Countersunk Allen screw DIN 7991 M3x20-10.9 galvanized

Product detailed description

The DIN 7991 M3x20-10.9 zinc-plated countersunk head screw is a high-quality fastener designed for applications requiring a strong and reliable connection. This screw is made of 10.9 strength steel, which guarantees its high mechanical resistance and ability to carry significant loads. The zinc-plated surface treatment provides protection against corrosion, thus extending the life of the screw even in harsh conditions.

The screw has a metric thread with a diameter of M3 and a pitch of 0.50 mm, which is standard for this type of thread. The total length of the screw is 20 mm. The screw head is countersunk with an internal hexagon, which allows it to be embedded in the material so that the surface of the joint remains flat. This design is ideal for metal and structural applications where it is necessary to minimize protrusions on the surface.

According to DIN 7991 and ISO 10642, the screw meets all requirements for accuracy and quality. The head dimensions are optimized for efficient force distribution: the head height is 1.2 mm, the head diameter is 6 mm and the width for the internal hexagon is 2 mm. The countersunk head angle is 90°, which is standard for this type of screw and ensures optimal embedment in the material.

This screw is suitable for use in various industrial sectors where it is necessary to ensure a strong and reliable connection with minimal visual and functional disruption of the surface. It is ideal for applications where aesthetics and functionality of the joints are important, such as metal structures, machines and equipment.
