Hex head nuts and bolts — what is the earliest date of manufacture?
When were hexagonal head nuts and bolts first used, in lieu of square head?
In antiquity, the screw was first used as part of the screw pump of Sennacherib, King of Assyria, for the water systems at the Hanging Gardens of Babylon and Nineveh in the 7th century BC.[3]
The screw was later described by the Greek mathematician Archytas of Tarentum (428 – 350 BC). By the 1st century BC, wooden screws were commonly used throughout the Mediterranean world in devices such as oil and wine presses. Metal screws used as fasteners did not appear in Europe until the 1400s.
The metal screw did not become a common woodworking fastener until machine tools for mass production were developed at the end of the eighteenth century. In 1770, English instrument maker, Jesse Ramsden (1735-1800) invented the first satisfactory screw-cutting lathe. The British engineer Henry Maudslay (1771-1831) patented a screw-cutting lathe in 1797; a similar device was patented by David Wilkinson in the United States in 1798.
In 1908, square-drive screws were invented by Canadian P. L. Robertson, becoming a North American standard. In the early 1930s, the Phillips head screw was invented by Henry F. Phillips.
Standardization of screw thread forms accelerated during WWII so that interchangeable parts could be produced by any of the Allied countries.
Prior to the mid nineteenth century, cotter pins or pin bolts, and “clinch bolts” (now called rivets), were used in ship building.
In 1744, the flat-bladed bit for the carpenter’s brace was invented, the precursor to the first simple screwdriver. Handheld screwdrivers first appeared after 1800.
this website claims that the production of screws and bolts haven’t any significance. this means that the history is the same…….hope this helps
