Professional Applications & Engineering Value

These No. 10-12 x 3/4" tapping screws deliver exceptional engineering value in sheet metal fabrication and assembly operations. The 18-8 stainless steel composition provides excellent resistance to rust and corrosion, making these thread forming screws ideal for applications exposed to moisture, chemicals, or outdoor elements. The flat undercut head with 82° countersink angle creates a seamless finish that eliminates protrusions in assembled components. As Phillips drive fasteners, they offer reliable installation with standard tools while the thread forming technology eliminates the need for separate tapping operations, reducing assembly time and labor costs. These industrial fasteners are specifically engineered for metal working applications where vibration resistance and permanent thread engagement are critical for structural integrity.

Specification Summary & Compliance

These No. 10-12 x 3/4" tapping screws feature precise inch system dimensions with 0.19" thread diameter and 12 threads per inch. The thread forming (Type A) design follows industry standards for self-tapping applications in sheet metal. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The fully threaded right-hand configuration with pointed tip and round shank cross-section provides consistent performance across industrial applications.
