S-90123A389 Length 4" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and outdoor applications
• Maximum torque transmission through the external hex head design, preventing tool slippage during installation
• Enhanced holding power in wood using thread forming technology that displaces material without creating chips
• Optimized load distribution with partial threading, reducing the risk of wood splitting under stress
• Precise dimensional accuracy meeting ASME B18.2.1 standards for reliable interchangeability
• Environmental and workplace safety with full compliance to RoHS 3 and REACH regulations
• Long-term durability in demanding industrial applications thanks to the pointed tip for easier starting

Professional Applications & Engineering Value

These 316 Stainless Steel hex head wood screws are engineered to solve critical challenges in industrial wood fastening. The thread forming design eliminates chip removal, creating stronger threads in wood substrates while preventing material weakness. With partial threading, the unthreaded shank provides superior clamp-up force distribution, significantly reducing wood splitting in heavy timber construction. The external hex drive delivers maximum torque transfer for high-tension applications, while the corrosion-resistant 316 stainless steel composition ensures long-term performance in marine, chemical processing, and outdoor environments where moisture and corrosive elements are present.
