S-91478A724 Length 3" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for long-lasting performance in demanding wood applications
• Exceptional holding power through thread forming design that creates stronger, more secure connections in wood materials
• Easy installation and removal with external hex drive and 3/4" head width for reliable tool engagement and torque transfer
• Optimized thread engagement with 1/2"-13 coarse threads providing maximum pull-out resistance in wood substrates
• Versatile partial threading allowing unthreaded shank section to act as a built-in washer for improved clamping force
• Industry-standard compliance meeting ASME B18.2.1 specifications for consistent quality and dimensional accuracy
• Environmental responsibility with RoHS 3 and REACH compliance for safe use in industrial and commercial settings

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered to solve critical fastening challenges in wood construction and industrial applications. The zinc-plated steel construction provides essential corrosion protection for both indoor and outdoor projects, while the thread forming technology eliminates the need for pre-drilling in many applications, creating stronger molecular bonds with wood fibers. The external hex drive delivers superior torque transmission compared to Phillips or slotted drives, preventing cam-out and ensuring secure installations. With 3" length and 1/2"-13 coarse threads, these screws offer exceptional pull-out resistance in structural wood connections, making them ideal for timber framing, deck construction, and heavy furniture assembly where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

Manufactured to exacting ASME B18.2.1 standards, these wood screws maintain precise dimensional tolerances including Class 2A thread fit for consistent performance. The partially threaded design features a 2" minimum thread length on the 3" overall length, with pointed tip for easier starting. The zinc-plated steel construction meets rigorous industry specifications while maintaining full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe handling and use in professional applications worldwide.
