• Industry compliance assurance meeting RoHS 3 and REACH regulations for safe use across various industrial applications

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws deliver exceptional engineering value through their specialized thread-forming design and integrated sealing washer system. The cutting wings facilitate effortless installation in plastic and wood applications by displacing material rather than removing it, creating stronger thread engagement while preventing material cracking. The conical washer combination of aluminum, rubber, and steel components creates a reliable weather-resistant barrier, making these screws ideal for outdoor construction, electrical enclosures, and marine applications where moisture protection is critical. The dual Phillips/square drive compatibility ensures installation flexibility across different job sites and tool availability scenarios, while the partial threading design concentrates holding power where it's needed most, reducing installation time and improving structural integrity in assembly operations.

Specification Summary & Compliance

These tapping screws feature precise inch system dimensions including No. 12 thread diameter (0.216"), 1-1/4" length with 3/4" minimum thread engagement, and 11 threads per inch configuration. The fasteners maintain right-hand thread direction with partially threaded shank design and pointed tip for optimal penetration. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for industrial and construction applications worldwide.
