Tension Bolt C190001077 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, Tension Bolt C190001077 secures core drill parts tightly. It solves industry pain points: bolt loosening under high vibration, insufficient tensile strength and corrosion damage in humid conditions.
We craft this tension bolt with premium 40CrNiMoA alloy steel. We temper it to reach 12.9-grade strength, enabling it to withstand 1200MPa tensile force without deformation.
It features precision-rolled threads (tolerance ±0.01mm) that ensure tight mating with nuts. An anti-loosening design prevents thread slippage during long-term drilling operations.
The surface undergoes galvanization and anti-corrosion coating. It endures 96-hour salt spray tests, withstanding mining humidity and abrasive debris.
Our quality team conducts strict ISO 9001 verification for each unit. We perform tensile strength tests, 20,000-cycle vibration trials and thread accuracy checks.
Tension Bolt C190001077 fits Atlas Copco FlexiROC T70, Sandvik DP2500 and generic Hydraulic Rock Drill brands. A torque-controlled installation simplifies fitting—no custom modifications required.
Backed by a 12-month warranty, it’s a cost-effective investment for mining firms. It extends equipment service life by 45% and reduces maintenance downtime. It guarantees stable, efficient operation of Hydraulic Rock Drill systems.
