S-95452A166 Length 4" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel coating that protects against rust in demanding wood applications
• Maximum torque transmission through external hex drive design, preventing cam-out and ensuring secure installation
• Enhanced holding power with thread forming technology that compresses wood fibers rather than cutting them
• Optimized thread engagement with 4.5 threads per inch and 2 1/2" minimum thread length for superior pull-out resistance
• Easy alignment and installation with pointed tip design that guides the screw accurately into wood materials
• Reliable industrial performance backed by ASME B18.2.1 standards compliance for consistent quality and dimensional accuracy
• Environmentally responsible manufacturing with full RoHS 3 and REACH compliance for safe industrial use

Professional Applications & Engineering Value

These 3/4" wood screws are engineered to solve critical challenges in wood construction and industrial applications where joint integrity is paramount. The black oxide steel construction provides essential corrosion protection for both indoor and outdoor wood projects, while the thread forming design creates stronger connections by compressing wood fibers rather than removing material. This approach significantly reduces the risk of wood splitting and improves pull-out strength by up to 30% compared to conventional wood screws. The external hex drive configuration ensures maximum torque application without stripping, making these screws ideal for heavy-duty framing, timber construction, and structural wood assemblies where vibration resistance and long-term reliability are critical requirements.

Specification Summary & Compliance

These wood screws feature precise inch system dimensions including 0.75" thread diameter, 4" overall length, and 1 1/8" hex head width for standard wrench compatibility. The partially threaded design with right hand threading follows ASME B18.2.1 specifications for dimensional accuracy and performance standards. Manufacturing compliance includes RoHS 3 (2015/863/EU) for hazardous substance restriction and REACH (EC 1907/2006) for chemical safety, ensuring these fasteners meet the highest environmental and regulatory requirements for industrial wood fastening applications.
