S-90198A713 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh chemical and marine environments
• Flush, secure installation thanks to the flat head design and standard 82° countersink angle for seamless sheet metal surfaces
• Efficient thread-forming capability creates strong, permanent threads in sheet metal without pre-tapping
• Reliable driving performance with Phillips No. 3 drive for controlled torque application and reduced cam-out risk
• Full threading along the 3/4" length ensures maximum grip and uniform load distribution in thin materials
• Precision dimensional compliance with standard inch measurements and consistent 10 threads per inch for reliable mating
• Environmental regulation compliance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These 316 stainless steel tapping screws are specifically engineered for sheet metal applications where corrosion resistance and structural integrity are critical. The thread forming design eliminates the need for separate tapping operations, reducing installation time and preventing loose fittings in thin-gauge materials. The flat head profile with 82° countersink provides a smooth, flush finish that prevents snagging and maintains aerodynamic surfaces in HVAC systems, electronic enclosures, and automotive panels. With fully threaded shanks and precise No. 14 screw size, these fasteners distribute clamping force evenly across the entire engagement length, preventing material distortion in assemblies up to 0.025" thickness. The combination of 316 stainless steel material and Phillips drive style makes these screws ideal for maintenance-free applications in chemical processing, marine equipment, and food processing machinery where moisture and corrosive agents are present.
