With a length of 25 mm and a 3.6 mm diameter, they feature a fine thread and a black phosphated finish that helps protect the material during installation. Each pack contains 1000 pieces held together on a flat paper strip, which allows for rapid, sequential driving without the need to load screws individually.

They work seamlessly with Hikoki and Hitachi models such as the W4YD, W4YE, W4YF, WF4DSL, WF4DY, WF14DSL, and WF18DSL, and are also suitable for use with equipment from Hilti, Fein, Makita, Max, Powers, Poppers/Senco, Spero, and Würth.
