Who invented the slotted screwdriver
This is a note on the screw and screwdriver. The big innovation in screw production came in 1770 when Jesse Ramsden invented the screw cutting lathe. This allowed for mass production of screws with precise sizes. The first screw and screwdriver were slotted screwdrivers and changed the world forever.
The first screwdriver was invented in the 15th century and was used to tighten or loosen screws. The screwdriver has come a long way since then, with many different types and sizes now available. The screwdriver is an essential tool for many DIY and repair projects.
How did Phillips screwdriver get its name?

What is the history of the Phillips head screw?
The Phillips screw was invented by Henry Phillips in 1935. It is a modification of the Thompson design, customized for production lines where screw guns were becoming increasingly common. The patent for the Phillips screw expired in 1966.
Did you know that the head of Phillips screws is designed to cam out whenever excessive force is applied? This specific design allows the screw to handle greater torque much better than other fasteners.
Who invented the ratchet screwdriver
In the early 20th century, a German inventor named Conrad Baumann invented a ratcheting screwdriver, branded Baumann-Weltrecord, with a fold-out handle to provide extra torque. This invention made it much easier for people to use screwdrivers, and the ratcheting feature was particularly useful for repetitive tasks. The Baumann-Weltrecord screwdriver soon became popular all over the world, and it is still in production today.
Algot T Johnson was the inventor of the 4 in ONE as we know it today. The 4 in ONE was originally patented in 1961 by Johnson. Johnson was born in Sweden in 1880 and immigrated to the United States in 1905. He died in 1971.
When did they stop using flat head screws?

What is the Canadian screwdriver called
The Robertson screwdriver is a type of screwdriver that has a square-shaped head, which allows for more torque to be applied to the screw. It is also known for its unique cam-out prevention feature, which helps to prevent the screw from slipping out of the head.
The sonic screwdriver is a tool that uses sound waves to levitate objects. It was created by a group of researchers from the University of Bristol in 2016. The sonic screwdriver is fitted with acoustic arrays inside an actual screwdriver.
What is a non Phillips screwdriver called?
The Frearson screwdriver is similar to a Phillips but with a cross shape. Frearson bits accommodate all Frearson screws, regardless of size. The Frearson head is tapered to a sharp point, which allows for higher applied torque than the rounded-tip Phillips.
One of the main differences between a Phillips and a Pozidriv screwdriver is the tip. A Phillips screwdriver has a pointed tip, while a Pozidriv screwdriver has a blunt tip. Additionally, the flanks on a Phillips screwdriver are slightly tapered, while the flanks on a Pozidriv screwdriver are parallel. Finally, Pozidriv screwdrivers have additional smaller ribs at 45° to the main slots, while Phillips screwdrivers do not.
What is the difference between a screwdriver and a Phillips screwdriver
Phillips vs Posidrive Screws
The Phillips screw head has four cross points and the posidrive screw head has a star with eight points. These two types of screws are different from each other in that the Phillips screw is designed to cam out under high torque, while the posidrive screw is not. This cam-out feature of the Phillips screw head can be an advantage in some situations, such as when driving screws into hardwoods. However, it can also be a disadvantage, as the screw can strip out the cross points if too much torque is applied. The Posidrive screw, on the other hand, is designed to resist cam-out and will not strip out under high torque. This makes it the preferred choice for driving screws into softwoods or when using power tools.
Tri-point screwdrivers are tools that resemble Phillips screwdrivers but have three points instead of four. These screwdrivers are often used with electronic hardware because they are able to fit into the triangle-shaped recesses at the head of the screws. The sides of the triangle bit are straight, which helps to avoid damaging the hardware.
