Q:Does the fastener include screws?
Fastener fasteners are also known as standard parts on the market and are a generic term for a class of mechanical parts that are used when two or more parts (or components) are tightly connected as a unit. It is characterized by a wide variety of specifications, performance purposes vary, and standardization, serialization, the degree of generalization is very high. Fasteners are the most widely used mechanical base pieces and are in great demand.
Q:Are there categories of fasteners classified by material?
Mainly carbon steel, alloy steel, stainless steel, other materials category
Q:What fasteners are manufacturers in China?
