Introduction
Overview of the standards for MJ threaded aluminum alloy through-hole self-locking inserts for aviation
MJ threaded aluminum alloy through-hole self-locking inserts for aviation are fasteners specifically used in the aerospace field, and their design and manufacturing must meet strict technical standards. This standard (GB/T 36224-2018) specifies in detail the structure, dimensions and technical requirements of such parts.
Background of standard formulation and analysis of technological evolution
With the development of the aerospace industry, the requirements for fasteners are increasing. This standard is formulated based on existing technical specifications and aims to unify the technical requirements for MJ threaded aluminum alloy inserts in the aviation field and improve product quality and reliability. Its technological evolution is mainly reflected in the optimization of material selection, surface treatment and thread design.
Structure and size requirements
| Diameter specification | MJ thread parameters | d1 tolerance range | D tolerance range | L tolerance range | H1 value | d2 tolerance range |
|---|---|---|---|---|---|---|
| 030 | MJ3X0.5-4H6H | 7~30 | 14.2 | 9.3 | 3 | 2.4 |
| 040 | MJ4X0.7-4H6H | 8~40 | 14.2 | 9.3 | 4 | 2.4 |
| 050 | MJ5X0.8-4H6H | 10~50 | 17.5 | 11.9 | 5 | 2.4 |
Material and surface treatment requirements
The standard clearly stipulates that the material of the inlay must be 2024 aluminum alloy that meets the EN3347 specification and must be anodized (ISO8076). This treatment not only improves the corrosion resistance of the material, but also enhances its stability in high temperature environments.
Implementation recommendations
To ensure the effective implementation of the standard, it is recommended that:
- Strictly follow the tolerance requirements for production and inspection
- Use advanced testing equipment to verify thread parameters
- Strengthen supplier management to ensure material consistency
