S-92371A581 Length 3" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black zinc-plated steel construction for long-lasting performance in various environments
• Superior driving efficiency with external hex head design allowing high torque application and reduced cam-out risk
• Excellent holding power through thread forming design that creates strong, permanent threads in wood materials
• Optimized thread engagement with 2" minimum thread length ensuring maximum grip and pull-out resistance
• Easy installation with pointed tip and partial threading for quick starting and reduced splitting in wood applications
• Reliable performance meeting ASME B18.2.1 standards for dimensional accuracy and mechanical properties
• Environmental compliance with RoHS 3 and REACH regulations for safe, sustainable manufacturing

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered to solve common fastening challenges in wood construction and fabrication. The black zinc-plated steel construction provides superior corrosion protection, extending service life in both indoor and outdoor applications. The thread forming design creates compression in the wood fibers rather than cutting them, resulting in significantly higher pull-out resistance and reduced likelihood of loosening under vibration. The external hex drive allows for high torque application, making these screws ideal for structural wood connections, timber framing, and heavy-duty furniture assembly where maximum clamping force is required. The combination of 3/8" diameter and 7 threads per inch provides the optimal balance between shear strength and thread engagement for demanding wood fastening applications.

Specification Summary & Compliance

These wood screws feature 3/8" diameter with 7 threads per inch in right-hand direction and Class 2A thread fit per ASME standards. The partially threaded design with 2" minimum thread length ensures proper engagement while the pointed tip facilitates easy starting. Manufactured to ASME B18.2.1 specifications for dimensional accuracy and mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for hazardous substance restrictions.
