• Forged steel - Quenched & Tempered.
• Working Load Limits shown are for in-line pull. For angle loading,
see Warnings & Applications.
• Fatigue rated at 1-1/2 times the Working Load Limit at 20,000
• Recommended for in-line pull.
• S-279 threaded UNC.
• M-279 metric threaded.
• Meets or exceeds all requirements of ASME B30.26 including
identification, ductility, design factor, proof load and temperature
requirements. Importantly, these bolts meet other critical
performance requirements including fatigue life, impact properties
and material traceability, not addressed by ASME B30.26.
