S-92351A638 Length 3 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in humid or outdoor wood applications
• Enhanced torque transmission through the external hex drive design, preventing cam-out and ensuring secure installation
• Reduced splitting and superior holding power with thread forming technology that displaces wood fibers without pre-drilling
• Optimized thread engagement with 2-1/4" minimum thread length providing maximum pull-out resistance in demanding wood connections
• Easy alignment and quick starts thanks to the pointed tip design for precise positioning in wood materials
• Reliable industrial performance meeting ASME B18.2.1 specifications for dimensional accuracy and mechanical properties
• Environmentally compliant construction adhering to RoHS 3 and REACH regulations for safe, sustainable manufacturing

Professional Applications & Engineering Value

Engineered for demanding wood fastening applications, these 18-8 stainless steel hex head wood screws deliver exceptional performance where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for pre-tapping in wood substrates, reducing installation time while creating stronger, more vibration-resistant connections. With 3/8" diameter and 3-1/2" length, these partially threaded screws provide optimal clamping force distribution, making them ideal for heavy-duty wood construction, timber framing, and outdoor structures exposed to environmental elements. The external hex drive ensures maximum torque application without stripping, crucial for industrial assembly lines and construction sites where reliability cannot be compromised.

Specification Summary & Compliance

This 3/8" x 3-1/2" wood screw features inch system measurements with right-hand threading and 7 threads per inch configuration. Manufactured to ASME B18.2.1 standards for dimensional accuracy and mechanical performance, ensuring consistent quality across production batches. The product maintains compliance with RoHS 3 (2015/863/EU) for hazardous substance restrictions and REACH (EC 1907/2006) regulations, confirming environmental responsibility and workplace safety. The 18-8 stainless steel material provides inherent corrosion resistance, while the hex head design with 0.563" width and 1/4" height offers standardized tool compatibility.
