Type 2 hexagonal flange nut GB/T 6177.1 is a common fastener that is widely used in various fields such as machinery, construction, and transportation. This type of nut no longer requires the use of spring washers, and is used with bolts (studs or screws) with external threads to fasten two connected parts (parts, components, etc.) using internal and external thread connections. During assembly and disassembly, use a wrench to hold the nut to prevent it from slipping, but please note that you can only use an adjustable wrench, a dead wrench, a dual-purpose (open part) or a special square hole socket wrench for assembly and disassembly.
Type 2 hexagonal flange nut GB/T 6177.1 provides a variety of specifications to choose from, such as M5, M6, M8, M10, M12 (M14), M16 and M20, etc. The sizes in brackets are non-preferred sizes.
The GB/T 6177.1 standard for type 2 hexagonal flange nuts specifies the size, shape, marking and material requirements of the nuts in detail to ensure that they comply with national standards.
