S-90252A260 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 various environments
• Superior holding power in engineered wood through thread forming design that creates strong, permanent threads in fiberboard and particleboard
• Flush, professional finish achieved with 82° countersink angle and flat head profile for seamless surface integration
• Efficient installation with Phillips No. 2 drive providing reliable torque transfer and reduced cam-out risk
• Optimized thread engagement through partial threading design that concentrates holding power where needed most
• Precision compatibility with No. 45 drill bit (0.082") for proper pilot hole preparation and secure fastening
• Right-hand threading ensures standard installation familiarity and consistent performance across applications

Professional Applications & Engineering Value

These black-oxide steel wood screws are specifically engineered to address common challenges in fiberboard and particleboard applications where traditional fasteners often struggle with material density and structural integrity. The thread forming design eliminates the need for pre-tapped holes while creating exceptionally strong thread engagement that resists pull-out forces. The 82° countersink angle combined with the flat head profile ensures perfect flush mounting without surface protrusions, making these No. 9 wood screws ideal for furniture manufacturing, cabinetry, and architectural woodworking where both structural performance and aesthetic finish are critical. The self-tapping capability significantly reduces installation time while maintaining consistent holding power in engineered wood materials prone to splitting or compression.

Specification Summary & Compliance

Manufactured to inch system standards with precision Class 2A thread tolerances, these screws feature a 0.177" thread diameter with 10 TPI thread pitch and 1" minimum thread length. The black-oxide surface treatment provides consistent corrosion protection while maintaining dimensional accuracy. Compliant with industry-standard wood screw specifications and manufactured using quality-controlled processes to ensure reliable performance in professional woodworking applications. The screw dimensions and drill bit compatibility (No. 45 / 0.082") follow established wood fastening guidelines for optimal installation results.
