Screws of pitch M4×0.25 are similar in dimensions. They are: 870-0095, 870-0095M, 870-0095ML, 870-0095MN, and 870-0095MF. You may order lockable versions of our positioners. There are different locking mechanisms. They lock a Fine Screw, while causing a slightest displacement possible. A lock at each Fine Screw is tightened with a hex key. For lockable versions append letter "L" to the code of the standard unit.

Fixing nuts 3N6X05 (for 870-0090) and 3N8X1 (for 870-0095) are available for screws with threaded collar. It will allow to fix the screw at any depth in walls too thin for the 6 mm collar thread. It will fix a screw so that the locking screw is in desired orientation. In case the unit’s wall is thin we include a fixing nut with a screw. In other case you may order the nut separately.
