S-90065A300 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Excellent thread retention and vibration resistance due to the thread forming (Type A) design, which creates strong, secure threads in sheet metal without pre-tapping.
• Flush, professional finish achieved with the standard flat head and 82° countersink angle, preventing snagging and providing a smooth surface.
• Efficient installation with a No. 3 Phillips drive, allowing for high torque application and reducing the risk of cam-out.
• Full threading for maximum grip length, ensuring a secure hold along the entire 1-3/4" length in sheet metal up to 0.025" thickness.
• Reliable dimensional consistency with a No. 12 screw size and 0.216" thread diameter, ensuring predictable performance and interchangeability.
• Compliance with major environmental regulations including RoHS 3 and REACH, making them suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are engineered to solve common fastening challenges in sheet metal applications. The thread forming (Type A) design displaces material to create strong, clean internal threads, eliminating the need for a separate tapping operation and reducing assembly time and cost. This is particularly valuable in high-volume production environments. The fully threaded shank and pointed tip ensure easy starting and a uniform distribution of clamping force, which helps prevent loosening under vibration—a critical factor in automotive, electronics enclosures, and HVAC assemblies. The combination of the corrosion-resistant 18-8 stainless steel material and the 82° flat head profile makes these Phillips drive screws a durable and reliable choice for both indoor and outdoor industrial equipment.

Specification Summary & Compliance
