Screw cylindrical head - hex DIN 912 M30x140-10.9

Product detailed description

The cylinder head screw with internal hexagon, also known as an Allen screw, is manufactured according to DIN 912, ISO 4762 and ČSN 021143 standards. This component is intended for fixed screw connections that require high preload, which is ensured by the use of steel with strength class 10.9. The screw has a metric thread with a diameter of M30 and a length of 140 mm, while the thread length is 72 mm. The thread pitch is 3.50 mm.

The screw head has a cylindrical shape with a diameter of 45 mm and a height of 30 mm. The internal hexagon allows assembly using an Allen key, which is practical in applications where precise and firm tightening is required. The width B1, which represents the distance between two parallel faces inside the hexagon, is 22 mm.

The screw material is unalloyed steel without surface treatment, which means that it is suitable for applications where additional corrosion protection is not required. This type of screw is ideal for use in engineering and construction, where high mechanical properties and reliability of connections are required. The screw is part of a group of fasteners that are often used in industrial applications where high strength and precision are required.
