Countersunk self-tapping screw DIN 7982 C/ISO 7050, 5.5 x 22 mm, hardened and zinc-plated steel

In use, the countersunk self-tapping screw cuts its own thread in the sheet and pulls the countersunk head flush into the recess. The data also state a length of 22 mm. This version comes with a nominal diameter of 5.5 mm, a length of 22 mm, a head diameter of 10.8 mm and a head height of at most 3.4 mm. In addition the data give cross recess PH3.
