Trapezoidal nut 40x7 right-hand cylindrical, bronze

Product Description

Trapezoidal nut 40x7 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. Material: Tin bronze CuSn7Zn4Pb7-C (CC493K). Right-hand thread Tr 40x7, made in accordance with DIN 103 / ISO 2901-2904.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

You need a screw Tr 40x7 with the same thread hand (right-hand) and the same pitch - other sizes will not fit together.

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.

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.

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.

What are the properties of this nut's material?

Material: Tin bronze CuSn7Zn4Pb7-C (CC493K) - good sliding properties and a low coefficient of friction in the thread, typical of nuts working in motion.

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 40x7 trapezoidal nuts used?

40x7 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.
