S-90190A239 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping requirements
• Optimized Phillips drive system (No. 2 size) ensures secure tool engagement and reduces cam-out during installation
• Full threading with pointed tip enables faster starts and smoother penetration through sheet metal substrates
• Precision dimensional control with standardized pan head profile for consistent seating and uniform clamp force distribution
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing applications
• Maximum material compatibility designed specifically for 0.025" drilling thickness with No. 21 drill bit pairing

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The zinc-plated steel construction provides reliable corrosion resistance while maintaining high tensile strength for permanent fastening solutions. The thread forming design (Type A/AB) displaces material rather than removing it, creating zero-clearance threads that resist vibration loosening and maintain joint integrity. The Phillips pan head configuration offers excellent drive transfer and a low-profile finish ideal for applications where clearance is limited. These fully threaded screws with pointed tips ensure rapid installation in HVAC systems, electrical enclosures, automotive panels, and industrial equipment where sheet metal fastening reliability is critical.

Specification Summary & Compliance

This tapping screw features precision right-hand threads with 0.19" diameter and 12 threads per inch, conforming to standard thread forming specifications. The pan head design measures 0.373" in diameter with 0.133" height, providing optimal bearing surface. Manufactured to exacting standards for consistent performance in sheet metal applications requiring No. 21 drill bit preparation. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and restricted substance requirements.
