Features of DIN fasteners 933 and DIN 912, used in various fields

Fasteners are used in many areas of production. You can’t do without it in furniture, construction, automotive, plane-, shipbuilding industry. bolts, screws, nuts, screws are present in most industrial products, from wooden boxes to laptops and other high-tech devices.

What is DIN 933

According to international standard FROM 933 is a bolt, equipped with hex head. This metal product can be made from durable steel (with or without coating), aluminum, brass, copper alloy, titanium. Hot zinc coating protects steel from rusting. For the same purposes, the black oxidation technique is used.. Typically DIN bolt thread 933 chopped to the head.

Such bolts can be used in construction, mechanical engineering, production of metal structures, furniture manufacturing. They are characterized by high strength, durability. Protective coating and alloys, not subject to rust, provide long service life of hardware without loss of strength declared by the manufacturer.

What kind of product is DIN 912

This metal product is also used in various industries.. It consists of cylindrical head screws. Their main difference from conventional self-tapping screws is that, that their head has a hexagonal recess for a special key. Screw FROM 912 made of titanium, of stainless steel. Besides, For the production of hardware, ordinary steel and zinc-coated material are used, zinc lamella, black oxidation.

Screws are characterized by increased strength, reliability and durability. Titanium metal products are used in the production of equipment, which is subject to increased loads. The screws withstand mechanical, temperature, vibration effects.

What to consider when choosing fasteners

When choosing fasteners, their purpose is taken into account (building, furniture, engineering fasteners). Moreover, the length of the products is important, pitch and thread features, head diameter, slot shape. If the products will be exposed to high humidity, it is recommended to give preference to stainless steel fasteners. In some cases, it is advisable to purchase anti-vandal fasteners with countersunk heads or removable slots.
