Trapezoidal nut 20x4 right-hand square, brass

Product Description

Trapezoidal nut 20x4 right-hand square, brass

A well-chosen trapezoidal nut limits backlash in the mechanism and extends the service life of the entire screw-and-nut system. Made of Brass CW614N-M (ex OT58), right-hand thread Tr 20x4, 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 20x4, the same thread hand (right-hand) - nothing else needs to be checked.

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.

Does this nut need lubrication?

Yes, grease is recommended - the loads are low, but wear resistance without lubrication is limited.

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: Brass CW614N-M (ex OT58) - good corrosion resistance and a low coefficient of friction, a popular choice in lighter applications.

How is this nut mounted in the mechanism?

The square outline alone is enough to lock rotation - without the need for a key or locating pin.

Where are 20x4 trapezoidal nuts used?

Typical applications of 20x4 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.
