S-90395A197 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments
• Effortless installation through A/AB thread forming technology that creates strong, permanent threads without pre-tapping
• Maximum holding power with fully threaded design and 15 TPI precision for superior grip in sheet metal applications
• Quick drive engagement with No. 2 square drive that prevents cam-out and allows for high-torque installation
• Optimized material displacement from pointed tip design that reduces installation force and prevents material cracking
• Reliable regulatory compliance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing
• Versatile pan head profile providing excellent bearing surface and clean finished appearance

Professional Applications & Engineering Value

These No. 8 x 3/4" zinc-plated steel tapping screws deliver exceptional engineering value for sheet metal fabrication and assembly operations. The A/AB thread forming technology eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The fully threaded design with precise 15 TPI spacing ensures maximum engagement throughout the entire fastener length, distributing load evenly and preventing joint failure. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the pointed tip facilitates accurate starting and reduces the risk of cross-threading. These features combine to solve common assembly challenges in HVAC systems, electrical enclosures, and metal furniture manufacturing.

Specification Summary & Compliance

These tapping screws feature a 0.164" thread diameter with 15 TPI precision threading, manufactured to Class 2A thread tolerances for consistent performance. The A/AB thread forming standard ensures reliable thread creation in sheet metal up to 0.025" thickness. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmentally responsible manufacturing and material safety standards. The square drive No. 2 and pan head design adhere to industrial fastener specifications for reliable integration into existing assembly processes.
