DIN912 hex socket head cap screw, also known as Allen bolt, is a highly popular standard fastener widely adopted in industrial assembly, lighting manufacturing, automation equipment and aluminum profile construction. Our factory strictly produces all screws in accordance with DIN912 international standards, selecting premium 304 and 316 stainless steel as raw materials to guarantee stable mechanical performance and long service life.
The product adopts precision rolling thread processing, with uniform thread pitch, smooth surface without burrs. It can cooperate with hexagonal wrenches for quick installation, and the cup head embedded design will not protrude after locking, effectively avoiding scratches on lamp shells, aluminum frames and equipment casings. Compared with ordinary external hex screws, DIN912 socket head cap screws occupy smaller installation space and are more suitable for narrow groove assembly of aluminum profiles, which greatly improves the overall aesthetics and structural compactness of finished products.
In terms of corrosion resistance, 304 stainless steel screws can meet daily indoor and general outdoor use, resisting moisture and mild oxidation; while 316 stainless steel models have salt spray resistance, perfectly matching coastal projects, outdoor landscape lamps and humid environment equipment assembly, effectively preventing rust and fastening failure caused by long-term exposure to rain and fog.
We supply complete specifications covering M3 to M16, with dozens of conventional lengths in spot inventory to support fast delivery for bulk orders. Besides standard sizes, we also provide customized services including special length, customized thread and special surface treatment, supporting OEM and ODM for lighting factories, machinery manufacturers and new energy enterprises all over the world.
With high tensile strength and stable locking force, this series of Allen bolts will not loosen easily under long-term vibration load, which can effectively reduce after-sales maintenance costs. If you are looking for reliable stainless steel standard fasteners for aluminum lamp frames, automation equipment and mechanical shells, DIN912 socket head cap screws will be your ideal choice.
