Flange Nuts Vs Hex Nuts

Like Bolt and Screw, our factory's Hex Nut is also highly praised by customers.

Nuts are often used with Bolts and screws to connect the fastening machine. Among them, hexagon nuts are the most widely used.

Function of hexagonal nuts: Hexagonal nuts are used in conjunction with bolts and screws to connect and fasten parts.

According to the nominal thickness, hex nuts are divided into three types: type I, type II and thin type. Nuts above grade 8 are divided into two types: type 1 and type II.
Type I hexagonal nuts are the most widely used. Type 1 nuts are divided into three grades: A, B and C. Among them, grade A and grade B nuts are suitable for machines, equipment and structures with small surface roughness and high precision requirements. C-level nuts are used for machines, equipment or structures with rough surfaces and low precision requirements; type 2 hex nuts are thicker and are often used in occasions that often need to be assembled and disassembled.
Type 1 nuts refer to ordinary hexagonal nuts with a nominal nut height m≥0.8D, and their type and size should meet the requirements of GB/T6170;
The height of the type 2 nut is higher than that of the type 1 nut, and its type and size should comply with GB/T6175. The purpose of adding type 2 nuts is twofold: one is to obtain a relatively cheap nut that does not require heat treatment by increasing the height of the nut.
Because D≤M16 grade 8 type 1 nuts do not need heat treatment, so among the 8 grade nuts, only the specifications of D>M16~39 use type 2 nuts.
Obviously, Type 1 nuts without heat treatment cannot meet the mechanical performance requirements of Type 9 nuts. Another purpose of specifying Type 2 nuts is to obtain tougher Grade 12 nuts. As the height of the nut increases, the guaranteed stress index can be achieved at a lower quenching and tempering hardness, so the toughness of the nut is increased.
