Trapezoidal nut 40x7 right-hand hexagonal, stainless steel

Product Description

Trapezoidal nut 40x7 right-hand hexagonal, stainless steel

A well-chosen trapezoidal nut limits backlash in the mechanism and extends the service life of the entire screw-and-nut system. Material: Stainless steel. Right-hand thread Tr 40x7, made in accordance with DIN 103 / ISO 2901-2904.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Trapezoidal screw Tr 40x7, right-hand - size, pitch and thread hand must be identical to the nut, otherwise the mechanism will jam.

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.

Does this nut need lubrication?

Yes, if the nut works in sliding motion - grease limits friction in the thread and protects it against accelerated wear, despite the material's corrosion resistance.

What are the properties of this nut's material?

Material: Stainless steel - corrosion resistance in damp environments and in contact with cleaning agents, without additional surface protection.

How is this nut mounted in the mechanism?

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

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.

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.
