S-95452A141 Length 2 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel construction for extended service life in demanding wood applications
• Maximum torque transmission through external hex head design preventing cam-out during high-torque installation
• Enhanced pull-out resistance with thread forming tapping method that creates stronger mating threads in wood substrates
• Optimized thread engagement featuring 6 threads per inch for superior holding power in both soft and hard woods
• Reduced splitting risk with partially threaded shank design that minimizes wood stress concentration
• Quick alignment and penetration thanks to pointed tip geometry for faster installation in wood materials
• Industry-standard compatibility with 3/4" head width accommodating standard wrench sizes for efficient installation

Professional Applications & Engineering Value

These black oxide steel hex head wood screws are engineered to address critical challenges in industrial wood fastening applications. The thread forming design eliminates the need for pre-drilling in many wood types, creating permanent, high-strength connections that resist vibration loosening. The external hex drive system provides superior torque transmission compared to Phillips or slotted drives, preventing stripping during high-torque installation in heavy-duty construction and industrial wood assemblies. The black oxide surface treatment offers enhanced corrosion protection, making these screws ideal for interior applications where moisture resistance is required without the cost of stainless steel. The partially threaded configuration ensures maximum clamping force while minimizing wood splitting in critical structural connections.

Specification Summary & Compliance

Manufactured to exacting ASME B18.2.1 dimensional standards with Class 2A thread tolerances ensuring consistent performance and interchangeability. These 1/2" diameter wood screws feature 6 threads per inch with 1-3/4" minimum thread length and 2-1/2" overall length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for regulated industrial and commercial applications where material restrictions apply.
