What is a square nut?

The

square matrix is ​​a steel fastening device with four sides that destroys a steel screw. Made before a hexagon nut, a square nut uses a special -purpose key to tighten and release from its screw. The square matrix can be used from small applications of fasteners to very large, because the success of the design has proved to be worthy of innumerable uses. One of the reasons why the square matrix is ​​so successful is the ease of removal and installation, because the square design has proved to be resistant and practically immune to being rounded by the key. The first versions of the square nut were carved from wood and used on threaded wooden pegs. The square design made it easy to create the right key or tool to tighten the matrix to the site. As the technology began to replace the wooden fasteners for more durable and longer -term steel versions, the square nut was soon formed from the steel bar stock and adjusted to be used on steel screws and fastenersthe elements.

sharp corners of nuts were often devastating for wood or metal surrounding the connecting elements. For each nut, large flat steel pads were soon used to provide some protective material around the corners. It turned out that the pads not only protect the components from damage from the corners of the nuts, but also managed to spread the load of forces pushing on the matrix over a larger area, allowing greater strength. The nuts themselves were often forged with a flat side and a convex side. The flat side was created to allow the nuts to attack the flat pad, while the convex side was used to provide a low relief when the nut was used under the Hubcap or cover.

Modern construction continues to use a square matrix in the production of furniture objects. Square nuts are often used as a blind nut, often placed inside the metal channel to prevent rotation, forThis is tightened to the seat side of the fastener. Square nuts can be slipped into the position inside the channel and create a perfect foundation for hidden fastening elements. Nuts are also used for modern railway tracks. The square matrix is ​​located inside the rail channel, where the contact with the upper and lower part of the rail, which prevents it from turning when the pressure exerts.
