Trapezoidal nut 40x7 right-hand flanged, bronze

Product Description

Trapezoidal nut 40x7 right-hand flanged, 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 CuSn5Zn5Pb5-C (CC491K), right-hand thread Tr 40x7, in accordance with DIN 103 / ISO 2901-2904.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Trapezoidal screw Tr 40x7, right-hand - size, pitch and thread hand must be identical to the nut, otherwise the mechanism will jam.

Does this nut need lubrication?

Yes, and do not skimp on grease - this nut works in sliding motion under load, and a lack of it shortens the thread's service life.

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.

What are the properties of this nut's material?

Material: Tin bronze CuSn5Zn5Pb5-C (CC491K) - 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 holes in the flange allow the nut to be screwed directly to the moving part of the machine, without an intermediate sleeve.

Where are 40x7 trapezoidal nuts used?

Typical applications of 40x7 nuts are: presses and screw jacks, machine vices, height adjustment mechanisms, sliding tables and axis drives in machine tools - wherever precise conversion of rotary into linear motion matters.
