Atlas Copco Drilling Rig Long Bolt 3222358797 | High-Strength Structural Fastener | OEM Part

We supply genuine Atlas Copco long bolts (Part# 3222358797), critical structural fasteners engineered for heavy-duty drilling rig assembly. Manufactured from quenched and tempered 42CrMo4 alloy steel with tensile strength of 1,200 MPa, these bolts withstand dynamic loads exceeding 25 tons in granite drilling operations. The unique anti-vibration thread design prevents loosening under 15G shock loads, ensuring structural integrity in ROC and SmartROC series rigs.

Each bolt features a zinc-nickel coating (12μm) with yellow chromate passivation, providing 1,500-hour salt spray resistance for coastal and underground mining environments. Precision-rolled threads maintain ISO 898-1 Class 12.9 tolerance (±0.02mm pitch accuracy), with magnetic particle inspection certifying zero subsurface defects. Includes pre-applied thread locking compound for permanent joint security.

Our global inventory supports same-day shipping. Orders include complimentary installation torque charts and tension monitoring guidelines for critical structural joints.
