S-95452A144 Length 4" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel coating for extended service life in demanding environments
• Maximum torque transmission through external hex head design, preventing cam-out during high-torque applications
• Enhanced holding power with thread-forming tapping method that creates stronger mating threads in wood materials
• Optimized thread engagement through partial threading design, providing superior clamping force where needed most
• Precise dimensional accuracy meeting ASME B18.2.1 specifications for reliable, consistent performance
• Environmental compliance with RoHS 3 and REACH regulations, ensuring workplace safety and regulatory adherence
• Quick installation with right-hand threading and pointed tip for easier starting and faster driving into wood substrates

Professional Applications & Engineering Value

Our heavy-duty 1/2"-13 wood screws are engineered to address critical challenges in wood construction and industrial applications. The black oxide steel construction provides exceptional corrosion resistance, making these screws ideal for environments where moisture or chemical exposure could compromise fastener integrity. The external hex head design ensures maximum torque application without stripping, while the thread-forming capability creates stronger, more durable connections in wood by displacing material rather than removing it. This partially threaded configuration concentrates clamping force precisely where needed, preventing joint loosening in structural wood assemblies, timber framing, and heavy-duty wood construction projects where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

This 1/2"-13 x 4" wood screw features precise dimensional tolerances with a 0.5" thread diameter and 6 threads per inch configuration. The fastener meets ASME B18.2.1 manufacturing specifications, ensuring consistent quality and performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory adherence for industrial applications. The partially threaded design with 2 1/2" minimum thread length provides optimal performance in wood joining applications, while the right-hand threading and pointed tip facilitate efficient installation in various wood materials.
