S-90123A146 Length 4" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction
• High-torque installation capability provided by the external hex head design for secure fastening
• Excellent holding power in wood achieved through the thread forming tapping method
• Optimized for deep penetration with a 4" length and partially threaded shank
• Reliable dimensional consistency ensured by compliance with the ASME B18.2.1 standard
• Safe for regulated industries with full RoHS 3 and REACH compliance
• Reduced risk of material splitting due to the pointed tip and controlled thread engagement

Professional Applications & Engineering Value

These 316 stainless steel hex head wood screws are engineered to solve critical challenges in demanding wood construction and industrial applications. The thread forming design creates strong, permanent threads in wood substrates without pre-drilling in many cases, significantly speeding up assembly while providing exceptional pull-out resistance. The external hex drive allows for high torque application, making them ideal for heavy-duty framing, timber construction, and outdoor structures where vibration resistance is paramount. Manufactured from corrosion-resistant 316 stainless steel, these screws deliver long-term reliability in humid, marine, or chemical-exposed environments, preventing fastener failure and reducing maintenance costs over the lifecycle of the project.

Specification Summary & Compliance
