Trapezoidal nut 14x4 right-hand cylindrical, bronze

Product Description

Trapezoidal nut 14x4 right-hand cylindrical, bronze

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 Tin bronze CuSn7Zn4Pb7-C (CC493K), right-hand thread Tr 14x4, in accordance with DIN 103 / ISO 2901-2904.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

You need a screw Tr 14x4 with the same thread hand (right-hand) and the same pitch - other sizes will not fit together.

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 14x4 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 a standard trapezoidal nut have backlash in the thread?

Yes, some backlash results from the manufacturing tolerance of the thread - this is normal. If you need zero backlash (e.g. for precise positioning), anti-backlash nuts are used, which are a different product from a standard nut.

What are the properties of this nut's material?

Material: Tin bronze CuSn7Zn4Pb7-C (CC493K) - it dampens microscopic irregularities of the thread well, which extends the service life of the mating screw.

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 14x4 trapezoidal nuts used?

14x4 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.
