S-90000A300 Length 4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for humid or chemically aggressive environments
• Enhanced torque transfer and reduced cam-out thanks to the square drive design for secure, efficient installation
• Easier installation in dense materials with thread-cutting (Type 17) technology that taps its own mating threads
• Reliable, flush-mount fastening provided by the standard flat head profile for a clean, finished appearance
• Exceptional holding power in wood and composites due to the 0.216" thread diameter and 11 threads per inch
• Long-lasting structural integrity with a substantial 4" length and partially threaded shank for optimal grip
• Compliance with major environmental regulations, including RoHS 3 and REACH, ensuring safe and responsible usage

Professional Applications & Engineering Value

These 316 stainless steel wood screws are engineered to solve critical fastening challenges in demanding applications like outdoor construction, marine environments, and high-moisture areas where corrosion resistance is paramount. The thread-cutting (Type 17) point and square drive work in tandem to eliminate the need for pre-drilling in many wood and plastic-wood composite materials, significantly speeding up assembly while preventing material splitting. This combination delivers a robust, reliable connection that withstands vibrational forces and environmental stress, maximizing the service life of decks, fencing, and structural frameworks. The flat head design ensures a secure, flush fit that enhances both safety and aesthetics in finished projects.
