14.9 CAP
Class 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)
