S-90930A520 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Effortless installation through thread forming technology that creates strong, permanent threads without pre-tapping
• Maximum holding power with fully threaded design ensuring complete engagement along the entire fastener length
• Enhanced stability from the integrated flange design that provides wider bearing surface and prevents over-tightening
• Optimized for sheet metal applications with pointed tip and specific thread design for clean penetration up to 0.025" thickness
• Reliable driving performance with Phillips No. 2 drive that resists cam-out and ensures consistent torque application
• Industry compliance assurance meeting RoHS 3 and REACH environmental standards for global manufacturing applications

Professional Applications & Engineering Value

These No. 8 x 1-1/4" zinc-plated steel 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, vibration-resistant connections. The Phillips drive configuration ensures reliable torque transfer without specialized tools, making them ideal for high-volume production environments. The zinc-plated steel construction provides essential corrosion protection for both indoor and moderate outdoor applications, while the flanged pan head design distributes clamping force evenly, preventing material distortion in thin-gauge metals. These A/AB tapping screws are engineered to solve common fastening challenges in HVAC systems, electrical enclosures, and metal furniture assembly where reliable, permanent connections are critical.

Specification Summary & Compliance

These tapping screws feature precise 0.164" thread diameter with 15 threads per inch and right-hand threading conforming to standard industrial specifications. The fully threaded design ensures maximum engagement, while the No. 29 drill bit size (0.136" diameter) compatibility simplifies installation planning. Manufactured to exacting standards, these screws demonstrate compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and suitability for global supply chains. The combination of thread forming technology and precise dimensional control guarantees consistent performance across production runs.
