DIN 1804 Round Slotted Nut
FLOK supplies DIN 1804 round slotted nuts wholesale: carbon steel in property classes 8 and 10 and stainless steel A2/A4, sizes M8–M75.
DIN 1804 is a manufacturing standard for round slotted nuts with an internal fine metric thread. A distinctive feature of this nut is its cylindrical shape and 4 to 8 side holes for tightening.
This type of fastener is designed for installation in confined spaces where a standard wrench cannot be used. A special hook-shaped wrench is used for tightening, providing secure fastening of the hardware. The nut is used together with various bolts, screws, studs and washers.
Materials and dimensions
Round nuts with slots are made of carbon steel, and a protective coating may be provided. The metal has property class 8 or 10, designed for significant loads. Stainless steel A2 and A4, resistant to corrosive environments, is also used. The product has a fine thread pitch: this increases the number of threads and improves fastening strength.
Dimensional characteristics:
- Thread diameter in the hole — from M8 to M75.
- Thread pitch — from 1 to 1.75 mm.
- Overall height of the product — from 5 to 14 mm.
- Maximum nut diameter — from 20 to 110 mm.
Similar fasteners are manufactured in accordance with the Russian standard GOST 11871-88.
Applications
Round slotted nuts are used in various branches of mechanical engineering. The fastener is used for installation in mechanisms and units with limited access to the connection. The shape of the nut and the side slots allow it to be tightened without a standard wrench, with a special tool providing high tightening torque.
This type of fastener is used in automotive manufacturing, machine tool building, instrument production, special equipment, and various vehicles. The nuts are designed for long-term use due to their strength and corrosion resistance.
