Trapezoidal screw 20x4 left-hand stainless A2 cut length 1m

Product Description

Trapezoidal screw 20x4 left-hand stainless A2 cut length 1m

A one-metre cut length is the most frequently chosen length for linear drives - it is in stock right away, so service does not wait for cutting but simply installs it. Made of stainless steel INOX A2 - AISI 304 (1.4301), compliant with DIN 103 / ISO 2901-2904, left-hand thread Tr 20x4.

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 20x4 with the same thread hand (left-hand) - size and pitch must be identical, otherwise the mechanism will jam.

Can I order a length other than 1000 mm?

Yes, the screw Tr 20x4 is also available by the metre for individual cutting - this product is a ready, fixed cut length of 1000 mm.

Does this screw need lubrication?

Yes, despite its corrosion resistance - grease limits friction in the thread and protects the mating nut against accelerated wear.

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.
