These fixed anchor bolts are used to create a secure fastening point in construction and industrial assemblies. The bolt structure is suitable for connecting building components, equipment bases, steel frames, support brackets, machinery parts, and other fixed installation systems. When matched with suitable nuts and washers, the anchor bolt helps improve installation stability and fastening reliability.
The product supports both steel and stainless steel options. Q235 and 35K are practical material choices for general construction fastening, hardware distribution, equipment assembly, and cost-effective industrial use. A2-70 stainless steel provides good corrosion resistance for exposed or humid environments, while A4-80 stainless steel offers higher stainless steel strength and better resistance for more demanding conditions.
For strength grade selection, Grade 4.8 is suitable for general-duty fastening and light to medium installation work. Grade 8.8 is suitable for stronger mechanical fastening requirements. A2-70 and A4-80 are stainless steel strength grades commonly selected when corrosion resistance and stable mechanical performance are both required.
The product can be supplied with surface treatment options including Zinc, Plain, and Plain Zinc. Common thread sizes include M6, M8, M10, and M12, while the model range covers M6-M16 and customized sizes can support M3-M30 according to order requirements.
