S-91478A583 Length 1" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in various environments
• Enhanced driving efficiency with external hex head design, allowing for high torque application and reduced tool slippage
• Excellent holding power in wood due to thread forming tapping method, which creates strong, secure threads without pre-drilling in many cases
• Full-length threading provides consistent grip along the entire 1" length, maximizing pull-out resistance in wood applications
• Precise 9 TPI thread pitch delivers optimal thread engagement for reliable fastening in wooden materials
• Right-hand thread direction ensures standard, intuitive installation for most operators
• Compliance with industry standards including ASME B18.2.1, guaranteeing dimensional accuracy and interchangeability

Professional Applications & Engineering Value

These 5/16" zinc-plated steel wood screws are engineered to address common challenges in wood fastening applications, particularly in industrial and construction settings. The thread forming design creates permanent, high-strength threads in wood substrates, eliminating the need for tapping operations and reducing installation time. The fully threaded configuration ensures maximum surface contact along the entire 1" length, providing superior resistance to pull-out forces in furniture manufacturing, structural wood assemblies, and wood-to-wood connections. The external hex drive accommodates high torque applications without cam-out, while the zinc plating offers reliable protection against corrosion in both indoor and moderate outdoor environments. These features make these screws ideal for demanding wood fastening applications where reliability, speed of installation, and long-term performance are critical.

Specification Summary & Compliance

These wood screws feature precision 5/16" thread diameter with 9 threads per inch and Class 2A thread tolerances per ASME B18.2.1 specifications. The 1" length provides 3/4" minimum thread length for secure fastening. Manufacturing complies with ASME B18.2.1 standards for dimensional accuracy and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restricted substance compliance for industrial applications.
