Trapezoidal nut 12x3 right-hand hexagonal, steel

Product Description

Trapezoidal nut 12x3 right-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. Standard DIN 103 / ISO 2901-2904, material Steel 11SMnPb37 (1.0737), right-hand thread Tr 12x3 - parameters fully compliant with the trapezoidal screw drive standard.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

You need a screw Tr 12x3 with the same thread hand (right-hand) and the same pitch - other sizes will not fit together.

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.

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: Steel 11SMnPb37 (1.0737) - a strong base material, resistant to high axial forces in fastening 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 12x3 trapezoidal nuts used?

Typical applications of 12x3 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.
