S-91087A130 1/4"-20 x 2 1/4" Wood Screws

Key Features & Benefits at a Glance

• Superior torque transfer with T30 Torx drive that minimizes cam-out for faster, more secure installations
• Enhanced corrosion resistance through black-phosphate steel coating for extended service life in demanding environments
• Optimal material grip with UNC coarse threading that provides excellent holding power in wood and sheet metal
• Clean, flush finishes enabled by the 82° countersink angle and flat head design for professional-looking results
• Reduced splitting risk through partial threading that concentrates gripping power where needed most
• Reliable thread formation with thread-forming design that creates strong, permanent connections without pre-tapping
• Environmental compliance assurance meeting RoHS 3 and REACH standards for responsible manufacturing

Professional Applications & Engineering Value

These 1/4-20 UNC Torx flat head wood screws deliver exceptional engineering value for wood and sheet metal applications where vibration resistance and long-term reliability are critical. The black-phosphate steel construction provides superior corrosion protection in environments where moisture or chemical exposure might compromise ordinary fasteners. The T30 Torx drive system eliminates the frustrating cam-out issues common with Phillips drives, allowing for higher torque application and reducing installation time. The partially threaded design ensures maximum clamping force by preventing thread engagement in non-critical sections, while the 82° countersink angle creates seamless, professional finishes in cabinetry, furniture, and structural wood assemblies. These thread-forming screws eliminate the need for separate tapping operations, streamlining production processes in manufacturing and construction settings.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 1/4"-20 UNC coarse threads following standard thread class tolerances. The thread-forming tapping method ensures consistent performance across applications. These screws feature a standard flat head profile with 2-1/4" length and partial threading extending 1-1/2" minimum. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions.
