Trapezoidal nut 16x4 left-hand flanged, bronze

Product Description

Trapezoidal nut 16x4 left-hand flanged, bronze

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 Tin bronze CuSn5Zn5Pb5-C (CC491K), left-hand thread Tr 16x4 (standard DIN 103 / ISO 2901-2904).

Technical data

Frequently asked questions

Which trapezoidal screw fits this nut?

Selection is simple: the same designation Tr 16x4, the same thread hand (left-hand) - nothing else needs to be checked.

What does the symbol Tr 16x4 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 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.

Does this nut need lubrication?

Yes - good grease is recommended, because this is a sliding element working under load. Lack of lubrication accelerates thread wear.

What are the properties of this nut's material?

Material: Tin bronze CuSn5Zn5Pb5-C (CC491K) - low tendency to seize when paired with a steel screw, the standard in screw-and-nut drives.

How is this nut mounted in the mechanism?

The flange with mounting holes allows quick, rigid fixing to the body without an additional housing.

Where are 16x4 trapezoidal nuts used?

Typical applications of 16x4 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.
