S-90184A399 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction for extended service life in harsh environments
• Excellent thread-forming capability creates secure, permanent threads in sheet metal without pre-tapping
• Optimized for 0.025" maximum drilling thickness using No. 21 drill bit for precise sheet metal applications
• Phillips pan head design provides reliable drive engagement and a low-profile, rounded finish
• Full threading along 1-3/4" length ensures maximum grip and holding power throughout the fastener
• Right-hand thread direction with 12 threads per inch delivers consistent, reliable fastening performance
• Environmental compliance assurance with RoHS 3 and REACH regulations for responsible manufacturing

Professional Applications & Engineering Value

This 316 stainless steel tapping screw delivers exceptional value in sheet metal fabrication and industrial assembly where corrosion resistance is critical. The thread-forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, reliable threads in sheet metal substrates. The Phillips drive system with No. 2 drive size ensures efficient installation with standard tools, while the pan head profile provides a balanced combination of low-profile appearance and sufficient bearing surface. Engineered for maximum drilling thickness of 0.025" using No. 21 drill bit, this fastener offers predictable performance in automotive, marine, and outdoor equipment applications where exposure to moisture, chemicals, and temperature variations would compromise inferior fasteners.
