Trapezoidal screw 40x7 right-hand stainless A2 cut length 0,5m

Product Description

Trapezoidal screw 40x7 right-hand stainless A2 cut length 0,5m

500 mm is the length that is most often enough in small service mechanisms - you buy a ready part, not metres to cut. Made of stainless steel INOX A2 - AISI 304 (1.4301), 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: installations working in damp environments, washing systems, the food and chemical industries - A2 steel does not corrode under the influence of water and most cleaning agents.

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.

What does the symbol Tr 40x7 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.
