The Simpson Strong-Tie XLSH78B1414-RP83 Large Shouldered Screw is built for high-strength steel-to-steel fastening, delivering consistent performance and reliability in structural framing applications. Designed with a large bearing surface and robust shouldered shank, these screws provide strong clamping force and shear capacity in light-gauge steel framing and panelized construction.

Each screw features a self-drilling point that eliminates the need for predrilling, saving time during installation. The large shoulder under the head helps resist pull-through, making these fasteners an ideal choice for attaching steel components such as clips, straps, or cold-formed framing elements. Available in multiple sizes and quantities to meet the needs of both professionals and commercial contractors.

Key Features:

• Shouldered design enhances bearing surface and pull-through resistance
• Self-drilling tip eliminates predrilling in light-gauge steel
• Optimized for shear and tensile strength in structural applications
• Carbon steel construction with black phosphate coating for corrosion resistance in dry environments
• Precision-manufactured for consistent drive and alignment

Applications:

• Cold-formed steel framing
• Structural panel attachments
• Clips, straps, and framing hardware connections
• Light-to-medium gauge steel assemblies
• Commercial construction and prefabricated framing systems

Installation Notes:

• Designed for use with light-gauge steel
• No predrilling required in most applications
• Use with a compatible driver bit for clean, flush installation
• Install until shoulder seats against the surface; do not overtighten
