S-95452A108 Length 4" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Enhanced holding power through thread forming design that creates permanent, vibration-resistant connections in wood materials
• Superior corrosion resistance with black oxide coating that protects against rust and extends service life in various environments
• Maximum torque application with external hex drive design that prevents cam-out and allows for high-tightening forces
• Reduced wood splitting with partially threaded shank that concentrates gripping power where needed most
• Quick and easy installation with pointed tip that self-starts in wood without requiring pre-drilling in many applications
• Reliable performance meeting ASME B18.2.1 standards ensuring consistent quality and dimensional accuracy
• Environmental compliance with RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

These 1/4"-10 partially threaded wood screws are engineered to solve common wood fastening challenges in construction, furniture manufacturing, and structural woodworking applications. The black oxide steel construction provides excellent durability while the thread forming design creates stronger, more permanent connections than conventional cutting threads. The external hex drive allows for high-torque installation without stripping, making them ideal for heavy-duty framing, deck building, and timber construction where vibration resistance is critical. The partially threaded configuration prevents wood splitting by allowing the unthreaded shank to act as a dowel, while the threaded portion delivers maximum pull-out resistance. These features combine to create reliable, long-lasting wood connections that withstand seasonal movement and structural loads.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 specifications with Class 2A thread tolerances, these screws ensure precise fit and consistent performance. The 1/4"-10 thread configuration with right-hand direction and 2-1/2" minimum thread length provides optimal engagement in wood substrates. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory acceptance across international markets. The inch system measurements maintain dimensional accuracy for reliable integration with standard woodworking components and tools.
