S-91555A126 Length 2 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide Steel coating, extending screw life in various environmental conditions
• Enhanced holding power in fiberboard and particleboard through thread forming technology that creates strong, permanent threads without pre-tapping
• Reduced wood splitting with partially threaded design that concentrates grip where needed most
• Quick and precise installation with pointed tip and Phillips No. 2 drive for efficient driving with standard 5/64" drill bits
• Consistent performance with 11 TPI thread pattern ensuring reliable engagement in engineered wood materials
• Clean finished appearance with rounded pan head design that sits flush against material surfaces
• Optimized for industrial woodworking with right-hand threading compatible with standard power tools and assembly processes

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 fail. The thread forming technology eliminates the need for pre-tapped holes while creating superior thread engagement that resists pull-out in low-density materials. The partially threaded design ensures maximum clamping force where it matters most, preventing material damage while maintaining structural integrity. With their Phillips pan head configuration and precise 0.164" thread diameter, these screws deliver consistent performance in high-volume manufacturing environments, furniture assembly, and construction projects requiring reliable fastening in engineered wood products.

Specification Summary & Compliance

Manufactured to inch system standards with Class 2A thread tolerances for consistent fit and performance. The screws feature right-hand threading with 11 threads per inch and partial threading extending 1.675" from the pointed tip. Compliant with industry standards for wood screw applications and suitable for use with standard 5/64" drill bits. The Black-Oxide surface treatment provides corrosion protection while maintaining dimensional stability. These fasteners meet quality control specifications for industrial woodworking and construction applications, ensuring reliable performance in professional settings.
