Compatible accessories: Allen wrenches, star-shaped wrenches, socket wrenches, Phillips-head wrenches
Product Highlights: The LB series consists of all push-button screwdrivers; pressing the trigger activates the motor to begin operation, and releasing the trigger stops the operation.
Application Scenarios: The GYQ series of clutch-type constant-torque screwdrivers are not only categorized into three major series—push-down, clamping plate, and elbow-head—based on their functional use, but each series is further subdivided into more than ten models with different torque ranges to suit various industries and workstations; Low-torque models are suitable for production lines assembling smaller products such as watches, cell phones, and high-precision electronic circuit boards, while higher-torque models are suitable for larger fastening operations, such as the assembly of major home appliances, industrial assembly lines, motorcycles, and automotive interior components.
