S-90190A151 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Effortless installation through thread-forming design that creates strong, permanent threads in sheet metal without pre-tapping
• Enhanced driving efficiency with Phillips No. 2 drive that provides secure bit engagement and reduces cam-out during installation
• Maximum material engagement with fully threaded shank and pointed tip for superior holding power in 0.025" maximum thickness materials
• Optimized thread design featuring 18 threads per inch and 0.138" diameter for reliable performance in sheet metal applications
• Versatile pan head profile with standard rounded design that sits flush while providing ample bearing surface
• Environmental compliance assurance meeting RoHS 3 and REACH standards for responsible manufacturing and global acceptance

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional engineering value in sheet metal applications where vibration resistance and permanent fastening are critical. The thread-forming design eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating stronger, more reliable threads that won't loosen under stress. The Phillips drive system ensures consistent torque application, preventing damage to both the fastener and installation equipment. With full threading and pointed tip, these A/AB type screws provide immediate engagement and maximum thread contact throughout the material thickness, making them ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment where sheet metal integrity must be maintained.
