You´ve certainly already got in touch with screws whose head enables to use slotted and also Phillips cross type screwdriver. It´s quite handy as you´ll probably never be in a situation when you won´t have a usable screwdriver for a given screw by your hands.
But do you know that there is a special and the most suitable screwdriver for such screws, so called. SL/PZ (or SL/PH) , also called as „PlusMinus“? It is a screwdriver with this type of blade:
The praxis proves that such „hybrid“ screwdriver has the highest resistance against slip off, already at a minimal pressure on a screw. That´s especially beneficial for work on devices on DIN rail, as we don´t have to push on the screw (and thus a DIN rail, plastic older or a plastic enclosure) using uselessly excessive force.
Directly in our offer, you can find 6 types of screwdrivers with the „PlusMinus“ blade from Wiha:
Bit Stubby 41230 – extra short hand for a system of interchangeable Wiha SlimFix electric bits series, in a set with three bits - SL3.5, PH2, and SL/PZ2. An ideal helper even for very tiny places, VDE 1000V
