S-92371A416 Length 1 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black zinc plating that protects against rust in demanding wood applications
• Enhanced driving efficiency through external hex head design that prevents cam-out and allows high-torque installation
• Maximum holding power achieved through thread forming design that compresses wood fibers without pre-drilling
• Reduced material splitting with partially threaded shank that concentrates grip strength where needed most
• Quick start penetration thanks to pointed tip design that self-guides into wood surfaces
• Industry-standard compatibility with 1/4"-10 thread pattern that matches common woodworking applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for responsible manufacturing

Professional Applications & Engineering Value

These black zinc-plated steel wood screws deliver exceptional performance in demanding wood construction and fabrication applications. The thread forming design eliminates the need for pre-tapping by displacing and compressing wood fibers, creating superior pull-out resistance that prevents joint failure under vibration or load stress. The external hex drive system provides maximum torque transmission without stripping, while the partial threading concentrates gripping power at critical connection points. The combination of 1/4"-10 right-hand threading and pointed tip ensures rapid installation in hardwood, softwood, and engineered wood products, making these screws ideal for structural framing, furniture manufacturing, and outdoor wood projects where environmental exposure requires the protective black zinc plating.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 dimensional standards with Class 2A thread tolerances, these wood screws feature precise 1/4"-10 thread pitch and 1-1/2" overall length with 1" minimum thread engagement. The black zinc-plated steel construction meets industry specifications for corrosion protection, while full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures responsible manufacturing practices. The external hex drive (0.438" head width) and thread forming tapping method provide reliable performance in wood applications requiring high tensile strength and vibration resistance.
