Product Description
Premium Grade 12.9 Retainer Bar Locking Bolt (3362261850) for Atlas Copco / Epiroc MB1200
Prevent dangerous chisel pin ejection and costly front-head damage with Toparts' heavy-duty 3362261850 retainer bar lock bolt. Specifically engineered to secure the tool retainer pin (rod pin) within the Atlas Copco / Epiroc MB1200 medium-range hydraulic hammer, this high-stress fastener is built to handle the intense physical demands of continuous rock breaking and concrete demolition.
The Toparts Engineering Difference: Built to Survive High Vibration
Standard aftermarket breaker bolts often fail due to thread fatigue caused by the fierce harmonic vibrations of the hammer. At Toparts, we manufacture the 3362261850 bolt with structural upgrades that set us apart from standard suppliers:
Class 12.9 Fatigue Resistance: Forged from vacuum-degassed alloy steel and tempered to meet strict 12.9 mechanical property standards, offering a minimum tensile strength of 1220 MPa to prevent sudden shearing.
Cold-Rolled Thread Tech: Unlike cheaply made bolts with cut threads, our threads are cold-rolled after heat treatment. This continuous steel grain structure provides 30% higher resistance to thread stripping and pulling under high impact loads.
Anti-Vibration Seating: Precision CNC-machined head dimensions ensure a perfectly flush fit into the MB1200 front head recess, shielding the bolt from flying rock debris and uneven side-loading.
Industrial Black Oxide Finish: Coated with a protective blackening treatment that resists corrosion in wet tunneling environments while acting as a dry-film lubricant to prevent thread galling during installation torque.
