As one of our star engineered products, HFAST double thread screws stand out in the global market for their unique dual-thread structure, superior anti-loosening performance and high assembly efficiency, serving as an ideal fastening solution for high-precision and high-vibration engineering scenarios.
Different from conventional single-thread screws, HFAST double thread screws adopt an optimized dual-thread design with matched lead angles.

The threads feature uniform tooth shape, high hardness, strong tensile strength and excellent wear resistance. Equipped with premium galvanized or passivated surface treatment, the products boast outstanding rust-proof and corrosion-resistant capabilities, adapting to harsh working environments including outdoor exposure, coastal salt fog, high humidity and frequent mechanical vibration.
