This is a new high-strength fastening solution born from the joint development of top manufacturers with high technological capabilities (Yura Sangyo, Kyokuto Seisakusho, Kobe Steel).
The 14.9 hexagon socket bolt uses high-strength bolt steel with excellent "delayed fracture resistance" characteristics, boasting a tensile strength of 1,400 N/mm² while achieving over 9% elongation. Furthermore, the adoption of aerospace-grade "MJ threads" enhances the fatigue resistance of the 14.9 hexagon socket bolt. The combination of ultra strength and tightening force, along with improved thread accuracy to prevent loosening, addresses maintenance issues. The 14.9 hexagon socket bolt, treated with Delta Protect surface treatment that has passed over 1,000 hours of salt spray testing, has further long-term durability.
