Trapezoidal nut 28x5 right-hand hexagonal, steel

Product Description

Trapezoidal nut 28x5 right-hand hexagonal, 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), right-hand thread Tr 28x5 (standard DIN 103 / ISO 2901-2904).

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Selection is simple: the same designation Tr 28x5, the same thread hand (right-hand) - nothing else needs to be checked.

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.

What does the symbol Tr 28x5 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.

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) - high mechanical strength, suitable for fastening and self-locking mechanisms without sliding motion under load.

How is this nut mounted in the mechanism?

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

Where are 28x5 trapezoidal nuts used?

Typical applications of 28x5 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.
