Proftec chipboard screw. vz pk +intersection tx-20 (+bit) 4.0x60

Special features:PROFTEC chipboard screws, galvanised with a countersunk head and TX drive, are of professional quality for craftsmen who demand 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 work with.And thanks to the extra sharp screw tip, they grip directly into the wood.The tip of the PROFTEC screw also features a pre-drilling 'cutting tip', which in most cases allows you to work without pre-drilling and 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 screw sizes.Sharp milling ribs under the head ensure a neat finish when countersinking 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 function in wood-on-wood connections.Due to the 'free' shaft section of the PROFTEC screw, the second piece of wood is pulled extra tightly against the first piece, making the wood connection much stronger.The screws are packaged in a handy plastic bucket, as a bulk package.The recycled plastic bucket is convenient to use and has a handle for carrying, which saves a lot of cardboard waste if you are going to use larger quantities of screws.There are also 2 bits included in the bucket.Technical data:Diameter {mm}: 4Length {mm}: 60Thread length {mm}: 36Thread type: Partial threadHead type: Flat headDrive: TX-20Drive type: TXDrive size: 20Milling ribs: ExternalDrill point type: Cutting point type-17Head diameter {mm}: 7.5Material: SteelSurface treatment: Electrolytically galvanisedSurface treatment colour: BlueLubricant: GleitmoCE Standard: 14592Quality mark: SHRDiameter plug: 5|6
