Trapezoidal screw 18x4 right-hand stainless A2 cut length 1m

Product Description

Trapezoidal screw 18x4 right-hand stainless A2 cut length 1m

1000 mm is the length that covers most typical applications in linear drives, which is why we keep it in stock as ready cut lengths. Made of stainless steel INOX A2 - AISI 304 (1.4301), compliant with DIN 103 / ISO 2901-2904, right-hand thread Tr 18x4.

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 18x4 with the same thread hand (right-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 18x4 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.
