The main characteristics of the fastening element din 912
EUROBOLT-Ukraine offers a screw with a cylindrical head and internal hexagon DIN 912, provided in all standard sizes and variations. Our regional and regional representative offices, as well as offices in Kyiv, are open for cooperation with customers and distributors. Eurobolt Ukraine is a reasonable price, high quality and the fastest possible delivery.
DIN 912 is a standardized high-strength metal pin with an inch thread applied to the shaft and an enlarged cylindrical head. For installation, you will need a tool (electric or manual) with hexagon sockets, as well as hexagon nuts or other fixing elements with the appropriate thread.
Functional features
Cap screws and hexagon socket head screws differ from each other: the production line includes different sizes, alternative recess shapes, thread pitch and protective coating. General qualities for fasteners of this category are: ease of installation; long service life; strength of connections; minimization of involuntary unwinding; the possibility of automated use/assembly of the screw and its fixing elements (relevant for production scales). Some user reviews noted the admissibility of din 912 metalwork to multiple assembly-disassembly cycles. Thanks to the well-thought-out design and high-quality raw materials, such types of slot are reliably protected against rapid wear. Here you can buy a screw with a cylindrical head and an internal hexagon with normal or improved indicators of wear resistance, resistance to moisture / high or low temperatures / chemical compounds.
Analogues of DIN 912:
ISO 4762 – Hex socket head cap screws with large pitch metric threads. ISO 12474 – Hex socket head cap screws with fine pitch metric threads. ISO 14579 – screws with a cylindrical head and a recess for a TORX socket. DIN 6912 – screws with a low cylindrical head and a hexagonal recess under the key. DIN 7984 – screws with a low cylindrical head and a hexagonal recess under the key. GOST 11738-84 – screws with a cylindrical head and a hexagonal recess under the key of accuracy class A with a thread diameter from 3 to 36 mm.
