Aluminum and copper flat washers, what are the specifications and models of flat washers + stamping accuracy up to 0.01mm

Xiaoshuo, who is responsible for the hardware manufacturing of aluminum and copper flat washers, organizes the specification, model and size table of flat washers for everyone, and collects them in speed. Flat washers can be divided into small series, standard series, large series and extra large series according to the structure. According to product accuracy, it can be divided into A-level and C-level. Therefore, the specifications and model tables of flat washers also need to be divided into corresponding tables according to different series and accuracy.　　1, flat washers class C (GB/T 95-2002) 　　 class C washers are used with class C bolts and nuts. Flat washer C-level size 2, large washer A (GB/T 95.1-2002) and large washer C (GB/T 96.2-2002) 　　 Large washer means that the outer diameter d2 and thickness h are larger than ordinary washers. Mainly used in the connection of non-ferrous metal parts such as wood or aluminum. Class A large washers are used with Class A or appropriate precision bolts and nuts. Large washers Class A size Large washers Class C size 3, Flat washers Class A (GB/T 97.1-2002), Flat washers chamfered Class A (GB/T 97.2-2002) and flat washers for pin shafts (GB/T 97.3-2000) 　　 These three washers protect the connected surface and reduce the surface pressure of the bolt head on the connected part. This kind of products are all grade A, GB/T 97.1 is not chamfered, mainly used for M1.6~M36 grade A and B bolts, screws, nuts, GB/T 97.2 is chamfered, mainly used M5~M36A is matched with grade B bolts, screws and nuts. Flat washer class A size (GB/T 97.1-2002) 　　 flat washer chamfered type A size (GB/T 97.2) 　　 pin washer size (GB/T 97.3-2000) 　　4, small washer A class (GB/ T 848-2002) 　　 Class A small series of flat washers are mainly used for screws with cylindrical heads with thread specifications from M1.6 to M36. Hardware, 15 years of focus on aluminum and copper flat washers, 5,000 square meters production workshop, hundreds of precision processing production equipment, 20,000+ sets of flat washer mold customized production experience, more than 20 Ru0026D design engineers, flat washers stamping accuracy can reach 0.01mm, The precision of flat washers can reach 0.01mm, and 16 quality inspections strictly control the quality from raw materials layer by layer. Can quickly solve the problem of time, accuracy and quality for you!
