Countersunk screw with groove DIN 963 M4x16 plastic

Product detailed description

The DIN 963 countersunk head screw with a continuous groove is made of plastic and is intended for applications where low weight and corrosion resistance are required. This screw has a metric thread with a diameter of M4 and a length of 16 mm, with a thread pitch of 0.70 mm. The screw head is countersunk, which allows it to be flush with the surface of the material into which it is installed, thus achieving an aesthetic and functional appearance.

The screw material is polyamide (PA), which is known for its good mechanical properties, such as resistance to impact and chemicals, while also providing electrical insulation. The screw has no surface treatment, which is common with plastic components, as the material itself provides sufficient protection against external influences.

The transverse groove on the screw head allows for easy assembly and disassembly using a standard screwdriver. The head diameter (dk) is 7.5 mm, the groove width (s) is 1 mm and the head height (k) is 2.2 mm. The screw is suitable for use in applications where low weight and corrosion resistance are important, such as electronic devices, plastic structures or other non-metallic materials. The screw meets the ISO 2009 and ČSN 021151 standards, which guarantees its compatibility and reliability in international applications.
