S-90252A239 Length 1 1/2" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel construction for longer service life in demanding woodworking environments
• Superior material penetration through thread-forming design that creates stronger, more permanent connections in fiberboard and particleboard
• Flush installation capability with standard flat head profile and 82° countersink angle for smooth, professional-looking finishes
• Optimized driving efficiency with No. 3 Phillips drive and pointed tip for quick, straightforward installation without pre-drilling complications
• Reliable partial threading design that provides maximum holding power in the threaded section while allowing for material expansion
• Precision compatibility with standard 3/32" drill bits, eliminating guesswork and ensuring proper hole preparation
• Right-hand threading configuration following industry standards for familiar, intuitive installation by professionals

Professional Applications & Engineering Value

These black-oxide steel wood screws are specifically engineered to address common challenges in fiberboard and particleboard applications, where material density variations can compromise fastener performance. The thread-forming design eliminates the need for tapping by displacing material to create strong, permanent threads that resist pull-out forces. The 82° countersink angle ensures the flat head sits flush with the material surface, preventing snagging while maintaining structural integrity. Made from durable black-oxide coated steel, these screws provide enhanced corrosion resistance for interior woodworking projects, cabinet installations, and furniture assembly. The partially threaded shank allows the unthreaded portion to act as a precision pilot, reducing splitting in engineered wood products while the threaded section delivers maximum holding power where it matters most.

Specification Summary & Compliance

Manufactured to inch system standards with precision No. 10 screw size and 1-1/2" length. Features standard flat head profile with 0.385" head diameter (-0.045" tolerance) and right-hand threading configuration. The thread-forming tapping method creates secure connections without separate tapping operations. Compatible with standard 3/32" drill bits (0.094" diameter) for proper installation. These screws meet industry standards for wood screw applications and are suitable for professional woodworking and construction use.
