Multi-function double-ended telescopic wrench designed for reliable, efficient fastening and loosening of nuts and bolts. Key benefits Secure, uniform grip: Telescopic rod with an oblique head fits closely to fasteners, clamps tightly and delivers even, strong torque for safer, more efficient work. One tool, many sizes: Adjustable telescopic length lets each end suit different nut sizes—turn the center to set the desired reach for quick on-the-job adjustments. Built to last: Critical components are carbon steel; the roller is high-hardness carbon steel resistant to damage, and the forged body undergoes 60 hours of heat treatment for high hardness, toughness, impact resistance and wear resistance. Faster, more productive work: Self-tightening action and double-sided design reduce repositioning and slipping, improving work speed and control. Features and specifications Double-sided / double-end design: Two functional ends allow use on multiple sizes without switching tools. Telescopic rod with oblique head: Close fit and consistent force distribution across the jaw for reliable torque transmission. Adjustable by center turn: Rotate the middle section to extend or retract each telescopic rod to match different fastener sizes. Materials and durability: Roller made of carbon steel; forged carbon steel body with heat treatment (60 hours) for enhanced hardness and long service life. Performance: High toughness, impact resistance and wear resistance provide durable performance in repeated use. Practical applications Home maintenance and assembly: Ideal for furniture assembly, appliance installation and routine household repairs where different nut sizes appear. Automotive and bike repair: Useful for tightening or loosening fasteners in tight spaces where a telescopic, double-ended wrench improves access and control. Light mechanical and plumbing work: Adjustable reach and self-tightening action help with fittings and connections in compact or awkward locations. What you get A durable, adjustable double-head wrench that combines telescopic reach, secure clamping, carbon steel construction and heat-treated toughness for improved efficiency and long-term reliability.
