Accelerate Your Drywall Production with the Bosch GMA22 Professional Auto Feed Attachment

The Bosch GMA22 Auto Feed Attachment is a game-changing accessory designed to transform your Bosch GTB18V-45 screwgun into a high-speed, collated fastening powerhouse. Engineered for professionals who demand maximum efficiency, this attachment eliminates the tedious process of manual screw loading, allowing you to drive row after row of collated strip screws with remarkable speed and consistency. Whether you are hanging entire rooms of drywall, installing subflooring, or securing exterior sheathing, the GMA22 provides the rapid-fire capability needed to slash labor times while maintaining the surgical accuracy required for a flawless finish. Its open-housing design is a critical professional feature, actively preventing the buildup of gypsum dust and debris to ensure smooth mechanical operation and an extended tool life on even the messiest jobsites.

Precision and user comfort are at the forefront of the GMA22’s design. Weighing in at only 0.86 lbs, this lightweight composite attachment preserves the balance of your screwgun, significantly reducing wrist and arm fatigue during long overhead ceiling installations. The intuitive thumbwheel depth adjustment allows you to dial in the perfect countersink with micro-precision, ensuring every screw is set flush without tearing the drywall paper. Compatibility is nearly universal for standard strips, accommodating screw lengths from 1 inch up to 2-1/8 inches with a simple push-button selector. The work contact element provides a stable platform against the material surface, ensuring every fastener is driven perfectly straight. For contractors and drywall crews looking to dominate their production schedule, the GMA22 is the ultimate performance-boosting upgrade.

Pro-Tip: To ensure the smoothest feeding performance, always insert the screw strip from the bottom of the attachment and push it through until the first screw is just below the driving bit. If you experience any feeding resistance, a quick blast of compressed air into the open housing will clear out any fine gypsum dust that might be hindering the mechanical advance.
