Technical Description and Application<\/h2>\n

The international standard regulates the geometric parameters and manufacturing quality requirements for low hexagon nuts (product grade 0) without chamfer. The nomenclature covers a range of metric threads from M1.6 to M10, corresponding to product grade B. These fasteners are designed for use in high-precision assembly units where a minimal profile height is critical.<\/p>\n

For cases not covered by this regulation, or if specific tolerances are required, reference should be made to ISO 965-1, ISO 4759-1, and relevant international specifications.<\/p>\n

Geometric Parameters<\/h3>\n

The size nomenclature and letter designations correspond to the ISO 225 specification. All linear dimensions are in millimeters.<\/p>\n
