Trapezoidal nut 12x3 right-hand square, brass

Product Description

Trapezoidal nut 12x3 right-hand square, brass

In many machines it is this nut, not the screw, that wears first - which is why the quality of the material and the thread is particularly important here. Material: Brass CW614N-M (ex OT58). Right-hand thread Tr 12x3, made in accordance with DIN 103 / ISO 2901-2904.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Trapezoidal screw Tr 12x3, right-hand - size, pitch and thread hand must be identical to the nut, otherwise the mechanism will jam.

What does the symbol Tr 12x3 mean?

The designation "Tr" indicates a trapezoidal thread with a symmetrical 30° profile. The first number is the nominal diameter in mm, the second is the pitch - the distance the nut travels per turn of the screw.

Does this nut need lubrication?

Yes, grease is recommended - the loads are low, but wear resistance without lubrication is limited.

How can you tell that a trapezoidal nut is worn?

The most common sign is increasing backlash between the screw and the nut - noticeable jerking when the direction of motion changes. This means the nut thread has worn and needs to be replaced.

What are the properties of this nut's material?

Material: Brass CW614N-M (ex OT58) - easy machinability and moisture resistance, suitable for mechanisms working under moderate loads.

How is this nut mounted in the mechanism?

The square outline prevents rotation in a guide seat with a matching cross-section.

Where are 12x3 trapezoidal nuts used?

Typical applications of 12x3 nuts are: presses and screw jacks, machine vices, height adjustment mechanisms, sliding tables and axis drives in machine tools - wherever precise conversion of rotary into linear motion matters.
