Split Nut

Split Nut

Compared to the standard nut, the split nut is easier to install. Moreover, it has a higher inherent strength.

Split Nut is a type of nut that is split into two equal pieces so it can be put on a shaft or bolt without disassembling it. And it has a female thread that may be opened and closed over a male thread. In order to secure the nut to the bolt, it is fitted with a conical washer.

The screw and nut are usually lubricated as well. These threads reduce thread wear and extend thread life.

A split nut usually has two machine screws to fit the two pieces. When installing, you need to install screws, otherwise, it won’t be secure. The nut’s two halves have chamfered edges, which aids thread contact during closure.

When the split nut is open, the nut slides along the screw without rotating. But, when it’s closed, it moves like a nut on a screw.

Advantages of Split Nuts

  • Reduces the maximum tensile stress at the root of the thread to approximately half of the maximum tensile stress in the typical nut.
  • Reduces the bending stress at the thread root.
  • The thread load distribution is improved.
  • It has a higher inherent strength.
  • Split nuts are easier to install

Applications of Split Nuts

Split nuts are commonly used to give extra support to rods, threads, and blots. However, it’s also used in positioning systems such as in lathe machines. Furthermore, electricians also use it to combine wires.
