S-95452A136 Length 5" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel coating for extended service life in demanding wood applications
• Enhanced torque transmission through external hex drive design prevents stripping and enables high-tightening force
• Exceptional holding power with thread forming technology that creates stronger, permanent threads in wood materials
• Optimized length-to-diameter ratio (5" length, 3/8" diameter) provides deep penetration for heavy-duty wood connections
• Reduced installation effort with pointed tip and 7 threads per inch configuration for smoother driving
• Reliable partial threading design ensures maximum grip in the engagement zone while minimizing material stress
• Industry-standard compatibility with 1/4" head height and 0.563" head width for standard wrench applications

Professional Applications & Engineering Value

These 3/8" x 5" black oxide steel hex head wood screws are engineered to solve critical fastening challenges in wood construction and manufacturing. The thread forming design eliminates the need for pre-tapping by displacing wood fibers to create permanent, high-strength threads that resist loosening under vibration and load cycles. The external hex drive system provides superior torque transmission compared to Phillips or slotted drives, preventing cam-out and ensuring proper seating in dense hardwoods or pressure-treated lumber. The black oxide surface treatment offers enhanced corrosion protection for both indoor and protected outdoor applications, while the partially threaded shank allows the unthreaded portion to act as a precision pilot, reducing wood splitting in critical joinery applications. These features combine to deliver reliable performance in furniture manufacturing, timber framing, deck construction, and structural wood assemblies where maximum pull-out resistance and long-term reliability are essential.

Specification Summary & Compliance

These wood screws feature 3/8" diameter with 7 threads per inch in right-hand configuration and Class 2A thread tolerances. The partially threaded design provides 3" minimum thread length on the 5" overall screw. Manufacturing and dimensional specifications strictly comply with ASME B18.2.1 standards for hex head screws. Environmental compliance is verified through RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance as of January 17, 2023, ensuring restricted substance adherence for global industrial applications.
