Professional Applications & Engineering Value

These 316 stainless steel oval head tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger thread engagement in materials up to 0.025" thickness. The corrosion-resistant properties of 316 stainless steel make these Phillips drive screws ideal for applications exposed to moisture, chemicals, or outdoor elements, including HVAC systems, electrical enclosures, and industrial equipment. The oval head profile with 82° countersink angle provides a smooth, finished appearance while preventing snagging and ensuring proper seating in prepared holes.
