Zeus Drywall Screws 8x3 Z5DWSC3 3 Inch (5lb Coarse Thread Bugle Head Black Phosphate Coated Sharp Point Phillips Drive Wood Fasteners Sheetrock)

The Zeus Z5DWSC3 #8 x 3-Inch Coarse Thread Drywall Screws are heavy-duty carbon steel structural fasteners engineered for mounting thick multi-layer interior gypsum board and sheetrock panels directly to wood framing studs. Finished with a specialized friction-reducing black phosphate coating, this 5 lb bulk box delivers aggressive high-tension coarse threads optimized to maximize mechanical pull-tight grip within structural timber without stripping or structural popping over time. An ultra-sharp point ensures immediate, walk-free tracking penetration upon contact to accelerate deep framing assemblies, while the standard bugle head contours cleanly below the panel face to establish a smooth, flush indentation without tearing the protective paper liner.

Best Used For:

• Multi-Layer Panel Installation: Secures multi-layer drywall panel assemblies firmly to interior structural wood studs for enhanced fire or acoustic barriers.
• Thick Partition Structural Hanging: Attaches heavy-duty interior partitions safely to structural framing lumber, preventing premature sagging and core shifting.
• Joint Compound Finish Prep: Establishes flush countersunk anchor positions that accept drywall mud, texturing compound, and tape without blistering.

Key Performance & Safety Features

• Aggressive Coarse Pitch Threads: Specialized spacing geometry maximizes shear resistance and clamping force inside soft wood timbers.
• Black Phosphate Conversion Coating: Inorganic chemical shield provides reliable interior corrosion protection and heightens joint compound adhesion.
• Self-Piercing Sharp Point Tip: Hardened structural point punctures softwoods and engineered wood framing products instantly without pilot holes.
• Paper-Safe Bugle Head Profiling: Concave shoulder design distributes driving force evenly to seat beneath the face plane without severing paper.
• Precision #2 Phillips Drive Interface: Universal deep-set drive recess ensures constant bit engagement to prevent spinout and bit slippage.

What's Included

• (1) 5 lb. Box of Zeus #8 x 3" Coarse Thread Drywall Screws (Approx. 372 Pieces)

Technical Specifications

Pro-Tip: Set your drywall tool nosepiece depth so the bugle head compresses the paper profile slightly into a shallow recess without puncturing it; an unbroken paper face works with the deep thread anchoring to provide maximum shear values and seamless filling.
