What is the purpose of square nuts?
A square nut, or square head nut, is a four-sided nut that is designed for use with a square head bolt and flat washer. Square nuts offer greater surface contact with the part being fastened compared to a standard hex nut, and therefore provide greater resistance to loosening.
What size is a M2 nut?

How is nut size measured?
The measurement of an inch nut or bolt will be listed as the thread size — a number between one and 12 or an inch increment followed by the threads per inch (TPI). If the diameter is less than 1/4 inch, the diameter will be listed as a number between zero and 12; the larger the number, the closer it is to 1/4 inch.
What are the dimensions of a 1/2 nut?

How are nut sizes measured?
To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.
Why don’t we use square nuts?
Material Efficiency In order to maintain the minimum amount of material between the threads and the edge of the nut, square nuts have a fair amount of ‘wasted’ volume in the corners that increases the amount of metal per nut for a given screw size.
Why did they stop making square nuts?
Square steel nuts were common on machinery of the late 19th through mid 20th century. Today hex nuts have displaced them. One reason is that a hex nut offers a new wrenching access at every 60°, whereas a square nut offers one only at every 90°.
Is M2 2mm?
M2 screws are typically used in the manufacture of small items of electrical equipment, laptops, cameras and mobile phones. The “M” designation for metric screws indicates the outer diameter of the screw in millimetres, so for an M2 screw, the outer diameter is 2mm.
What does M2 size mean?
The area equal to a square that is 1 meter on each side. Used for measuring areas of rooms, houses, blocks of land, etc. The symbol is m2. Example: A typical car parking space is about 12 square meters.

What year did they stop making square nuts?
For both bolts and nuts, heat treating/hardening of the metal was the last step. By the way…that 1949 agreement to standardize nuts and bolts into ISO inch and ISO metric was probably when the square headed bolts/nuts ended production in mass…as it would have required new investments in machinery.
When did nuts change from square to hexagon?
NUTS & BOLTS
The hex head was developed as far back as the very early 1830’s (James Nasmith) , and the square continued mainly in the production of agricultural implements. In Australia the implement manufacturers bought square mild steel bars and made their own, say into the 30’s (Depression).
When did nuts go from square to hex?
When were square nuts last used?
