Drywall Screw

A drywall screw is a hardened screw with a bugle-style head and thread selected for gypsum board fastening. It fastens gypsum board to metal studs or timber framing, depending on thread and point design. Buyers should specify substrate, coarse or fine thread, diameter, length, head recess, point, corrosion finish and packaging. Standards listed here govern particular forms and do not make sizes, materials or finishes interchangeable. The RFQ should state the exact standard or drawing, required configuration, quantity and inspection evidence. This directory entry is a neutral reference for procurement and verification. It does not imply that any product or supplier is certified or compliant with the listed standard. Always confirm model-specific values and standards with the legal manufacturer or supplier before purchase. The product is a component used in fabricated metal product manufacturing, specifically for attaching gypsum boards to framing. The working principle involves the sharp point starting the hole, the thread engaging the framing material, and the bugle head seating without tearing the board face when correctly driven. Key parameters include applicable standard (EN 14566), nominal size/range (supplier series; specify diameter, length and framing material), material (hardened carbon steel), strength/performance (driving, penetration and head-pull-through evidence by application), surface finish (black phosphate, zinc-plated or specified corrosion finish), and RFQ selection fields (substrate, coarse or fine thread, diameter, length, head recess, point, corrosion finish and packaging). These parameters must be confirmed against the selected standard, drawing and supplier evidence. The product is not a complete system; it requires proper selection and installation. Maintenance signals include corrosion or loosening, and failure boundaries include improper thread engagement or head pull-through. Verification questions should address the exact standard, configuration, and inspection evidence.

The sharp point starts the hole, the thread engages the framing material and the bugle head seats without tearing the board face when correctly driven. The screw is designed for gypsum board fastening to metal or timber framing. The thread type (coarse or fine) is selected based on the substrate. The bugle head provides a countersunk finish that reduces board damage. Correct driving depth is critical to avoid tearing the paper face. The screw is made of hardened carbon steel for strength. The working principle relies on the interaction of point, thread, and head geometry. The screw must be driven straight to ensure proper engagement. Overdriving can cause the head to break through the board. Underdriving leaves the head protruding. The screw's performance is verified through driving, penetration, and head-pull-through tests as per the application standard. The user must select the appropriate screw for the specific framing material and board thickness.
