It is compatible with electric wrenches, ratchet wrenches, and manual wrenches, meeting various work requirements.
• •PREMIUM MATERIAL & PHOSPHATING COATING: The 3/8-inch impact swivel socket set is made of impact-grade chrome molybdenum steel (CR-MO), featuring high hardness and strength. Socket surfaces are treated with a black phosphating coating and paired with anti-rust oil, which enhances corrosion resistance and high-temperature resistance, and extends the product's service life.
• •360° UNIVERSAL DESIGN & SPHERICAL STRUCTURE：The wobble socket set features a 360° universal joint at its core, with a maximum lateral deviation/tilt angle of 60°, facilitating access to tight spaces and easily reaching hard-to-reach fasteners. Its internal spherical structure stably transmits force, extending the service life.
• •6-POINT DESIGN & SIZE MARKING: Adopting a 6-point side drive design, prevents fastener rounding caused by high torque output and ensures the socket itself maintains its shape. Meanwhile, each socket is marked with sizes via laser engraving and stamping. The set also comes with a storage case, facilitating long-term identification and organized storage.
• •AFTER-SALES SERVICE: All BLACKROBOT sockets undergo rigorous testing to ensure excellent performance and durability. BLACKROBOT tools meet or exceed ANSI and DIN performance standards and provide a one-year warranty. If any socket is damaged, you can contact us at any time.
