Trapezoidal nut 12x3 right-hand cylindrical, steel

Product Description

Trapezoidal nut 12x3 right-hand cylindrical, steel

The nut works with a trapezoidal screw with the same thread - choosing the correct size and thread hand is key to the correct operation of the mechanism. Made of Steel 11SMnPb37 (1.0737), right-hand thread Tr 12x3, in accordance with DIN 103 / ISO 2901-2904.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Selection is simple: the same designation Tr 12x3, the same thread hand (right-hand) - nothing else needs to be checked.

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.

How do the material families of trapezoidal nuts differ?

Steel is chosen for fastening joints without sliding motion, bronze for drives with continuous sliding motion (low friction), and brass for lighter applications where moisture resistance matters at a lower cost than bronze.

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.

What are the properties of this nut's material?

Material: Steel 11SMnPb37 (1.0737) - the hardness and rigidity of the material cope well with static loads in self-locking joints.

How is this nut mounted in the mechanism?

The smooth, round outline allows the nut to be seated in a recessed socket, without protruding edges.

Where are 12x3 trapezoidal nuts used?

12x3 trapezoidal nuts are used in screw jacks, presses, vices, positioning tables, linear axes of CNC machines and tensioning mechanisms - wherever the rotary motion of a screw must be converted into precise, repeatable linear motion.
