304/316 Stainless Steel Pan head half thread phillips drive wood screw
Stainless steel 304 and 316
StainGrip® 304 & 316 Stainless Steel Pan Head Partial Thread Phillips Drive Wood Screws are high-strength timber fasteners engineered for maximum clamping force and superior joint tightness in woodworking, cabinetry, outdoor furniture, and marine timber applications. Manufactured from premium SS304 and marine-grade SS316 stainless steel, these screws offer outstanding resistance to rust, outdoor weathering, and harsh chemical wood treatments, while the partial thread design prevents board separation and jack-up during installation.
Key Features & Technical Benefits
Premium SS304 & SS316 Stainless Steel (Maximum Corrosion Resistance): Formulated with high nickel and chromium content (plus molybdenum in SS316) to provide ultimate long-term protection against rust, outdoor moisture, weathering, and saltwater environments.
Partial Thread / Smooth Shank Design (Anti-Jacking Clamping Power): The unthreaded upper shank allows the top wooden board to slide freely and pull tightly against the underlying timber, completely eliminating gaps and board jacking for an ultra-tight joint.
Rounded Pan Head Design (Broad Clamping Surface): Features a broad pan head with a flat bearing surface underneath, distributing clamping force evenly across timber surfaces or metal brackets without crushing soft wood fibers or requiring a countersunk recess.
Precision Phillips Drive System (Universal Compatibility): Deep-cut Phillips cross recess ensures optimal driver bit engagement, reducing driver slippage and allowing seamless installation using standard power tools or manual screwdrivers.
Sharp Gimlet Point & Deep Coarse Wood Threads: Equipped with a razor-sharp tip for quick bite and aggressive coarse threads that carve tightly into wood fibers, delivering high pull-out strength in hardwoods, softwoods, and engineered timber.
