S-90031A177 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for long-lasting performance in various environments
• Superior pull-out resistance due to thread forming design that creates strong, permanent threads in wood materials
• Clean, flush finishing with 82° countersink angle that allows the flat head to sit perfectly flush with wood surfaces
• Secure installation and reduced cam-out with No. 2 Phillips drive that provides excellent torque transfer
• Optimized wood gripping performance through partial threading that concentrates holding power where needed most
• Versatile material compatibility with specific drill bit recommendations for both hardwood and softwood applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, regulated manufacturing

Professional Applications & Engineering Value

These zinc-plated steel wood screws are engineered to solve common fastening challenges in woodworking and construction applications. The thread forming design eliminates the need for pre-tapped holes while creating stronger thread engagement that significantly improves pull-out resistance compared to conventional wood screws. The flat head with 82° countersink angle provides a professional, flush finish that enhances both aesthetics and safety in finished wood products. The partial threading concentrates the gripping power in the engagement zone while allowing the unthreaded shank to provide additional shear strength. These No. 7 x 1-1/4" screws with 16 TPI thread pitch offer optimal performance for both hardwood and softwood applications, with specific drill bit sizing recommendations ensuring proper installation without splitting the wood material.

Specification Summary & Compliance

These wood screws feature a No. 7 screw size with 0.151" thread diameter and 16 threads per inch in a right-hand thread direction. The partially threaded design provides a minimum 3/4" thread length on a 1-1/4" overall length. Manufactured to precise dimensional standards with standard flat head profile and pointed tip for easy starting. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current international safety and environmental standards for industrial and consumer applications.
