The MA 55 attachment is compatible with Bosch professional screw guns GSR 6-25 TE, GSR 6-45 TE, GSR 18V-EC TE and GSR 10.8V-EC TE. Assembly, dismounting and adjustment are all tool-free operations, greatly simplifying its use. The MA 55 takes commercially available collated screws. The use of collated screws increases production and accuracy. This attachment can handle screws 25mm to 55mm long with a maximum shank diameter 5mm and maximum screw head diameter of 9.5mm (dependent on the main machine’s capacities). The MA 55 offers comfortable and continuous working due to its ergonomic design and low weight. The open design ensures a long working life as it helps prevents dust deposits in the attachment.
