For demanding wood construction and joinery, selecting the right fastener is critical. Type 17 screws are engineered specifically for wood, offering a combination of efficiency and holding power that makes them a standard in professional carpentry, furniture manufacturing, and timber framing.
Technical Design & Core Features
Type 17 screws are distinguished by a sharp, self-drilling point combined with a unique auger-style thread. This continuous helical thread design enables rapid, effortless penetration into timber, often eliminating the need for pre-drilling pilot holes. The deep, sharp threads are engineered to maximise pull-out resistance and minimise the risk of wood splitting by gradually displacing fibres.
Primary Applications
These screws are versatile for a wide range of wood-to-wood fastening applications, including:
Structural timber framing
Decking and outdoor structures
Furniture and cabinetry assembly
General joinery and construction with softwoods, hardwoods, and engineered wood products.
Key Advantages for Professional Use
Installation Efficiency: The self-drilling tip significantly reduces assembly time and labour costs by removing the pre-drilling step.
Superior Holding Power: The deep auger thread provides exceptional grip and resistance to withdrawal, ensuring long-term joint integrity.
Reduced Wood Splitting: The design minimises stress on the material, making them suitable for use near edges or with delicate timbers.
Finishing Options: Available with countersunk (flat or bugle) heads for a flush finish, and in various corrosion-resistant materials (e.g., stainless steel, zinc-plated) for interior or exterior use.
Selection and Installation Guidance
Material Selection: Choose stainless steel or suitably coated screws for outdoor or high-moisture environments to ensure longevity.
Installation Best Practice: Use a compatible driver bit and apply steady, appropriate torque. For very hard or dense woods, a pilot hole may still be recommended to prevent driver strain or splitting.
Conclusion
Type 17 screws provide a reliable, high-performance fastening solution for professional woodworking. Their engineered design addresses common challenges such as splitting and installation speed, making them a practical choice for projects requiring strength, efficiency, and a clean finish. Tianyu supplies a range of Type 17 screws in various sizes and finishes to meet specific project requirements.
