DIN 964 Raised Countersunk Head Screw (Slotted)

DIN 964 covers fastening screws with a raised countersunk head and full metric thread along the shank. The head has a slot, allowing it to be driven with a screwdriver or power tool.

The product is installed into a prepared hole in the parts and secured with nuts and washers of matching diameter. The screw is used to assemble strong detachable joints and is in demand across various industrial sectors. Similar fasteners are manufactured to GOST 17474, ISO 2010.

Application scope and features of the fastener

DIN 964 screws are manufactured with thread running the full length of the shank. Thread diameter ranges from M2 to M10, length from 4 to 100 mm. The fastener is installed into a pre-tapped threaded hole. The head is half-recessed into the material, giving the joint a good decorative appearance.

The screws are made of class 4.8 steel, which can be galvanically zinc-plated to improve corrosion resistance. Stainless steel grades A1, A2 and A4 are also used — these materials resist moisture and aggressive chemical environments.

DIN 964 screws are a universal fastener for various manufacturing sectors: mechanical engineering, machine tool building, instrument making and others. Thanks to the head shape, they are also suitable for furniture production, construction and finishing work. The fastener ensures a reliable connection of structures.
