| Grade 14.9 high-strength hexagon socket head cap screw |
| developed by Kyokuto Seisakusho Co., Ltd., which has high technical capabilities |
| Tensile strength: 1,400Mpa |
| Guaranteed load stress: 1,120Mpa |
| High strength: Under the premise of ensuring the tensile strength of 1,400Mpa, the elongation rate of more than 9% can be achieved, and the same toughness of 10.9 grade can be achieved. |
| Anti-delayed fracture: Using KNDS4 steel from Kobelco, Japan, greatly improves the resistance to delayed fracture. |
| Fatigue resistance: [Aerospace MJ thread] is adopted to provide fatigue resistance. |
| High temperature resistance: 83% of the tensile strength can be maintained in an environment of 400 degrees. |
| Hardness: HRC44～50 |
| Dimensions: JIS B1176 (except for the lower part of the neck) |
| Screw Specification: ISO5855-1 MJ screw (for aerospace) |
| Screw accuracy: ISO5955-1, 4 g6g |
| Surface treatment: Blackening and delta-protected coat (clear 1000 hours or longer in the salt spray test) |
