Trapezoidal nut 12x3 right-hand flanged, bronze

Product Description

Trapezoidal nut 12x3 right-hand flanged, bronze

This element is always selected together with the screw - without matching size, pitch and thread hand the mechanism will not fit together. Material: Tin bronze CuSn5Zn5Pb5-C (CC491K). 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?

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

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 - good grease is recommended, because this is a sliding element working under load. Lack of lubrication accelerates thread wear.

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 are the properties of this nut's material?

Material: Tin bronze CuSn5Zn5Pb5-C (CC491K) - a material long used in screw drives because of its favourable sliding friction coefficient.

How is this nut mounted in the mechanism?

The holes in the flange allow the nut to be screwed directly to the moving part of the machine, without an intermediate sleeve.

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.
