Professional Applications & Engineering Value

These No. 10 wood screws are engineered specifically for demanding woodworking and construction applications where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition provides exceptional durability against environmental factors, making these flat head Phillips screws ideal for outdoor furniture, decking, and marine applications. The thread forming design eliminates the need for separate tapping operations while creating stronger thread engagement in both hardwood and softwood materials. The partially threaded configuration concentrates holding power where it matters most, preventing wood splitting while maintaining superior pull-out resistance. With precise 82° countersink angle and Phillips No. 2 drive, these screws ensure flush mounting and efficient installation in high-volume production environments.

Specification Summary & Compliance

These wood screws feature a No. 10 screw size with 3-1/2" length and 0.19" thread diameter at 13 threads per inch. The flat head profile measures 0.385" in diameter with standard configuration, while the partial threading extends to a minimum of 2.333". Manufacturing complies with industry standards for thread forming screws and includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial and commercial applications.
