Trapezoidal nut 40x7 left-hand cylindrical, steel

Product Description

Trapezoidal nut 40x7 left-hand cylindrical, steel

This element is always selected together with the screw - without matching size, pitch and thread hand the mechanism will not fit together. Standard DIN 103 / ISO 2901-2904, material Steel 11SMnPb37 (1.0737), left-hand thread Tr 40x7 - parameters fully compliant with the trapezoidal screw drive standard.

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Selection is simple: the same designation Tr 40x7, the same thread hand (left-hand) - nothing else needs to be checked.

What does the symbol Tr 40x7 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?

No - it is a fastening/self-locking element that does not work in sliding motion under load, so it does not need lubrication.

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.

What are the properties of this nut's material?

Material: Steel 11SMnPb37 (1.0737) - the hardness and rigidity of the material cope well with static loads in self-locking 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 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.
