S-90065A044 Length 1/8" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel ensures long-lasting performance in demanding environments, reducing replacement costs and maintenance downtime.
• Thread forming (Type AB) design creates strong, secure threads in sheet metal without pre-tapping, speeding up assembly and improving pull-out resistance.
• 82° countersink angle with undercut flat head provides a flush, professional finish that minimizes snagging and enhances aesthetic appeal in visible applications.
• Fully threaded shank and pointed tip allow for easy starting and maximum thread engagement in materials up to 0.025" thick, ensuring reliable fastening.
• No. 0 Phillips drive offers common tool compatibility and controlled torque application, reducing cam-out risks and installation errors.
• Precise 42 threads per inch and 0.073" diameter deliver excellent holding power in thin sheet metal, preventing stripping and vibration loosening.
• RoHS 3 and REACH compliance guarantees environmental and safety standards are met, supporting sustainable and responsible manufacturing practices.

Professional Applications & Engineering Value

These No. 1 Phillips flat head tapping screws are specifically engineered for sheet metal assemblies where reliability and efficiency are critical. Made from 18-8 stainless steel, they resist corrosion from moisture, chemicals, and outdoor exposure, making them ideal for HVAC, electronics enclosures, and automotive panels. The thread forming (Type AB) tapping method eliminates the need for separate tapping operations, reducing labor time and tooling costs while creating strong, load-bearing threads that resist vibration fatigue. The undercut flat head design ensures a smooth, flush finish that prevents interference in tight spaces and improves aerodynamic profiles. With a pointed tip and full threading, these screws drive easily into pre-drilled holes (using a No. 52 drill bit) and maintain grip in thin materials up to 0.025", addressing common issues like material cracking and loose fasteners in lightweight structures.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.073", length of 1/8", and 42 threads per inch, ensuring precise fit in sheet metal applications. The flat head features an 82° countersink angle and undercut profile for seamless installation. Manufacturing and material compliance include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of restricted hazardous substances and supporting global supply chain requirements. The screws are designed for use with a No. 52 drill bit (0.0635" diameter) and are fully threaded with a right-hand direction for consistent performance.
