S-90054A146 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in industrial environments
• Enhanced driving efficiency with combined external hex/slotted drive for versatile tool compatibility and secure installation
• Reliable thread forming capability that creates strong, permanent threads in sheet metal without pre-tapping
• Increased bearing surface from the integrated flange design, distributing load evenly and preventing pull-through
• Full threading along the entire 3/8" length ensures maximum grip and holding power in thin materials
• Precision-engineered tip with pointed design facilitates easy starting and reduces installation effort
• Optimized for 0.025" maximum drilling thickness with No. 32 drill bit compatibility for precise sheet metal applications

Professional Applications & Engineering Value

These No. 6-18 thread forming tapping screws deliver exceptional performance in sheet metal assembly applications where vibration resistance and permanent fastening are critical. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the hex flange design eliminates the need for separate washers, streamlining installation and reducing component count. The A/AB tapping screw type with thread forming technology creates strong, clean threads in sheet metal without generating chips, preventing contamination in sensitive assemblies. The combination of external hex/slotted drive offers flexibility for both power and manual tool applications, making these flange screws ideal for HVAC systems, electronic enclosures, and automotive components where reliable, vibration-resistant fastening is paramount.
