Industrial 21A108700 Nutrunner Drive Controller

Stanley Assembly Technologies 21A108700 Nutrunner Drive Controller is a torque controller used to govern the torque output of Stanley nutrunner systems in automated fastening cells. The unit is specified for 10 A and accepts 115/230 VAC input, enabling compatibility with common industrial power distributions, and it weighs 16.75 lb, reflecting its rugged factory-floor enclosure. Market listings describe the model as a Nutrunner Torque Controller rather than a generic servo drive, underscoring its role in delivering precise torque profiles during fastener installation to ensure repeatable joint quality. The 21A108700 is listed as discontinued by the manufacturer in repair and surplus catalogs, and it appears in variants referenced as 21A108700 Part B and Part C in repair listings, reflecting the model’s legacy status in spare parts ecosystems. Beyond new-in-box availability, the product is frequently encountered in refurbished or repairable form from independent suppliers and marketplaces, indicating ongoing demand for existing units in service environments that rely on Stanley nutrunner tools for consistent performance. In practice, this controller supports torque control for Stanley nutrunner operations, aligning tool output with defined torque profiles to help maintain process accuracy and repeatability in automotive, electronics, and industrial assembly applications where Stanley Assembly Technologies equipment is deployed.
