Primatech Q550AL 18 Gauge Nailer


The Primatech 550A’s pneumatic fastening tools embody the most advanced technical developments in flooring installation. The 550 features the PRIMPACT module, a breakthrough for the industry.

Packed full of innovative features, the reinforced high-strength aluminum head casing offers reliability, extended performance and unequalled smoothness of operation. Close-tolerance parts assembly and a new cylinder design (for reduced wear and quick interchangeability between same generation units) are indeed a great added value for the discriminating user.

Main features of the 550AL Version

The 550AL version features a fully adjustable baseplate providing 3 distinctive advantages:


  1. Short nose and compact valve design provide an all around striking surface, enabling the nailing of more boards closer to the end walls.
  2. No shims required. The built-in adjuster eliminates the use of shims to match the board thickness.
  3. Telegraphy (Dimple Effect) control. The adjustable front block allows for ultrafine positioning, as it corrects the nail penetration to minimize or eliminate surface deformation.
