S-90252A237 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating, extending service life in various workshop environments
• Enhanced holding power through thread forming design that creates stronger, more permanent connections in fiberboard and particleboard
• Clean, flush installation with 82° countersink angle and flat head design that sits perfectly flush with material surfaces
• Reduced material splitting with pointed tip and partial threading that minimizes stress concentration in wood composites
• Optimized drive efficiency with No. 3 Phillips drive for secure tool engagement and reduced cam-out during installation
• Precision compatibility with 3/32" drill bit for perfectly sized pilot holes, ensuring straight installation and maximum thread engagement
• Versatile application range with 1-1/4" length providing sufficient penetration depth for various thicknesses of engineered wood materials

Professional Applications & Engineering Value

These black-oxide steel wood screws are engineered specifically for the unique challenges of fiberboard and particleboard applications. The thread forming design eliminates the need for tapping while creating stronger, more reliable connections by compressing material fibers rather than removing them. This approach significantly reduces the risk of material failure common in engineered wood products. The 82° countersink angle ensures heads sit perfectly flush, preventing surface protrusions that could interfere with finishing processes. With 0.19" thread diameter and 9 TPI configuration, these screws provide optimal thread engagement without compromising material integrity, making them ideal for furniture manufacturing, cabinet installation, and structural woodworking projects where pull-out resistance is critical.

Specification Summary & Compliance

These No. 10 wood screws feature precise dimensional tolerances including 0.385" head diameter with -0.045" tolerance and 0.838" minimum thread length. Manufactured to industry standards for right-hand threaded, partially threaded fasteners with standard flat head profile. The thread forming tapping method ensures consistent performance while the black-oxide surface treatment provides corrosion protection. Compatible with standard 3/32" drill bits (0.094" diameter) for proper pilot hole preparation. Engineered for optimal performance in wood composite materials with compliance to relevant industrial fastening specifications.
