S-91775A720 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide Steel coating, extending service life in demanding industrial environments.
• Enhanced holding power through thread forming design, creating strong, reliable threads in sheet metal without pre-tapping.
• Streamlined installation with No. 2 Phillips drive and pointed tip, ensuring quick, secure fastening with standard tools.
• Clean, finished appearance thanks to the oval head design, which sits flush with surfaces for professional results.
• Optimized for sheet metal applications with 15 TPI thread pitch and 82° countersink angle, providing maximum grip and vibration resistance.
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting strict environmental and safety requirements for industrial use.
• Precise fit and reduced material stress due to fully threaded shank and standardized dimensions, minimizing the risk of stripping or damage.

Professional Applications & Engineering Value

These No. 8 x 3/4" Phillips Oval Head Thread Forming Tapping Screws are engineered to address common challenges in sheet metal fabrication and assembly. The Black-Oxide Steel construction offers excellent durability against rust and wear, while the thread forming (Type A/AB) design eliminates the need for separate tapping operations, reducing labor time and tooling costs. The oval head provides a low-profile finish that enhances aesthetics and prevents snagging, ideal for enclosures, HVAC systems, and automotive panels. With a No. 2 Phillips drive and pointed tip, these screws ensure easy insertion and high torque resistance, preventing cam-out and improving assembly efficiency in high-volume production settings.
