S-90106A325 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in harsh industrial environments
• Efficient installation through thread forming technology that creates strong, permanent threads without chip removal
• Enhanced load distribution with integrated 0.432" flange that eliminates the need for separate washers
• Maximum driving torque provided by external hex drive design for secure fastening in high-vibration applications
• Self-drilling capability with 9/32" No. 3 drill tip that penetrates up to 0.187" thick materials without pre-drilling
• Complete thread engagement through fully threaded design that ensures consistent holding power along the entire 1-1/4" length
• Regulatory compliance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

This heavy-duty No. 12 flanged tapping screw delivers exceptional engineering value for professionals working with steel, stainless steel, and sheet metal applications. The 410 stainless steel construction provides excellent strength and corrosion resistance, while the thread forming technology creates secure, vibration-resistant connections without generating metal chips that could compromise electrical systems or moving parts. The integrated flange design distributes clamping force evenly, preventing material distortion in thin-gauge applications. With its self-drilling No. 3 tip, this BSD-type screw eliminates separate drilling operations, significantly reducing installation time and labor costs in industrial assembly lines, metal fabrication, and HVAC systems where efficiency and reliability are paramount.

Specification Summary & Compliance

This No. 12 x 1-1/4" flanged tapping screw features precision right-hand threads with 14 TPI and fully threaded design for maximum engagement.
