DIN 925 Countersunk Head Screw with Slot and Pin

The screw, made to DIN 925, is used to create a strong connection between parts made of metal, plastic and other materials, securely fixing them in the required position. The fastener is fitted with a countersunk head, which sits fully flush with the surface and does not protrude above it. For ease of driving, the head has a slot, and the end of the screw is fitted with a cylindrical pin. The countersunk screw is additionally equipped with a neck under the head for reliable fixation in the material.

Features and specifications of the fastener

The fastener is made of steel with property class 5.8; to increase corrosion resistance it may be supplied with an anticorrosive zinc coating. For use in highly corrosive environments, screws made of stainless steel A1-A5 are used — these alloys have enhanced acid resistance.

This type of fastener has the following technical characteristics:

• Nominal thread diameter – from M1.4 to M3.
• Head diameter – from 2.6 to 5.6 mm.
• Head height can range from 0.84 to 1.65 mm.

It differs from its closest counterpart, DIN 924, in head configuration. The countersunk head allows for flush connections, as it sits fully recessed into the prepared hole.

Applications

The fastener is suitable for use in mechanical engineering, machine tool building, instrument making and other industrial sectors. The screw is used in the assembly of parts for various purposes, and its configuration ensures the reliability of the threaded connection.
