Exceeds standard 10.9 strength characteristics by 25% for that extra margin of safety
Dimensions conform to ISO 4014 and 4017 specifications, except for increased head height for better wrenching ability
Special fatigue-resistant MJ (UNJ) thread form that meets ANSI dimensions
Fully traceable to Lawson
Property Class 12.9 1,242 MPa (180,000 PSI) minimum ultimate tensile strength
