S-90033A164 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide steel coating, extending service life in demanding industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Precise 82° countersink angle ensures flush mounting with standard sheet metal surfaces for clean, professional finishes.
• Optimized for No. 32 drill bits (0.116" diameter) with maximum 0.025" drilling thickness compatibility, providing reliable performance in thin sheet applications.
• Full threading and pointed tip enable faster starts and consistent engagement throughout the material thickness.
• Phillips No. 2 drive offers widespread tool compatibility and controlled torque application during installation.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and global market acceptability for your products.

Professional Applications & Engineering Value

These No. 6 Phillips flat head tapping screws are specifically engineered for sheet metal assembly applications where reliability and efficiency are paramount. The Black-Oxide steel construction provides essential corrosion protection in industrial environments, while the thread forming (A/AB type) design eliminates the need for separate tapping operations - the screw creates its own perfectly matched threads as it's driven, significantly reducing assembly time and preventing loose connections. The 18 TPI thread pitch and 0.138" thread diameter deliver optimal grip strength in thin materials up to 0.025" thickness. The 82° countersink angle and flat head profile ensure seamless flush mounting, preventing snagging and maintaining aerodynamic or aesthetic surfaces in HVAC, electronics enclosures, automotive components, and machinery panels.

Specification Summary & Compliance

These tapping screws feature inch system measurements with No. 6 screw size, 1-1/4" length, and fully threaded right-hand orientation. The manufacturing follows standard A/AB tapping screw specifications with precise thread forming capability. Compliance is verified with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current international standards for restricted substances and chemical safety in industrial applications.
