The MJ Series thread form that Lawson uses on its cap screws offers improved fatigue strength over common threads. The more generous root radius puts more material at the key stress points of the threads.
• The metric equivalent of Lawson’s Tru-Torq® fasteners
• 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
