DIN934 Carbon steel Grade 4.8 with Black plated Hex Nut'
Utilizing high-precision cold heading technology, the thread pitch is uniform, without burrs. They can be screwed in smoothly without any jamming, eliminating the "locking" phenomenon, significantly enhancing the assembly efficiency.
We refuse to cut corners. We strictly control the dimensions of the flange (S) and the leg (e), and we reject "thin-walled" nuts to ensure that the force-bearing surface of the wrench is sufficient and to prevent slipping.
Application
Construction machinery: Excavators, tower cranes, heavy equipment (emphasizing high strength)
Facade installation: Exterior wall dry hanging, steel structure (emphasizing rust prevention and complete specifications)
Electronics/Furniture: Precision instruments, panel furniture (emphasizing aesthetic surface and precise dimensions)
Automobile/Motorcycle: Chassis suspension, engine area (emphasizing anti-loosening and vibration resistance)
DIN934 (German standard) specification, which is equivalent to the national standard GB6170.
They are made of high-quality 4.8 grade carbon steel, undergo blackening / phosphating treatment on the surface, and have a uniform oil film with excellent rust prevention performance. The dimensions are precise, the mating parts operate smoothly, and the price is transparent.
