NEFF Trapezoidal Nuts

NEFF-trapezoidal screws are manufactured from special semi-finish goods with high demands on straightness. The series conforms to DIN 103 and offers a wide range of nuts made of different kinds of material. Das geringe Mutternspiel erlaubt die Aufnahme radialer Kräfte.

KSM steel nut, round Ø 10 – 80 mm

Suitable for clamping operations, manual positioning and mounting. Not suitable for motion drives because the steel/steel friction tends to seizure.

Further processing:The thread serves as reference for precise machining and assembly.
Material: free-cutting steel 1.0718 (9 SMn 28K).
