Makita Pneumatic Crown Stapler AT1150A 7/16 Inch Medium 16 Gauge Air Gun (120 PSI 3.7 SCFM Sheathing Subflooring Woodworking Framing Kit Case)

High Capacity Heavy Duty Fastening for Structural Sheathing and Subflooring

The Makita AT1150A 16-Gauge 7/16" Medium Crown Stapler is a pneumatic structural construction tool engineered to drive medium crown staples with leg lengths from 1 inch to 2 inches. Operating within a compressed air pressure range of 65 to 120 PSI, this air-powered hand tool provides consistent driving force for high-volume sheathing, framing, and pallet production environments. The lightweight 5.1-pound design integrates a top-loading aluminum magazine, a tool-less depth adjustment system, and a quick-release cam-lock nose to optimize mechanical output and maintain job-site efficiency.

Best Used For:

• Structural Wall Sheathing: Fastening plywood or OSB panels directly to exterior framing members with code-compliant structural holding power.
• Subflooring Installation: Securing subfloor panels rapidly to floor joists to eliminate floor squeaks and assure a stable underlying deck.
• High-Volume Crating: Assembling heavy-duty commercial wooden shipping crates, pallets, and industrial storage packaging containers.

Key Performance & Safety Features

• Top-Loading Aluminum Magazine: Holds up to 140 staples for minimal reloading downtime during long structural fastening runs.
• Tool-Less Depth Control: Tactile micro-adjustment dial enables fast changes between perfectly flush seating and clean countersunk driving.
• Cam-Lock Jam Clearance: Quick-release nose assembly pops open without extra tools to facilitate instant removal of jammed fasteners.
• Inlet Filter Integration: Built-in internal air filter traps ambient dust and compressor moisture to extend inner cylinder motor life.
• 360-Degree Multi Exhaust: Rotating exhaust deflector allows the operator to direct spent compressed air paths entirely away from their face.

Technical Specifications

Pro-Tip: Check your line pressure dynamically by firing a test staple into scrap workpiece material; if the crown sits proud, adjust your compressor regulator upward rather than just driving the tool harder, as this avoids uneven cylinder fatigue.
