S-92351A642 Length 4 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for humid or outdoor wood applications
• Maximum torque transmission through the external hex drive design, preventing cam-out during high-torque installation
• Enhanced wood gripping strength from thread-forming technology that creates stronger, permanent threads in wood materials
• Optimized load distribution with partial threading design that concentrates holding power where needed most
• Quick, easy starts thanks to the pointed tip design that reduces pre-drilling requirements
• Heavy-duty performance with 4-1/2" length and 3/8" diameter for demanding wood construction applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing

Professional Applications & Engineering Value

Engineered for demanding wood construction and industrial applications, these 18-8 stainless steel hex head wood screws deliver exceptional performance where corrosion resistance and structural integrity matter most. The thread-forming tapping method creates permanent, high-strength threads in wood substrates without pre-tapping, eliminating the risk of stripped threads in critical joints. The external hex drive configuration ensures maximum torque application without slippage, making these screws ideal for heavy timber construction, deck building, and structural wood framing. With partial threading design, the unthreaded shank provides superior clamping force while minimizing wood splitting in dense hardwoods or pressure-treated lumber. These features combine to create reliable, long-lasting fastening solutions for outdoor structures, marine environments, and industrial wood assemblies where exposure to moisture and environmental elements would compromise ordinary fasteners.

Specification Summary & Compliance

This 3/8" x 4-1/2" wood screw features right-hand threading with 7 threads per inch and a minimum thread length of 2-3/4". Manufactured to ASME B18.2.1 specifications for dimensional accuracy and performance standards. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting the latest environmental regulations for hazardous substances. The inch system measurement ensures compatibility with North American wood construction standards and specifications.
