S-91555A133 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to the black-oxide steel coating, extending service life in various environments
• Enhanced holding power in fiberboard and particleboard due to the thread-forming design that creates strong, permanent threads
• Reduced material splitting with the pointed tip and partial threading, ensuring cleaner installations
• Efficient installation with standard Phillips No. 2 drive, compatible with common power tools for faster project completion
• Optimized pre-drilling guidance using a 3/32" drill bit for precise, secure fastening without over-tightening
• Secure, low-profile fastening with the rounded pan head that sits flush against surfaces without snagging
• Reliable right-hand threading for consistent, predictable performance in standard assembly applications

Professional Applications & Engineering Value

These No. 10 wood screws are precision-engineered to address common challenges in fiberboard and particleboard applications, where material integrity and fastener retention are critical. The black-oxide steel construction provides a durable, corrosion-resistant finish that withstands environmental exposure, while the thread-forming tapping method eliminates the need for pre-tapped holes, creating robust internal threads that resist pull-out and loosening over time. The partially threaded design concentrates gripping power along the shank, reducing the risk of board delamination or cracking. Combined with the Phillips pan head, these screws deliver reliable performance in furniture assembly, cabinetry, and construction projects, ensuring long-term structural stability with minimal maintenance.

Specification Summary & Compliance

These screws adhere to standard inch measurements with a thread diameter of 0.19" and approximately 9 threads per inch, ensuring consistent fit and performance. The partially threaded design and right-hand thread direction comply with common industrial practices for wood fasteners. Manufactured from high-quality steel with a black-oxide finish, they meet general industry standards for mechanical fasteners and are suitable for use in compliance with typical RoHS and REACH environmental guidelines, providing a reliable solution for professional and DIY woodworking applications.
