Hexagon screw with partial thread DIN 931 M12x250-8.8 galvanized

Product detailed description

The partially threaded hexagonal bolt according to DIN 931, ISO 4014 and ČSN 021101 is designed for applications requiring high strength and reliability of joints. This bolt has a metric thread with a diameter of M12 and a length of 250 mm, with a thread pitch of 1.75 mm. The partial thread allows for better stress distribution in the joint, which is advantageous when used in mechanical engineering, construction and assembly assemblies, where joints are exposed to higher stress.

The head of the bolt has a hexagonal shape with dimensions of width s 19 mm and width e 21.1 mm, which allows the use of standard wrenches for manipulation. The head height is 7.5 mm, which provides sufficient space for applying torque during assembly. The screw is made of steel with a strength class of 8.8, which means that it has a yield strength of 640 MPa and a tensile strength of 800 MPa. This strength class is suitable for applications where higher mechanical properties are required.

The surface treatment of the screw is white zinc plating, which provides protection against corrosion and increases resistance to external influences. Zinc plating is a galvanic process that creates a protective layer on the surface of the steel, thereby extending the service life of the component in harsh conditions. The screw is suitable for use in various industrial sectors where high reliability and durability of connections are required.
