The Pozidriv screw generate has eight Get hold of details entirely fashioned from two intersected crosses. It’s also exclusive from Phillips drives due to its 45-diploma radical indentations.
You’ll find TORX screws Employed in quite a few electronic equipment. They include a 6-position star form located in the middle of the screw head.
The large cam-out probable of slotted screws, the necessity for specific alignment to avoid slippage and damage to the motive force, fastener, and bordering surfaces, as well as the obstacle of driving click here with run instruments were being all concerns that the Phillips screw style and design was designed to handle directly.
