A hexagon thin nut, also known as a hex thin nut or hexagon thin nut, is a specific type of fastener characterized by its hexagonal shape and reduced height compared to standard hex nuts. Its primary function is to provide a threaded fastening point in applications where space constraints are critical or where a lighter weight connection is desired.
Key Characteristics:
- Design: It features the standard hexagonal (six-sided) external shape for tool engagement, typically with a wrench or socket. The defining feature is its significantly lower profile or height, which distinguishes it from regular hex nuts and thick nuts.
- Standards: In China, the primary national standard governing hexagon thin nuts is GB/T 6172.1-2016, titled "Hexagon thin nuts (chamfered)." This standard specifies the dimensions, technical requirements, and marking for products with thread sizes ranging from M1.6 to M64.11 The standard is aligned with international norms and classifies nuts into Product Grades A and B.10
- Material and Performance: These nuts are manufactured from various materials including carbon steel, stainless steel (such as grades A2 and A4), copper alloys (CU2, CU3), and aluminum alloy (AL4). Performance grades for steel nuts include 04, 05, A2-025, A2-035, A4-025, and A4-035.10 Surface treatments like galvanization or passivation are commonly applied for corrosion protection.

- Applications:
- Hexagon thin nuts are widely used in machinery, equipment assembly, aerospace, and other industries where a compact, low-profile fastening solution is necessary. They are particularly suitable for situations involving thin materials or limited axial space. Specialized variants exist for demanding sectors; for example, aerospace applications may utilize "hexagonal, slotted, reduced height" nuts with MJ threads.
