S-99917A515 Length 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with durable brass construction, ideal for long-lasting performance in humid or outdoor wood applications.
• Enhanced holding power through thread forming design that displaces material for a tight, secure fit without pre-tapping.
• Clean, finished appearance with oval head that sits flush in wood surfaces when paired with an 82° countersink angle.
• Efficient installation using a No. 2 Phillips drive, reducing cam-out and allowing for high-torque application with common tools.
• Optimized for wood types with specific drill bit sizes: 5/64" for hardwood and 1/16" for softwood, ensuring precise, split-free fastening.
• Reliable partial threading that provides strong grip in the threaded section while minimizing wood splitting in sensitive areas.
• Compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible use in commercial projects.

Professional Applications & Engineering Value

These No. 6 brass wood screws are engineered to address common challenges in woodworking and construction, such as material splitting and corrosion. The thread forming design creates strong, permanent threads in wood without the need for pre-drilled threads, reducing installation time and improving pull-out resistance. Made from brass, they resist rust and degradation in moist environments, making them ideal for outdoor furniture, cabinetry, and marine applications. The oval head with Phillips drive offers a balance of aesthetic appeal and practical installation, seating neatly into wood with an 82° countersink for a smooth finish. Partially threaded shanks concentrate holding force where needed while minimizing stress on the wood, ensuring durable, professional-grade assemblies in both hardwood and softwood projects.
