S-98685A580 Length 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to high-quality brass construction, ensuring long-lasting performance in humid or outdoor woodworking environments.
• Effortless installation with the Phillips No. 2 drive, providing a secure grip and reducing cam-out for faster, more reliable fastening.
• Excellent holding power from the thread forming design and 20 threads per inch, creating strong, permanent threads in wood without pre-tapping.
li>Versatile application compatibility for both hardwood (using 5/64" drill bit) and softwood (using 1/16" drill bit), simplifying inventory and project planning.
• Reduced wood splitting with the pointed tip and partially threaded shank, allowing for precise placement and minimizing material damage.
• Enhanced aesthetic appeal with a rounded head profile that sits flush or slightly proud, offering a clean, finished look for visible applications.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe, sustainable use in professional and consumer products.

Professional Applications & Engineering Value

These brass wood screws are engineered to address common challenges in woodworking and joinery, such as corrosion in high-moisture environments and the need for reliable, thread-forming fasteners that eliminate the requirement for separate tapping operations. The right-hand thread with 20 TPI provides optimal pull-out strength in both hardwood and softwood applications, while the Phillips drive ensures consistent torque transfer without stripping. The partially threaded design allows the screw to draw materials together tightly, reducing the risk of wood splitting—a critical advantage in fine woodworking, furniture assembly, and outdoor structures where corrosion-resistant brass is essential for durability against the elements.
