The most common types of screwdriver are flathead (also known as slotted), phillips, and torx.
What to look for when purchasing your first set of screwdriver
Filling a garage or garden shed with your first set of hand tools? You can save money and storage by buying the right tools for the first time.
If you are just using your tools in a standard DIY, there is no need to invest expensive screws designed by electricians. But it does help to have one or two screwdrivers installed inside your home when you plan to work on electrical appliances or batteries.
Check out the screwdriver sets that come with ergonomic grips on the tools, and include a wide range of head sizes, head types and shaft lengths. In this way, one set can cover a range of common applications. Torx screwdrivers on sale at Sydney Tools is the best options.
Flat Head Screwdriver
It is one of the oldest types of screwdriver. It was invented in the 15th century in Europe and is one of the most common types of screwdrivers. As the name suggests it has a flat-shaped shaft tip with a single slot that operates with a borrowed screw head only. It can be manipulated or manipulated, but it is rarely struck because the sharp head has an ‘exit’ effect. Now what does that mean? Well ‘cam-out effect’ is a process in which a screwdriver usually slides from the top of the screw head, where the torque applied over the screw exceeds a certain limit or sometimes due to lack of space, which often causes damage to the screw head or screwdriver tip.
As the modern world goes from manual to manual or motor drive, these were the first steps toward moving screwdrivers to save time and get things done more accurately and precisely. These were invented in the 19th century by Henry Phillips with the aim of introducing power-driven screws in many industries. If you see these screwdrivers in the front, the tip looks like a reverse mark. These types of screwdrivers also show cam-out performance but are intentional when the torque exceeds the limit while tightening the screw-resistant screwdriver profile and extending the life of the tool.
The pozidriv screwdriver, unlike the Phillips screwdriver, has two cross-sectional markings based on 45 degree angles. These are designed and widely used in Europe. This mode does not completely overcome the cam-out effect but provides better resistance and smoother and provides more stability than Phillip’s profile, so it is used in applications that require high torque to tighten the screw.
Robertson or Square Screwdriver
A square screwdriver also known as a Robertson screwdriver, named after a Canadian founder.
The interlocking of the thicker of the square with the protrusion of the square, without the angle involved, ignores the effect of the cam-out, thus enhancing the focus. The small Taper shape on the front of the tool provides a good screw lock and thus makes it more comfortable to use. These types of screwdrivers were first used industrially by the ford car company, because these drivers accelerate production, reduce damage, and are highly reliable.
