Detailed item description for DIN 933 hexagon screws, thread up to the head

DIN 933 hexagon screws, thread up to the head are screws with a thread where the head is shaped like an external hexagon. They are the TOP product in the screw trade. The thread extends up to the head. Due to production reasons, there may be a small threadless gap between the underside of the head and the thread. They do not have a drive in the head, here the head itself drives the screw. It is moved with a ring or open-end wrench. Hexagon screws are often used in mechanical and plant engineering, in cars, vintage cars, motorcycles, agricultural machinery, trucks or in measurement and electrical engineering.

Hexagon screws manufactured in accordance with DIN 933 are among the most widely used threaded screws of all. The range of hexagon screws according to DIN 933 is accordingly extensive. Typical of hexagon screws according to DIN 933, which are also often referred to as machine screws, is the continuous thread that extends almost to the screw head. This feature means that hexagon screws according to DIN 933 can be used for all fastening requirements where a full thread is required or desired. Machine screws according to DIN 933 are probably the most commonly used screw types worldwide, alongside cylinder screws.

Hexagon screws according to DIN 933: Areas of use

Hexagon screws according to DIN 933 are used in mechanical and plant engineering, in the interior and exterior of houses, in the garden or in the hobby sector. Hexagon screws in accordance with DIN 933 are used wherever permanent screw connections need to be made quickly and cheaply. Thanks to the countless, variable dimensions, there is a suitable hexagon screw for almost every application. There is also a wide range of materials to choose from. From rust-proof stainless steel screws to brass and steel versions, every hexagon screw can be purchased inexpensively to meet your exact requirements.

Advantages of DIN 933 hexagon screws, thread to head

Unlike slotted or Phillips screws, external hexagon screws can also be used when the screw head is no longer accessible from above. In addition, hexagon screws are suitable when there is a lack of space due to their relatively low head height.

Materials for DIN 933 hexagon screws, thread to head

Hexagon screws for outdoor use should be made of at least A2 stainless steel. If there is permanent contact with water or temporary contact with salt water or acids, they should be made of A4 stainless steel. For applications in steel construction or mechanical engineering, high-strength screws with strengths of 8.8, 10.9 or 12.9 are available. These are available either bare or surface-treated (e.g. electrogalvanized or hot-dip galvanized).
