Trapezoidal screw 40x7 right-hand C15 cut length 0,5m

Product Description

Trapezoidal screw 40x7 right-hand C15 cut length 0,5m

This cut length already has a fixed length of 500 mm, so it goes to stock and to assembly without cutting to size. Made of carbon steel C15E (1.1141), compliant with DIN 103 / ISO 2901-2904, right-hand thread Tr 40x7.

Works with a trapezoidal nut with the same thread (size, pitch and hand must be identical). Used in: lifting jacks, presses, vices, conventional machine tools, valves, welding positioners and tensioning mechanisms of agricultural machinery.

Technical data

Frequently asked questions

Which nut fits this cut length?

A trapezoidal nut Tr 40x7 with the same thread hand (right-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 40x7 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 C15E 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.
