Introduction to Hexagonal nuts

1. What is an external hexagonal nut?

The hexagonal nut is mainly used in conjunction with bolts and screws to connect fasteners. According to the nominal thickness, they are divided into three types: type I, type II and thin. Nuts above grade 8 are divided into two types: type I and type II. Type I nuts are divided into three grades: A, B and C.

2.Application occasions of hexagonal nuts

Among them, grade A and B nuts are suitable for machines, equipment and structures with small surface roughness and high precision requirements, while grade C nuts are used for machines, equipment or structures with rough surfaces and low precision requirements. ;Type II hexagonal nuts are thicker and are mostly used in situations where assembly and disassembly are often required.
