S-90930A197 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with black-coated steel construction for long-lasting performance in harsh industrial environments
• Superior thread-forming capability creates permanent, vibration-resistant threads in sheet metal without pre-tapping
• Enhanced driving efficiency with No. 2 Phillips drive for secure installation and reduced cam-out risk
• Increased bearing surface from flanged pan head design distributes load evenly and eliminates need for separate washers
• Optimized sheet metal penetration with pointed tip and 15 TPI thread pitch for smooth insertion and strong holding power
• Full-threaded design maximizes grip length and provides consistent clamping force along the entire fastener
• Regulatory compliance assurance meets RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 8 Phillips pan head tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The black corrosion-resistant coated steel construction provides reliable protection against environmental factors, extending service life in demanding applications. The thread forming design eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating stronger, more durable connections. The A/AB tapping screw specification ensures consistent performance across various sheet metal thicknesses up to 0.025", while the flanged pan head provides excellent bearing surface without washer requirements. This combination of features makes these industrial screws ideal for HVAC systems, electrical enclosures, automotive components, and machinery where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

This No. 8 x 3/4" tapping screw features precise dimensional accuracy with 0.164" thread diameter and 15 TPI thread pitch, manufactured to industry standards for A/AB thread forming screws. The fastener includes a 0.425" flange diameter and requires a No. 29 drill bit (0.136" diameter) for proper installation. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and material safety for industrial applications worldwide.
