The DIRAK M6x12 Grounding Countersunk Screws with Segment Cutting Edge and Scraping Tooth

A Conductive Connection

The main purpose of potential equalization is as a protective measure against electric shock and overvoltage. In case of error, for example if a part of the housing is carrying voltage, this would lead to a hazard for persons and operating equipment. Painted or powder-coated metallic base materials cannot be used without pretreatment of the points that connect into the potential equalization. If conventional fastening elements are used, the contact surface must be bare or kept free of paint. This step is time-consuming and cost-intensive.

Grounding countersunk screws, developed by DIRAK and certified by the VDE (Association of German Electrical Engineers), are fitted under the screw head with a segment cutting edge and scraping tooth. This unparalleled advancement allows for electrical and mechanical contact with metallic base materials without extensive pretreatment. Grounding countersunk screws ensure potential equalization in both a counterbore and a cylindrical bore. DIRAK offers the M6x12 grounding countersunk screws with a metric thread cutting and a standardized metric thread.
