S-90610A110 Length 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various environmental conditions.
• Enhanced holding power in wood through thread forming technology, which creates strong, secure fastenings without pre-tapping.
• Clean, flush installation with a standard flat head and 82° countersink angle, reducing surface damage and improving aesthetics.
• Efficient driving and reduced cam-out thanks to the square drive design, allowing for high torque application and minimal tool slippage.
• Optimized pull-out resistance from the partially threaded shank, providing reliable grip in both hardwood and softwood applications.
• Versatile compatibility with recommended drill bit sizes (1/16" for hardwood, 3/64" for softwood), simplifying preparation and installation.
• Compliance with industrial safety standards including RoHS 3 and REACH, ensuring safe, environmentally responsible use in professional settings.

Professional Applications & Engineering Value

These No. 4 zinc-plated steel wood screws are engineered to address common challenges in woodworking and construction, such as material splitting and weak fastening. The thread forming design displaces wood fibers to create a tight, permanent thread, eliminating the need for pre-drilled threads and reducing installation time. Made from durable zinc-plated steel, they resist rust and corrosion, making them ideal for indoor and limited outdoor applications. The flat head with an 82° countersink ensures a smooth, flush finish, minimizing protrusions and enhancing safety in furniture, cabinetry, and structural wood assemblies. Their partially threaded configuration concentrates holding force near the tip, providing exceptional resistance to pull-out forces in both hardwood and softwood, which is critical for maintaining integrity in dynamic loads.

Specification Summary & Compliance

This product features a thread diameter of 0.112" with approximately 22 threads per inch, adhering to standard inch measurements for precise fits. The partially threaded design and pointed tip facilitate easy insertion and optimal grip. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring the absence of hazardous substances and meeting global environmental and safety standards for industrial use.
