S-91540A200 Length 1 5/8" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for humid or demanding environments.
• Effective moisture sealing through the integrated stainless steel/rubber washer (0.63" OD), preventing water ingress and material degradation.
• Effortless installation with Type 17 thread cutting design and pointed tip, reducing splitting in wood, plastic, and composites.
• Secure, non-slip fastening enabled by the No. 1 square drive, ensuring high torque transfer and reduced cam-out.
• Optimized load distribution from the flat head and flat washer, minimizing surface damage and maintaining joint integrity.
• Reliable partial threading for controlled grip and reduced risk of over-tightening in softer materials.
• Compliance with global safety standards including RoHS 3 and REACH, ensuring environmental and workplace safety.

Professional Applications & Engineering Value

These 18-8 stainless steel wood screws are engineered to address common fastening challenges in wood, plastic, and wood-plastic composite applications. The Type 17 thread cutting feature eliminates the need for pre-drilling in many cases, significantly speeding up assembly while reducing labor costs. The integrated sealing washer, composed of stainless steel and rubber, creates a durable barrier against moisture, dust, and corrosion—critical for outdoor structures, marine environments, or HVAC installations. The flat head design sits flush with surfaces, providing a clean finish and preventing snagging. With a No. 1 square drive, these screws offer superior torque resistance, making them ideal for high-volume industrial use where reliability and efficiency are paramount.
