The stanley fatmax parallel slotted screwdriver featuring a 4.0mm tip size and 100mm blade length is engineered for medium to heavy duty applications with larger fixings. This robust variant provides excellent torque transfer for demanding tasks including joinery, construction work, and general engineering applications where larger screws require firm, controlled driving. Constructed with a chrome vanadium steel bar, this screwdriver allows high torque application whilst reducing the risk of tip breakage, even under substantial load. The handle is moulded directly to the shaft for a virtually unbreakable bond, ensuring exceptional longevity in professional environments. The soft grip handle provides great control and reduces hand fatigue, whilst the smooth domed end offers fast, comfortable spinning action. The large diameter handle enables higher torque when driving wood screws, and the parallel tip design is perfect for driving screws below the material surface. Colour coding allows quick identification of this larger tip size for appropriate applications.
