S-94048A332 Length 2 1/2" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance through hot-dipped galvanized steel construction, ensuring long-term reliability in outdoor or humid wood applications
• Exceptional holding power with 6 threads per inch and 1.667" minimum thread length, providing secure fastening in demanding wood structures
• Easy installation and removal with external hex drive design, allowing quick assembly using standard tools without cam-out issues
• Reduced splitting risk through thread forming tapping method that displaces material rather than cutting it in wood substrates
• Optimized load distribution with partially threaded shank design, concentrating threads where maximum grip is needed
• Industry-standard compatibility meeting ASME B18.2.1 specifications, ensuring precise dimensional accuracy and interchangeability
• Environmental compliance assurance with RoHS 3 and REACH compliance, meeting global regulatory requirements for safe usage

Professional Applications & Engineering Value

Engineered specifically for heavy-duty wood construction, these hot-dipped galvanized steel hex head screws address critical challenges in structural wood applications. The external hex drive provides superior torque transmission compared to standard drives, preventing stripping during high-torque installation in hardwoods or pressure-treated lumber. The thread forming design creates stronger mating threads in wood by compressing fibers rather than removing material, significantly reducing the risk of wood splitting while improving pull-out resistance. With 1/2" diameter and 6 threads per inch, these screws deliver exceptional shear strength and clamping force for deck framing, timber construction, and outdoor structural projects where corrosion resistance is paramount. The partially threaded configuration ensures optimal performance by allowing the unthreaded shank to act as a dowel, preventing joint movement while the threaded portion provides maximum holding power.

Specification Summary & Compliance

This 1/2" x 2-1/2" hex head wood screw maintains precise dimensional tolerances per ASME B18.2.1 specifications with Class 2A thread fit for reliable performance. Manufactured in compliance with ASTM A307 for carbon steel bolts and SAE J429 for mechanical properties, ensuring consistent quality and strength characteristics. The hot-dipped galvanized surface treatment provides superior corrosion protection compared to electroplated alternatives. Fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations, including the latest SVHC requirements as of June 2023.
