DIN 548 Round Nut with Radial Holes

Round nuts with radial holes in the end face are manufactured to DIN 548. This type of fastener is suitable for use in restricted-access conditions: nuts of this type are tightened and loosened from the end face using the special holes.

The round disc has a threaded central hole, and the nut is used together with bolts, screws, and threaded studs. This type of fastener is used to secure various assemblies of units and devices and is widely used in industry.

Materials

Fasteners to DIN 548 are made of carbon steel and may feature zinc, chrome, or nickel plating for corrosion protection. The nuts are also made of stainless steel grades A1-A5 – these are not subject to corrosion and can be used in chemically aggressive environments or high-humidity conditions.
