Q: Bolts and other connection fasteners some points A B C grade what it means: The same standard number! Different grades of bolts, their material is not the same! Just their detection method just the same!

Q: Fasteners often say that the nature of galvanized oxidation is what it means: Fasteners, is a fastening connection with the application of a very wide range of mechanical parts. Fasting, widely used in industries such as energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic, etc., in various machinery, equipment, vehicles, ships, railways, bridges, construction, structure, tools , Chemical, instrumentation and supplies, etc., can see a wide range of fasteners, is the most widely used mechanical base pieces. It is characterized by a wide variety of specifications, performance purposes vary, and standardization, serialization, the degree of generalization is also very high. Therefore, some people have a national standard of a class of fasteners called standard fasteners, or simply referred to as standard parts.
