S-91478A548 Length 1 3/4" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for long-lasting performance in humid or outdoor wood applications
• Superior torque transmission through external hex drive design, preventing cam-out and ensuring secure installation
• Optimized wood fastening with partially threaded shank that provides maximum pull-out resistance and reduces wood splitting
• Reliable thread engagement from thread forming design that creates strong, permanent threads in wood materials
• Industry-standard compatibility with 1/4"-10 thread specification ensuring interchangeability with existing hardware
• Extended thread length (1.28" minimum) for deeper penetration and enhanced holding power in thick wood sections
• Environmental compliance meeting RoHS 3 and REACH regulations for safe use in commercial and industrial settings

Professional Applications & Engineering Value

These zinc-plated steel hex head wood screws are engineered to address common challenges in wood construction and manufacturing. The thread forming design eliminates the need for pre-drilling in many applications, reducing installation time while creating stronger thread engagement than conventional cutting screws. The external hex drive provides exceptional torque capability, preventing stripping during high-torque applications in hardwood or composite materials. The partially threaded configuration concentrates holding power where it's needed most, minimizing material stress while maximizing pull-out resistance. These features make these 1/4"-10 wood screws ideal for structural wood assemblies, furniture manufacturing, deck construction, and industrial wood pallets where reliability and durability are critical.

Specification Summary & Compliance

Manufactured to precise ASME B18.2.1 standards with Class 2A thread tolerances ensuring consistent performance and interchangeability. The screws feature a 1/4" diameter with 10 threads per inch in right-hand orientation and 1-3/4" overall length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory acceptance for industrial distribution and use.
