Trapezoidal nut 14x4 left-hand hexagonal, steel

Product Description

Trapezoidal nut 14x4 left-hand hexagonal, steel

In many machines it is this nut, not the screw, that wears first - which is why the quality of the material and the thread is particularly important here. Product made of Steel 11SMnPb37 (1.0737), left-hand thread Tr 14x4 (standard DIN 103 / ISO 2901-2904).

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Selection is simple: the same designation Tr 14x4, the same thread hand (left-hand) - nothing else needs to be checked.

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.

Does this nut need lubrication?

No - it is a fastening/self-locking element that does not work in sliding motion under load, so it does not need lubrication.

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?

A shape known from classic nuts - easy mounting with an open-end or ring spanner.

Where are 14x4 trapezoidal nuts used?

Typical applications of 14x4 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.
