S-95452A111 Length 5 1/2" 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 woodworking environments
• Maximum torque application through external hex head design that prevents cam-out and allows for high-tightening force
• Secure wood fastening with thread forming technology that creates strong, permanent threads without pre-drilling
• Enhanced pull-out resistance through partial threading that concentrates holding power where it's needed most
• Easy installation with pointed tip that self-starts in wood materials and right-hand threading for standard installation
• Heavy-duty construction with substantial 5½" length and ¼" diameter for demanding structural wood applications
• Reliable performance backed by ASME B18.2.1 certification ensuring consistent quality and dimensional accuracy

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered specifically for professional woodworking applications where failure is not an option. The black oxide steel construction provides exceptional corrosion resistance, making them ideal for both interior and exterior wood projects exposed to moisture or humidity. The thread forming design eliminates the need for pre-tapping by displacing wood fibers to create stronger, more secure threads that won't strip under load. With their external hex drive and substantial 5½" length, these screws deliver maximum clamping force for structural connections in timber framing, deck construction, furniture manufacturing, and architectural woodwork. The partial threading ensures that unthreaded shank sections provide superior shear strength while threaded portions deliver exceptional pull-out resistance.

Specification Summary & Compliance

Manufactured to exacting ASME B18.2.1 standards with Class 2A thread tolerances ensuring precise fit and consistent performance. These 1/4"-10 thread screws feature right-hand threading and are compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The inch system measurement provides dimensional accuracy with 0.25" thread diameter, 10 threads per inch, and 0.438" hex head width for standardized tool compatibility across professional woodworking applications.
