Fixed Bolt C190001118 is a critical high-strength fastener for Hydraulic Rock Drills. It performs reliably in harsh mining environments—underground mines, open-pit quarries and heavy construction sites.
As a key fixation component, Fixed Bolt C190001118 secures core structural parts tightly. It solves industry pain points: bolt loosening under high-frequency vibration, insufficient tensile strength and corrosion damage in humid mine conditions.
We craft this fixed bolt with premium 40CrNiMoA alloy steel. We temper it to reach 10.9-grade strength, enabling it to withstand 900MPa tensile force without deformation or breakage.
It features anti-loosening precision threads (tolerance ±0.01mm) that lock tightly with nuts. No thread slippage occurs even during long-term high-vibration drilling operations.
The surface undergoes hot-dip galvanization treatment. It endures 96-hour salt spray tests, withstanding mining humidity and abrasive debris without rusting.
Our quality team conducts strict ISO 9001 verification for each unit. We perform tensile strength tests, 30,000-cycle vibration trials and thread accuracy checks.
Fixed Bolt C190001118 fits Atlas Copco FlexiROC T90, Sandvik DP2900 and generic Hydraulic Rock Drill brands. A torque-controlled installation sim plifies fitting—no custom modifications required.
Backed by a 12-month warranty, it’s a cost-effective investment for mining firms. It reduces equipment structural failure rate by 55% and cuts maintenance downtime. It guarantees stable, efficient operation of Hydraulic Rock Drill systems.
