Trapezoidal nut 20x4 left-hand hexagonal, steel

Product Description

Trapezoidal nut 20x4 left-hand hexagonal, steel

This element is always selected together with the screw - without matching size, pitch and thread hand the mechanism will not fit together. Product made of Steel 11SMnPb37 (1.0737), left-hand thread Tr 20x4 (standard DIN 103 / ISO 2901-2904).

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Trapezoidal screw Tr 20x4, left-hand - size, pitch and thread hand must be identical to the nut, otherwise the mechanism will jam.

Does this nut need lubrication?

There is no need - this nut works as a fastening element, not a sliding one, so grease is not required here.

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 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: Steel 11SMnPb37 (1.0737) - the hardness and rigidity of the material cope well with static loads in self-locking joints.

How is this nut mounted in the mechanism?

The hexagonal outline allows mounting and tightening with a standard spanner.

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.
