S-91606A113 Length 3/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for long-term use in humid or outdoor wood applications.
• Flush, professional finish thanks to the standard 82° flat head profile and slotted drive, ensuring countersunk installation without protrusion.
• Enhanced holding power from thread forming technology, which compresses wood fibers for a tighter, more secure grip without pre-tapping.
• Optimized for wood materials with pointed tip and partial threading, reducing splitting and enabling faster, cleaner insertion.
• Precision installation guidance with recommended drill bit sizes (1/16" for hardwood, 3/64" for softwood) to prevent misalignment and ensure optimal thread engagement.
• Reliable right-hand threading and 22 threads per inch design, providing consistent driving performance and ease of use with standard tools.
• Environmentally responsible compliance meeting RoHS 3 and REACH standards, ensuring safe, sustainable use in regulated industries.

Professional Applications & Engineering Value

These No. 4 x 3/4" flat head slotted wood screws are engineered to address common challenges in woodworking and assembly, such as material splitting, corrosion, and inconsistent fastening. The 18-8 stainless steel material offers excellent resistance to rust and oxidation, making these screws suitable for both indoor furniture and outdoor structures exposed to moisture. The thread forming design eliminates the need for separate tapping by displacing wood fibers, which enhances pull-out resistance and minimizes the risk of stripping. With a standard 82° countersink angle and slotted drive, these screws sit flush with the surface, providing a clean aesthetic while maintaining structural integrity. Ideal for applications in cabinetry, joinery, and decorative wood projects, they ensure reliable performance in hardwood and softwood with pre-specified drill sizes to streamline installation and reduce errors.
