S-90122A333 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated No. 3 drill tip that penetrates up to 0.21" thick aluminum and sheet metal
• Superior corrosion resistance through ultra-corrosion-resistant alloy steel coating for extended service life in harsh environments
• Enhanced load distribution with 0.52" flange diameter providing wider bearing surface and preventing pull-through
• Maximum installation torque achieved through external hex drive design for secure fastening in high-vibration applications
• Complete thread engagement with fully threaded design ensuring consistent holding power along the entire 1-1/2" length
• Reliable thread formation using BSD thread forming technology that creates strong, strip-resistant threads in ductile materials
• Streamlined inventory management with standardized 1/4"-14 thread size compatible with common industrial applications

Professional Applications & Engineering Value

These flanged hex head tapping screws deliver exceptional value in aluminum and sheet metal fabrication where corrosion resistance and installation efficiency are critical. The ultra-corrosion-resistant alloy steel construction withstands environmental exposure in outdoor equipment, electrical enclosures, and HVAC systems. The combination of thread forming technology and integrated drill tip eliminates multiple production steps, reducing labor costs while creating permanent, vibration-resistant connections. The external hex drive ensures high torque application without cam-out, making these BSD tapping screws ideal for automated assembly and maintenance applications requiring reliable fastening in thin-section materials.
