DIN 1804 A2 Round slotted nut

Slotted nut is a nut used to fix coaxial parts on shafts, such as bearings, bushings, ball bearings and other parts of rotation. They are usually lower and smaller in external parameters than standard hexagon nuts, but they are often used on large shafts, so a design was invented in which they can be tightened with a special wrench smaller than a regular wrench of the appropriate nut diameter. The wrench clings with a special tooth to one of the slots of the nut and, wrapping around its body, rests on it, allowing you to make an effort when turning.

Scope DIN 1804 is used on machine parts, in cars on shock absorber racks, in bicycle parts, on photographic lenses, etc.

Material stainless steel. Strength class A2 allows the use of bolts at significant temperature differences and in aggressive and humid environments.

Without coverage.

Analog GOST 11871-88
