S-90031A552 Length 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide Steel coating, extending screw life in various wood environments.
• Enhanced driving efficiency with Phillips No. 2 drive and flat head design, reducing cam-out and ensuring secure installation.
• Excellent holding power through thread forming technology, which creates strong, permanent threads in wood without pre-tapping.
• Optimized for wood applications with a pointed tip and partial threading for faster insertion and reduced wood splitting.
• Precise countersinking with an 82° flat head profile, allowing flush mounting in hardwood and softwood with recommended drill bits.
• Reliable performance in diverse woods, using specific drill sizes (5/64" for hardwood, 1/16" for softwood) for accurate pilot holes.
• Compliance with international safety standards, including RoHS 3 and REACH, ensuring safe use in industrial and commercial settings.

Professional Applications & Engineering Value

These No. 6 x 1/2" Black-Oxide 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 robust, permanent threads, eliminating the need for pre-drilled threads and reducing installation time. Made from durable Black-Oxide Steel, they resist rust and corrosion, ideal for indoor and mildly humid environments. The Phillips flat head with an 82° countersink angle ensures a clean, flush finish in applications like furniture assembly, cabinetry, and wooden structures, while the partial threading minimizes stress on the wood. This combination of right-hand threading and precise dimensions delivers consistent performance, enhancing project reliability and reducing maintenance costs for professionals.

Specification Summary & Compliance
