Screw cylindrical head - hex DIN 912 M6x90-12.9

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 screw has a metric thread with dimensions M6 x 90 mm, with a thread length of 24 mm. The thread diameter is M6, the head diameter is 10 mm, the width of the groove for the internal hexagon is 5 mm and the head height is 6 mm. The screw is made of steel with a strength class of 12.9, which means that it is able to withstand high mechanical stress and is suitable for applications requiring high preload. The surface treatment is untreated or blackened, which can improve corrosion resistance in certain conditions. The screw is intended for fixed screw connections and is suitable for assembly using an Allen key, which allows for effective torque transmission and reduces the risk of damage to the screw head. This type of screw is often used in mechanical engineering, the automotive industry and other technical sectors where high demands are placed on the strength and reliability of connections.
