Located in Handan, Hebei, a renowned fastener manufacturing base in China, Hebei Hengcheng Fastener Co., Ltd. (HFAST) specializes in the R&D, precision production and customized service of various high-performance industrial fasteners. 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. This innovative structural design effectively forms mechanical interference locking during installation, greatly improving friction and clamping force. It perfectly solves the common loosening problem of standard screws under long-term vibration, shock load and alternating pressure, delivering far more stable fastening performance than traditional fasteners.
Manufactured with high-grade carbon steel and stainless steel raw materials, all HFAST double thread screws undergo professional heat treatment and precise thread rolling processing. 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.
HFAST double thread screws support full-size specifications and personalized OEM/ODM customization. They are widely applicable for automotive parts, mechanical equipment, photovoltaic support systems, construction steel structures, furniture assembly and marine engineering. Benefiting from Handan’s complete industrial chain advantages, Hebei Hengcheng Fastener Co., Ltd. implements strict full-process quality inspection from raw material screening to finished product delivery.
