S-90190A203 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Exceptional holding power through thread forming technology that creates strong, permanent threads in sheet metal without chips
• Optimized for sheet metal applications with pointed tip and 15 TPI thread design for smooth penetration and secure fastening
• Reliable drive engagement with Phillips No. 2 drive style that prevents cam-out and ensures consistent installation torque
• Maximum material contact from the pan head design that provides a larger bearing surface for enhanced load distribution
• Full threading capability along the entire 1-1/2" length for complete engagement and superior pull-out resistance
• Precision compatibility with standard No. 29 drill bits (0.136" diameter) for efficient installation in 0.025" maximum thickness materials

Professional Applications & Engineering Value

These No. 8 x 1-1/2" zinc-plated steel tapping screws deliver exceptional performance in demanding sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the risk of loose fasteners by creating precise, tight-fitting threads that won't strip or back out under stress. The Phillips pan head design combines easy installation with a low-profile appearance, making these A/AB tapping screws ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment assembly. The fully threaded construction ensures maximum thread engagement throughout the material thickness, providing superior pull-out strength that exceeds conventional fastening methods in thin-gauge metals.

Specification Summary & Compliance

These tapping screws feature precision thread forming with 0.164" thread diameter and 15 TPI thread pitch, manufactured to industry standards for consistent performance. The screws maintain dimensional accuracy with standard Class 2A thread tolerances and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Designed specifically for use with No. 29 drill bits in sheet metal up to 0.025" thickness, these fasteners meet industrial requirements for reliability and regulatory compliance in global markets.
