In 1770, the English maker Jesse Ramsden (1735-1800) discovered the first cutting lathe was satisfactory. Ramsden was inspired by other inventors. In 1797, England, Henry Maudslay (1771-1831) created a large cutting screw lathe that allowed for massively accurate screw sizes.

In 1908, a square-drive screw was discovered by Canadian PL Robertson. Twenty-eight years before Henry Phillips Phillips patented his head screw, which was also a square-drive screw. The Robertson screw was considered a “first-drive break type of practical binder for production use.” this design became a standard in North America, which was published in the sixth edition of the Metric and Inch Standard Industrial Institute of Fasteners. The square drive of the head on the screw can be better than the head slot because the screwdriver will not escape the head of the screw during installation. The car model T made by Ford Motor Company (one of Robertson’s first customers) was used more than seven hundred Robertson screws.
In the early 1930s, Phillips head screws were created by c Phillips. car manufacturers are currently using car assembly lines. They need screws that can take up more torque and can provide tight fastenings. The Phillips screw head is compatible with the automatic screwdriver used according to the assembly.
Unfortunately, there is a screw company named Philips that never made any of it screwdrivers and screws. The owner, Henry Philips passed away at 68 years old.
