16-inch Heavy-Duty Chain Wrench — Carbon Steel body with Manganese Steel Chain Key benefits Reliable strength for tough jobs: Robust carbon steel construction and a manganese-steel chain give the tool the durability needed for repeated heavy use. Wide size range: Securely grips round workpieces from 1.5 in to 7.5 in (approx. 38–190 mm) in diameter, reducing the need for multiple wrenches. Surface-safe gripping: Chain links are designed to bite in without scratching or damaging coated or delicate surfaces while still delivering a firm hold. Better control in tight conditions: Reversible (bidirectional) operation lets you switch quickly between clockwise and counterclockwise use for loosening or tightening in confined spaces. Precise torque application: Chain wrap and tool geometry provide a controlled transfer of torque for disassembly and installation tasks. Features Size: 16-inch handle for leverage and reach. Materials: Carbon steel body with high-strength manganese steel chain for longevity. Compatibility: Works on pipes, fittings and other round objects within the specified diameter range. Operation: Bidirectional design for easy switching between tightening and loosening; chain secures around the workpiece for positive engagement. Use scenarios Plumbing: Remove or tighten threaded pipes and fittings on copper, steel or PVC lines, especially when standard pipe wrenches cannot get a secure grip or when surface protection is needed. Automotive and mechanical: Hold or rotate round components such as oil filter housings or shaft collars where a non-marring grip and strong torque are required. Home maintenance and fabrication: Grip irregular or rounded parts during appliance repair, metalwork, or general maintenance without risking surface damage. Why customers choose this tool Simplifies jobs that require strong, non-marring grip on a variety of round parts. Reduces tool count by covering a broad diameter range with one durable wrench. Gives professional mechanics and DIY users a reliable, reversible option for work in tight spaces and on stubborn fittings. What to expect in use Firm, slip-resistant grip that minimizes damage to the workpiece surface. Ability to apply controlled torque for both loosening and tightening. Long service life when used within the specified diameter range and maintained according to normal workshop practice.
