Screw cylindrical head - hex DIN 912 M30x120-12.9

Product detailed description

The cylinder head screw with internal hexagon, designated as DIN 912 M30x120-12.9, is intended for applications requiring high preload in bolted joints. This screw is made of steel with a strength class of 12.9, which means that it has a high tensile strength and is suitable for demanding mechanical applications where high resistance to stress is required. The screw has no surface treatment, it is blackened, which provides basic protection against corrosion.

Structurally, this screw is equipped with a cylinder head with internal hexagon, which allows it to be mounted using an Allen key. This type of head is ideal for applications where it is necessary to minimize the height of the head above the material surface. The dimensions of the screw are as follows: the thread diameter is M30, the total length of the screw is 120 mm, while the thread length is 72 mm. The head diameter is 45 mm, the B1 width is 22 mm and the head height is 30 mm. The screw has a metric thread with a pitch of 3.50 mm.

This screw complies with DIN 912, ISO 4762 and ČSN 021143, which guarantees its compatibility and standardization within international and national regulations. It is suitable for use in various industrial sectors where it is necessary to ensure a strong and reliable connection of components. The screw is supplied in a package of one piece, which allows flexibility in ordering the exact quantity required for a specific application.
