Countersunk screw with slot DIN 963 M3x20 plastic

Product detailed description

The countersunk screw with a slot according to DIN 963, ISO 2009 and ČSN 021151 is made of plastic, specifically polyamide (PA). This screw has a metric M3 thread with a length of 20 mm. The countersunk head allows the screw to be embedded in the material so that its head is flush with the surface, which is ideal for applications where it is necessary to achieve a smooth surface without protruding elements.

The screw head has a diameter of 5.6 mm and a height of 1.65 mm. The groove width is 0.8 mm, while the groove is continuous, which allows the use of a standard flat screwdriver for assembly and disassembly. The thread type is metric with a normal pitch of 0.50 mm, which is common for screws with this diameter.

The plastic material from which the screw is made provides advantages such as low weight, corrosion resistance and electrical insulation. These features are useful in applications where weight needs to be minimized or where the screw is exposed to moisture or chemicals. No surface treatment is applied, which is typical of plastic components that already inherently provide sufficient resistance to external influences.

This screw is suitable for use in various industries, including electrical engineering, where electrical insulation is important, or in applications where resistance to chemicals and moisture is required. Its design features allow for reliable and aesthetic fastening of components.
