Ratcheting screwdrivers are a type of combination screwdrivers with replaceable bits, equipped with a ratchet mechanism that makes it easier to work in hard-to-reach places. They can be used in a wide variety of applications, e.g. for the assembly and disassembly of screws and bolts with different types of drives, such as flat, Phillips and Torx.
Ratchet Screwdriver Design
Ratchet screwdrivers, like all screwdrivers are composed of a handle and a blade. However, in these screwdrivers, the main blade or handle ends in a 1/4" socket handle and is connected to a 2-way ratchet mechanism. This mechanism makes the screwdriver operate like a ratchet wrench. Ratcheting screwdrivers with replaceable bits are equipped with handles that hold the replaceable bits. On the other hand, ratchet screwdrivers with replaceable double-ended blades are used to store the blades in their packaging. Screwdrivers with an offset handle are a separate group of ratchet screwdrivers, making it possible to apply greater torque by hand.
Ratchet screwdriver types
A distinction is made between ratchet screwdrivers with replaceable bits and screw heads on the basis of the replaceable accessories. A distinction is made on the basis of the handle shape between screwdrivers with axial or "T" handles.
Main technical data of the ratchet screwdrivers
The technical parameters that characterize ratchet screwdrivers are: overall length, blade length, handle length, handle type, type and size of replaceable bits or blades, overall weight.
Applications for ratchet screwdrivers
These tools are used for the assembly and disassembly of threaded fasteners (screws and bolts). These screwdrivers are therefore used in practically all industries. They are manufactured by Bahco, Felo, Gedore, Hazet, Stanley, Wera, Wiha and many others.
