Trapezoidal nut 44x7 left-hand cylindrical, steel

Product Description

Trapezoidal nut 44x7 left-hand cylindrical, steel

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. Product made of Steel 11SMnPb37 (1.0737), left-hand thread Tr 44x7 (standard DIN 103 / ISO 2901-2904).

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Selection is simple: the same designation Tr 44x7, 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.

What does the symbol Tr 44x7 mean?

The designation "Tr" indicates a trapezoidal thread with a symmetrical 30° profile. The first number is the nominal diameter in mm, the second is the pitch - the distance the nut travels per turn of the screw.

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.

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?

The smooth, round outline allows the nut to be seated in a recessed socket, without protruding edges.

Where are 44x7 trapezoidal nuts used?

Typical applications of 44x7 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.
