S-90252A257 Length 3/4" Wood Screws

Key Features & Benefits at a Glance

• Superior holding power in engineered wood through thread forming technology that creates strong, permanent threads in fiberboard and particleboard
• Corrosion-resistant black-oxide steel construction ensures long-lasting performance in various environmental conditions
• Flush installation capability with 82° countersink angle and flat head design for clean, professional finishes
• Enhanced drive stability with Phillips No. 2 drive style that reduces cam-out and improves installation efficiency
• Full threading along the 3/4" length provides maximum grip and pull-out resistance throughout the entire fastener engagement
• Precision sizing compatibility with recommended No. 45 drill bit (0.082" diameter) for optimal thread formation and material integrity
• Right-hand threading with 10 threads per inch delivers smooth installation and reliable fastening performance

Professional Applications & Engineering Value

These No. 9 wood screws are specifically engineered to address the unique challenges of fastening in fiberboard and particleboard applications. The thread forming design eliminates the need for pre-tapped holes while creating strong, permanent threads that resist stripping and pull-out. Made from durable black-oxide steel, these screws provide excellent corrosion resistance for long-term reliability in woodworking projects. The flat head profile with 82° countersink angle ensures flush mounting without surface protrusions, while the Phillips No. 2 drive offers secure tool engagement during installation. These fully threaded screws maximize surface contact area, distributing stress evenly and preventing material damage in engineered wood products where traditional fasteners might fail.

Specification Summary & Compliance

These wood screws feature precision 0.177" thread diameter with 10 threads per inch in right-hand orientation, manufactured to standard inch system tolerances. The flat head design maintains a head diameter of 0.358" with -0.042" tolerance for consistent performance. The thread forming tapping method creates secure fastening without pre-threading requirements. These fasteners are designed for use with No. 45 drill bit (0.082" diameter) and comply with standard industrial specifications for wood screw applications in engineered wood materials.
