Trapezoidal nut 12x2 right-hand cylindrical, steel

Product Description

Trapezoidal nut 12x2 right-hand cylindrical, steel

It is the basic element of every screw-and-nut drive - it converts the rotary motion of the screw into the linear motion of the mechanism. Material: Steel 11SMnPb37 (1.0737). Right-hand thread Tr 12x2, made in accordance with DIN 103 / ISO 2901-2904.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Trapezoidal screw Tr 12x2, right-hand - size, pitch and thread hand must be identical to the nut, otherwise the mechanism will jam.

What does the symbol Tr 12x2 mean?

"Tr" is a symmetrical trapezoidal thread (flank angle 30°). The first number is the outer diameter of the screw in millimetres, the second is the thread pitch, i.e. the linear travel per full turn.

Does this nut need lubrication?

No - it is a fastening/self-locking element that does not work in sliding motion under load, so it does not need lubrication.

What are the properties of this nut's material?

Material: Steel 11SMnPb37 (1.0737) - high mechanical strength, suitable for fastening and self-locking mechanisms without sliding motion under load.

How is this nut mounted in the mechanism?

The cylindrical body is designed to be installed inside a housing or mounting sleeve.

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.

Where are 12x2 trapezoidal nuts used?

12x2 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.
