S-94048A290 Length 2" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with hot-dipped galvanized steel coating, ensuring long-lasting performance in humid or outdoor wood applications.
• High-torque installation capability thanks to the external hex drive and hex head design, allowing for secure tightening with standard tools.
• Enhanced holding power in wood through the thread forming tapping method, which displaces material to create strong, vibration-resistant connections.
• Optimized thread engagement with a 3/8" diameter and 7 threads per inch, providing reliable fastening without splitting wood.
• Versatile partial threading design enables precise clamping force control, ideal for varied wood thicknesses and structural joints.
• Rigorous quality assurance by complying with ASME B18.2.1, ASTM A307, and SAE J429 standards, ensuring dimensional accuracy and mechanical reliability.
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting global regulatory requirements for safe usage.

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws are engineered to address common challenges in wood construction, such as moisture-induced corrosion and joint loosening under stress. The external hex drive facilitates high torque application, reducing installation time and preventing tool slippage in demanding sites like outdoor decking or timber framing. The thread forming design eliminates the need for pre-drilling in many softwoods, minimizing labor while maximizing pull-out resistance. By combining a 3/8" diameter with a partially threaded shank, these screws ensure concentrated clamping force at the joint, critical for load-bearing assemblies in furniture, pallets, and structural woodwork. Their compliance with ASME B18.2.1 and material standards guarantees consistent performance, making them a reliable choice for contractors and manufacturers seeking durability and regulatory adherence.

Specification Summary & Compliance

This product adheres to Class 2A thread tolerances as per ASME B18.2.1, with a right-hand thread direction and approximate 7 threads per inch. It meets dimensional and mechanical specifications under ASTM A307 and SAE J429, ensuring interoperability and strength. The screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of restricted hazardous substances. These features support reliable use in wood fastening applications where precision and environmental safety are paramount.
