S-91608A329 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in humid or outdoor wood applications.
• Enhanced pull-out resistance through the thread forming tapping method, creating strong, permanent threads in wood without pre-tapping.
• Clean, flush finish with the standard oval head and 82° countersink angle, providing a smooth, professional appearance in finished woodwork.
• Optimized for different wood types with specified drill bit sizes (9/64" for hardwood, 7/64" for softwood), preventing splitting and ensuring precise installation.
• Reliable driving control via the slotted drive design, allowing for secure tool engagement and reduced cam-out risk during installation.
• Secure fastening in end-grain or thin materials due to the partially threaded shank, which concentrates holding power where it's needed most.
• Environmental and regulatory safety with full compliance to RoHS 3 and REACH standards, making them suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

These No. 14 wood screws are precision-engineered to address common challenges in woodworking and carpentry applications. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, which is critical for outdoor furniture, decking, and marine environments where moisture exposure is a concern. The partially threaded design ensures that the screw’s grip is maximized in the top piece of wood, reducing the risk of loosening in end-grain or when joining materials of varying densities. Combined with the thread forming method, these screws eliminate the need for separate tapping operations, saving time and labor in high-volume production. The oval head with slotted drive offers a traditional, aesthetically pleasing finish that sits flush with the surface, making it ideal for visible applications in cabinetry, millwork, and architectural woodwork where both strength and appearance matter.
