S-94048A407 Length 5" 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 for long-lasting performance in outdoor and humid wood applications
• Superior installation torque and control through external hex drive design that prevents cam-out and allows high-tightening force
• Optimal thread engagement with 4.5 TPI thread forming design that creates strong, permanent threads in wood without pre-drilling
• Enhanced pull-out resistance through partial threading that provides maximum grip in the strongest section of the wood
• Heavy-duty construction capability with 5" length and 3/4" diameter for demanding wood structural applications
• Reliable mechanical performance meeting ASME B18.2.1, ASTM A307, and SAE J429 standards for consistent quality and strength
• Environmental compliance assurance with RoHS 3 and REACH standards for safe, regulated use in commercial projects

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws are engineered to solve critical challenges in wood construction and structural applications. The thread forming design eliminates the need for pre-tapping while creating stronger, more durable threads that resist stripping and pull-out forces. The external hex drive provides superior torque transmission compared to standard drives, preventing cam-out during installation in dense woods. With partial threading and substantial 5" length, these screws concentrate thread engagement where it matters most, providing exceptional holding power for timber framing, deck construction, and heavy wood structural connections. The hot-dipped galvanized coating offers superior corrosion protection, making them ideal for outdoor applications, marine environments, and high-moisture conditions where ordinary fasteners would fail prematurely.

Specification Summary & Compliance

These 3/4" wood screws feature a 0.75" thread diameter with 4.5 threads per inch and right-hand threading. The screws are manufactured to ASME B18.2.1 dimensional standards with material compliance to ASTM A307 and SAE J429 specifications. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring they meet current regulatory requirements for hazardous substances. The thread forming design creates mating threads in wood without removing material, providing superior holding strength in various wood types and applications.
