DIN 926 Headless Screw with Slot and Dog Point

The headless screw with slot and dog point is manufactured to the German standard DIN 926. It is installed into a pre-tapped threaded hole of the matching diameter and fully recesses into the material without protruding above the surface. A slot is provided at the end face of the screw for driving with a flat-blade screwdriver. A cylindrical dog point is provided at the opposite end. The fastener has a full metric thread with a diameter from M1 to M6.

Materials and application

Fasteners to DIN 926 are made of steel with a hardness of 14H; the metal may be electroplated with zinc or nickel coating. For installation in corrosive environments, screws made of stainless steel grades A1-A5 are used. Such products have increased resistance to aggressive exposure. Non-ferrous alloys, such as brass, may also be used in manufacturing.

Fasteners of this type are intended for assembling machine parts and various units. They are used in machine building, instrument engineering, and the production of machine tools and other industrial equipment.
