Product Description
Trapezoidal screw 40x7 left-hand stainless A2 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 stainless steel INOX A2 - AISI 304 (1.4301), compliant with DIN 103 / ISO 2901-2904, left-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.

Frequently asked questions
Which nut fits this cut length?
A trapezoidal nut Tr 40x7 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 40x7 as a by-the-metre version for individual cutting.
In what conditions is it worth choosing the stainless version?
Where the screw comes into contact with water, moisture or cleaning agents - stainless steel then needs no additional corrosion protection, unlike carbon steel.
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.
