Professional Applications & Engineering Value
These No. 4 oval head wood screws solve critical fastening challenges in woodworking and construction applications. The 18-8 stainless steel material provides exceptional corrosion resistance, making these slotted drive screws ideal for exterior wood structures, marine environments, and high-moisture areas where rust prevention is essential. The thread forming tapping method creates strong, permanent threads in wood without pre-tapping, while the partially threaded design concentrates holding power where needed most. The pointed tip ensures easy starting and reduced splitting in both hardwood and softwood, supported by specific drill bit recommendations for each material type. These right hand threaded screws deliver reliable performance for furniture assembly, cabinetry, deck building, and general wood construction where durable fastening solutions are required.
