cardboard waste if you are going to use larger numbers of screws. There are also 2 bits packed in the bucket.
