S-95526A175 Length 2 1/2" ASTM A153 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with hot-dipped galvanized steel coating for long-lasting performance in outdoor and high-moisture wood applications
• Enhanced torque transmission through the external hex head design, preventing cam-out and ensuring secure fastening
• Optimal wood holding power with partial threading that provides maximum grip while reducing wood splitting
• Quick installation with pointed tip and thread-forming design that creates strong mating threads in wood materials
• Increased load distribution thanks to the integrated flange that eliminates the need for separate washers
• Reliable dimensional consistency with precise 1/4" diameter and 2-1/2" length for predictable performance in wood construction projects
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing

Professional Applications & Engineering Value

These hot-dipped galvanized steel wood screws deliver exceptional engineering value for construction professionals and woodworking applications. The hex head design provides superior torque application capability, allowing for high-tension fastening in demanding structural wood connections. The thread forming technology creates precise mating threads in wood substrates without removing material, resulting in stronger connections and reduced splitting in both softwoods and hardwoods. The partial threading configuration concentrates holding power where it's needed most while minimizing stress concentration points. With corrosion-resistant hot-dipped galvanization, these screws maintain structural integrity in exterior applications, deck building, fencing, and outdoor furniture where moisture exposure would compromise standard fasteners. The integrated flange design distributes clamping force over a wider surface area, preventing pull-through in softer wood materials.

Specification Summary & Compliance

These wood screws feature a 1/4" diameter with 10 threads per inch in right-hand orientation and 2-1/2" length with 1-1/4" minimum thread length. Manufactured to meet ASTM A153 specifications for zinc coating thickness and quality, ensuring consistent corrosion protection. The screws comply with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. The external hex drive measures 3/8" across flats with 0.28" head height and features a 0.56" flange diameter for optimal load distribution in wood fastening applications.
