Rigging Hardware
Features
- Forged steel — quenched and tempered.
- Working load limits shown are for an in‑line pull.
- Fatigue rated at 1‑1/2 times the working load limit at 20,000 cycles.
- 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.
