About this product
The Bosch GMA 55 is a collated screw attachment for drywall screwdrivers, designed to speed up repetitive fixing tasks such as fitting drywall panels to ceilings, including in awkward positions. Its ergonomic design and light weight of 0.36 kg help reduce fatigue during extended use.
A thumbwheel allows quick depth setting adjustment, and screw length can be changed without tools, giving flexibility across different screw sizes. It takes screws with a diameter of up to 5 mm and a maximum head diameter of 9.5 mm, in lengths from 25 to 55 mm.
The open design makes cleaning easier and helps prevent dust build-up, extending the attachment's working life. It is compatible with all Bosch Professional corded and cordless drywall screwdrivers, including the GTB 18V-45, GTB 12V-11 and GSR 18 V-EC TE.
