Trapezoidal nut 40x7 right-hand hexagonal, steel

Product Description

Trapezoidal nut 40x7 right-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), right-hand thread Tr 40x7 (standard DIN 103 / ISO 2901-2904).

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

You need a screw Tr 40x7 with the same thread hand (right-hand) and the same pitch - other sizes will not fit together.

How can you tell that a trapezoidal nut is worn?

The most common sign is increasing backlash between the screw and the nut - noticeable jerking when the direction of motion changes. This means the nut thread has worn and needs to be replaced.

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 does the symbol Tr 40x7 mean?

"Tr" is a symmetrical trapezoidal thread (flank angle 30°). The first number is the outer diameter of the screw in millimetres, the second is the thread pitch, i.e. the linear travel per full turn.

What are the properties of this nut's material?

Material: Steel 11SMnPb37 (1.0737) - structural steel with good machinability, used where the nut works as a fastening element, not a sliding one.

How is this nut mounted in the mechanism?

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

Where are 40x7 trapezoidal nuts used?

40x7 trapezoidal nuts are used in screw jacks, presses, vices, positioning tables, linear axes of CNC machines and tensioning mechanisms - wherever the rotary motion of a screw must be converted into precise, repeatable linear motion.
