Adjustable double-head wrench — self-clamping, telescopic design, fits 7–19 mm Key benefits One tool for many sizes: the adjustable, double-head design replaces multiple fixed wrenches by covering nuts and bolts from 7 mm to 19 mm. Secure grip and consistent torque: the angled head and self-clamping mechanism hold fast without slipping, giving even, strong torque for safer, faster work. Built to last: engineered with high hardness and corrosion-resistant construction to withstand repeated use and remain reliable for household and light mechanical tasks. Improved efficiency: telescopic bar design increases accessibility and leverage so you can work in tighter spaces and complete tasks quicker. Main features Adjustable range: handles nut/bolt diameters from 7 mm to 19 mm. Double-head / double-sided tool: two working ends for flexible use and easier handling. Telescopic bar with angled head: close fit to fasteners, better clearance, and improved leverage. Self-clamping (self-tightening) adjustable jaw: reduces slipping and minimizes fastener damage. High hardness and corrosion resistance: durable finish and materials for long service life. Even torque distribution: designed to apply force uniformly for safer tightening and loosening. Typical applications Home repairs and furniture assembly: ideal for door hardware, cabinet bolts, and assembling flat-pack furniture. Bicycle and small engine maintenance: works on axles, brake adjustments, and small engine fasteners in limited spaces. Plumbing fixtures and light mechanical tasks: useful for tightening or removing nuts on fittings and household appliances. Performance notes Best suited for household and light mechanical use where a compact, versatile, and durable adjustable wrench is needed. Select the correct jaw opening for the fastener, ensure the angled head seats squarely, and apply steady force for optimal grip and torque.
