Nut trapezoidal hexagonal left thread DIN 103 Tr12x3

Product detailed description

Trapezoidal hexagon nut with left-hand thread according to DIN 103, size Tr12x3, is designed for applications where it is necessary to transmit higher axial forces with lower friction. Trapezoidal thread, characterized by its profile in the shape of an isosceles trapezoid, provides higher mechanical resistance and efficiency in transmitting forces compared to conventional metric threads. This type of thread is often used in lifting mechanisms, such as jacks or presses, where reliability and accuracy of movement are required.

The nut is made of C15 grade steel, which is a low-carbon steel that provides sufficient strength and toughness for common mechanical applications. C15 steel is suitable for components that do not require high strength or wear resistance. The nut has no surface treatment, which means that it is more susceptible to corrosion and is suitable for use in dry and non-corrosive environments or where the surface treatment is provided by other means.

The geometric parameters of the nut are as follows: the thread diameter is Tr12x3 with a left-hand direction, which means that it is tightened counterclockwise. The thread pitch is 3.00 mm, which determines the distance the nut moves in one turn. The length of the nut is 18 mm and the width between the hexagon faces is 19 mm, which allows the use of standard wrenches for manipulation.

This nut is suitable for use in mechanisms where it is necessary to ensure reliable and precise force transmission while maintaining simplicity of design and maintenance. Due to the absence of surface treatment, corrosion protection must be considered depending on the specific environment of use.
