Slotted Round Nut

The slotted round nut with a fine metric thread provides reliable and precise fastening to the surface. The DIN 70852 fastener is used in mechanical engineering, manufacturing, and construction work of varying complexity. The nut has special slots that fit a semicircular wrench. This type of fastener is most often used for mounting bearings on rotating shafts, as well as when working with circular saw blades at woodworking facilities.

To increase the reliability and precision of fastening, a multi-prong lock washer DIN 5406 is often used. The nut is used exclusively together with fasteners of the corresponding thread size — matching studs, screws, and bolts.

The fastener is made of steel with good wear-resistance properties. If required, a galvanic zinc coating is available, protecting the fastener from corrosion in high-humidity conditions.
