Stanley 21A108700 Nutrunner Torque Controller

Stanley 21A108700 Alpha Series Nutrunner Torque Controller is a dedicated control module designed to govern torque when paired with Stanley Assembly Technologies' Alpha Series nutrunners on automated fastening lines. The unit is powered from standard mains, supporting 115/230 VAC at 50/60 Hz, and it draws up to 10 A, making it compatible with common industrial power circuits. As a torque controller, it enables repeatable tightening cycles by stabilizing torque during tightening, helping ensure consistent joint quality and reducing over- or under-torque events. The 21A108700 model is identified as part of Stanley's Alpha Series lineup and is intended to work with compatible Stanley nutrunners in configured assembly cells. This specific product has been discontinued by the manufacturer, so availability may be limited to distributors and surplus channels. For buyers, the key considerations are confirming compatibility with your existing Stanley tool controllers and the Alpha Series torque units in your line configuration, as well as ensuring your power infrastructure matches the 115/230 VAC, 50/60 Hz requirements.
