Trapezoidal screw 14x4 left-hand C15 cut length 0,5m

Product Description

Trapezoidal screw 14x4 left-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, left-hand thread Tr 14x4.

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 14x4 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 14x4 as a by-the-metre version for individual cutting.

What does the symbol Tr 14x4 mean?

"Tr" is a symmetrical trapezoidal thread (flank angle 30°) compliant with DIN 103 / ISO 2901-2904. The first number is the outer diameter of the screw in millimetres, the second is the thread pitch, i.e. the linear travel of the nut for one full 360° turn of the screw.

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.
