S-90252A115 Length 1 1/2" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with Black-Oxide Steel coating, extending screw life in various environments
• Superior holding power in engineered wood through thread-forming design that compacts material for a secure, vibration-resistant fit
• Flush, professional finish with an 82° countersink angle and flat head that sits seamlessly in fiberboard and particleboard
• Reduced installation time and effort with Phillips drive (No. 2) for common tool compatibility and thread-forming tip that often eliminates pre-drilling
• Optimized for woodworking precision with a No. 8 diameter (0.164") and 11 threads per inch for balanced grip and minimal splitting
• Versatile partial threading allowing unthreaded shank to pull materials tightly together without thread interference
• Reliable dimensional accuracy ensuring consistent performance across batches for professional projects

Professional Applications & Engineering Value

These Black-Oxide Steel wood screws are engineered to address common challenges in fiberboard and particleboard applications, where material density can lead to splitting or poor fastener retention. The thread-forming tapping method displaces wood fibers rather than cutting them, creating a tighter grip that resists loosening under stress or vibration. Combined with the 82° flat head profile, this design ensures a flush mount that enhances aesthetic appeal and prevents snagging. The Phillips drive style offers widespread tool compatibility, speeding up assembly in high-volume woodworking and construction settings. By minimizing the need for pre-drilling in many cases, these screws reduce labor time while maintaining superior holding power, making them ideal for cabinetry, furniture, and structural panel installations.

Specification Summary & Compliance

This product adheres to standard inch measurements with a No. 8 screw size, 1-1/2" length, and 0.164" thread diameter with approximately 11 threads per inch. The flat head features a head diameter of 0.332" (tolerance: -0.04") and standard profile for consistent countersinking. Threads are right-hand and partially threaded, with a minimum thread length of 1". Manufactured to common industrial specifications for dimensional accuracy, these screws are suitable for use with a 5/64" drill bit (0.078" diameter) when pre-drilling is required. The Black-Oxide finish provides basic corrosion protection, and materials comply with RoHS and REACH environmental standards for safe use in various applications.
