The Everwin SN50S4 is engineered for demanding fastening applications where a medium wide-crown staple offers excellent hold and durability. With its sturdy build, optimized driving power and medium-crown design, this tool serves well in pallet construction, crate building, sub-frame assembly, and other mid-to-heavy duty fastening environments.
Key Features

-
Durable yet ergonomic body, designed for reduced fatigue and quicker cycle performance
-
Adjustable driving depth to match material conditions and ensure consistent clinch
-
Bottom or side loading magazine (depending on version) for rapid reloads and minimal downtime

Why Choose This Tool?
-
Offers a smart balance between standard wide-crown heavies and ultra-wide industrial models — ideal when you need strong hold but don’t require the largest-crown frames.
-
Built for production durability and streamlined use, delivering reliable results in manufacturing, packaging, construction, and sub-assembly environments.
-
Medium-crown staples provide broad-footprint anchoring without massive crown overhead, making them versatile across layered and dense substrates.
Things to Know Before Buying
-
Requires a clean, regulated air supply capable of delivering the specified operating pressure (70-100 psi); inadequate air system affects staple penetration and clinch.
-
Ensure your fastener inventory matches the crown width (⅝″) and leg length range of the tool — using incorrect staples risks poor hold or tool damage.
-
Even though the tool is optimized for productivity, frequent or overhead use still benefits from ergonomic attention and operator breaks.
-
If your application involves extremely dense stacks, heavy structural materials, or very large fastener leg lengths, double-check that the SN50S4’s spec aligns with your needs — a larger-crown or heavier-duty model may be more appropriate.
