Leveling sets: Stainless steel, European Standard 1.4305 (American Standard series 303)

GN 350.2-NI leveling sets are used for leveling, adjusting, and linking operations.
The spherical washer allows precise installation of two non-parallel planes at a required gradient up to ~4°.
Leveling sets consist of a threaded upper sleeve and a tapped lower sleeve. The fine thread allows precise, stepless setting and locking using a DIN 1810A hook wrench. An anti-rotation disk serves also as a height limiter for the maximum height.
Normally this screw is permanently and securely locked by the static load created when the mounting screw is tightened. If this is not sufficient, the use of a locknut (Type AK) is recommended.
