A hexagonal nut with a higher height than a common nut.
china Thin hexagon nut is used together with bolts and screws,for connecting and fastening parts.
Based on the different nominal thickness ,Hexagon nuts include type1,type2 and thin type.
Type 1 is used most widely ,includes grA,grB,grC.grA and grB are suitable for the machinery,equipment and structures,which with the small roughness of surface and high accuracy requirement.and the GrC is less demanded than GrA and GrB about the roughness and the accuracy requirement.
Type 2 hexagon nut is thicker than type1,its mostly used in the case where is often needed assembly and disassembly.
The type and size of Type1 should meet GB/T6170.And Type2 should meet GB/T1670.
