Truss head drywall screws are specialized fasteners distinguished by their low-profile, wide-domed head design, engineered for securing gypsum drywall panels and other lightweight building materials in applications where a flush or semi-flush finish is not required, but stable clamping force and surface protection are priorities. Unlike the countersunk bugle head (standard for drywall), the truss head’s broad bearing surface distributes pressure evenly, preventing material damage and making it ideal for exposed or semi-exposed installations.
Key Features
Truss Head ProfileThe head has a wide, flat top with a rounded, low-profile shoulder—wider than bugle heads but thinner than pan heads. This design:
Distributes clamping force over a larger area, avoiding indentation or cracking of drywall, plywood, or fiber cement boards.
Eliminates the need for countersinking, simplifying installation for quick repairs or temporary bracing.
Provides a visible, neat finish for exposed applications (e.g., basement framing, utility room partitions).
Compatible with Phillips, square (Robertson), or Torx drives—Torx drives are preferred for high-torque use to prevent cam-out.
Thread Design VariationsTruss head drywall screws are available in two thread types to match framing substrates:
Coarse thread: For fastening drywall to wood studs, joists, or furring strips—wide thread pitch enables fast penetration and strong grip in softwood/hardwood.
Fine thread: For securing drywall to light-gauge steel framing—dense threads lock into metal without stripping, suitable for 20–25 gauge steel studs.
Material & Corrosion Resistance
Core material: High-carbon hardened steel (C1018–C1022) for superior tensile strength, resisting bending or breaking during installation.
Coatings:
Phosphate coating: For temporary rust protection during construction, ideal for indoor dry environments.
Electro-galvanized zinc: For general indoor use, providing moderate corrosion resistance.
Hot-dipped galvanized (HDG) or stainless steel (304/316): For humid, outdoor-adjacent, or corrosive environments (e.g., garages, coastal areas).
Standard Size Specifications
Diameters: #6, #8 (most common for drywall; #10 for heavy-duty applications like attaching thick cement boards).
Lengths: 1 inch (25 mm) to 3-1/2 inches (89 mm)—length selection depends on material thickness, with a minimum of ⅝ inch thread engagement in framing required for stability.Core Advantages
Surface Protection: Wide head prevents damage to brittle materials (drywall, fiberboard) that can occur with narrow bugle heads.
Easy Installation: No countersinking needed, cutting down labor time for fast repairs or temporary framing.
Versatile Compatibility: Works with both wood and metal framing, adapting to mixed construction projects.
Visible Fastening: Clean, uniform head appearance for semi-exposed areas where aesthetics matter (no need for joint compound concealment).
