S-90610A721 Length 1 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating for extended service life in demanding wood applications
• Enhanced holding power through thread forming technology that creates stronger, more permanent connections in wood materials
• Reduced cam-out and stripped heads with square drive design providing maximum torque transfer during installation
• Optimized pull-out resistance with partial threading design that concentrates holding strength where it matters most
• Precision wood penetration with pointed tip and specific drill bit sizing for both hardwood (3/32") and softwood (5/64") applications
• Flush installation capability with standard flat head profile and 82° countersink angle for smooth, professional finishes
• Reliable performance consistency with right-hand threading and 15 threads per inch ensuring predictable installation behavior

Professional Applications & Engineering Value

These No. 8 wood screws with thread forming technology address critical challenges in wood assembly by eliminating the need for pre-tapped holes while providing superior resistance to vibration loosening. The black-oxide steel construction offers enhanced protection against environmental factors that typically compromise fastener integrity in woodworking and construction applications. The square drive system prevents tool slippage during high-torque installation, reducing installation time and preventing damaged screw heads. With specific drill bit recommendations for both hardwood and softwood, these screws ensure proper thread engagement without splitting the material, making them ideal for furniture manufacturing, cabinetry, deck building, and general construction where reliable, long-term fastening solutions are essential.

Specification Summary & Compliance

These wood screws feature a 0.164" thread diameter with 15 threads per inch and 1" minimum thread length on a 1-1/2" overall length. The thread forming design creates mating threads in wood without cutting, resulting in stronger connections. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and commercial applications while meeting international environmental safety standards.
