- Material and construction: Made from chrome vanadium steel, these wrenches are drop-forged and hardened with integrated heat treatment and quenching. The result is strong torque, high hardness, and a thick, durable wrench body. - Ratchet mechanism: The 72-tooth ratchet gear requires only a 5-degree swivel arc, enabling use in tight spaces. This improves accuracy, saves time, and makes operation convenient. - Size and portability: Compact and easy to store and handle, these wrenches do not take up much space while providing complete specifications and easy carryability. - Metric sizing and identification: These wrenches are metric sizes and are available in many different sizes. Choose the right size for your project. Wrench sizes are stamped on both sides of the handle for easy identification. - Applications and practicality: - Bicycle maintenance and repair, such as adjusting components in tight areas like hubs or bottom brackets. - Automotive work in confined engine bays or near exhaust components where space is limited. - Furniture assembly or machinery installation where precise engagement and compact access are needed. - Performance and compatibility: High hardness and a thick body for durability and torque, combined with a precise 72-tooth ratchet and a 5-degree swing, make these wrenches dependable for metric fasteners across a range of projects.
