Trapezoidal screw 22x5 left-hand C45 cut length 0,5m

Product Description

Trapezoidal screw 22x5 left-hand C45 cut length 0,5m

A short, ready 500 mm cut length works well where length accuracy matters more than running metres - e.g. in small positioning mechanisms. Made of carbon steel C45 (1.0503), compliant with DIN 103 / ISO 2901-2904, left-hand thread Tr 22x5.

Works with a trapezoidal nut with the same thread (size, pitch and hand must be identical). Used in: lifting jacks, presses and vices working under higher loads - the higher surface hardness of C45 steel (approx. 250 HB, compared with approx. 160-180 HB for C15E) copes better with friction and working pressure.

Technical data

Frequently asked questions

Which nut fits this cut length?

A trapezoidal nut Tr 22x5 with the same thread hand (left-hand) - size and pitch must be identical, otherwise the mechanism will jam.

How does this ready cut length differ from the screw sold by the metre?

This product has a fixed, ready length of 500 mm - it requires no cutting and no surcharge for the service. You will also find the screw Tr 22x5 as a by-the-metre version for individual cutting.

Does this screw need lubrication?

Yes. The bronze nut working with it needs good grease during operation - the C45 steel screw itself has low surface roughness, which limits friction.

Is there backlash in a trapezoidal screw drive?

Yes - a standard trapezoidal nut has some backlash resulting from the manufacturing tolerance of the thread. If the mechanism requires zero backlash (e.g. for precise positioning in CNC machine tools), it is worth using a backlash-reducing (anti-backlash) nut that works with this screw.
