S-94048A380 Length 4" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with hot-dipped galvanized steel coating, ideal for outdoor and high-moisture wood applications
• Superior torque transmission and anti-stripping performance from the external hex head design, ensuring reliable fastening in demanding conditions
• Optimized thread engagement and reduced splitting risk with partial threading, providing excellent holding power in wood materials
• High-strength construction meeting ASTM A307 and SAE J429 standards, guaranteeing consistent performance under heavy loads
• Easy installation with thread-forming tapping that creates strong, secure threads without pre-drilling in many wood types
• Right-hand threading compatibility with standard tools, streamlining assembly processes in industrial settings
• Environmental and regulatory compliance with RoHS 3 and REACH standards, ensuring safe use in global markets

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws are engineered to address common failure points in industrial wood fastening applications. The 5/8" diameter and 4" length provide substantial shear strength for structural connections in timber construction, outdoor decking, and heavy-duty pallets. The thread forming design eliminates the need for precise pilot holes in many wood types, reducing installation time while maintaining superior pull-out resistance. The external hex drive prevents cam-out during high-torque applications, crucial for automated assembly lines. The hot-dipped galvanized coating offers robust protection against rust and corrosion, extending service life in harsh environments where moisture exposure would compromise standard fasteners.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 dimensional specifications with Class 2A thread tolerances for consistent fit. The 0.625" diameter features approximately 5 threads per inch with 2.667" minimum thread length and partial threading configuration. Fully compliant with ASTM A307 material standards and SAE J429 mechanical properties. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
