S-94155A141 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• High-strength fastening for sheet metal up to 0.025" thickness, ensuring reliable, vibration-resistant connections in demanding applications.
• Secure square drive provides excellent torque transmission and reduces cam-out, allowing for tighter installations and improved assembly efficiency.
• Fully threaded shank and pointed tip enable quick, precise starting and maximum thread engagement along the entire length.
• Durable pan head design with standard rounded profile offers a low-profile finish and consistent seating in various sheet metal thicknesses.
• Environmental compliance with RoHS 3 and REACH regulations ensures safe, sustainable use across global industrial supply chains.

Professional Applications & Engineering Value

These thread forming tapping screws are engineered specifically for sheet metal applications where reliability and corrosion resistance are critical. The 18-8 stainless steel composition provides excellent durability against oxidation and chemical exposure, making these fasteners ideal for HVAC systems, electrical enclosures, automotive components, and outdoor equipment. The thread forming technology eliminates the need for separate tapping operations, creating strong, strip-resistant threads that maintain integrity under vibration and load stress. With a No. 10-12 thread pitch and 1-1/2" length, these screws deliver optimal holding power in medium-gauge sheet metal while the square drive ensures efficient installation with standard industrial drivers.

Specification Summary & Compliance

This No. 10 tapping screw features a 0.19" thread diameter with 12 threads per inch and Class 2A thread tolerances for consistent performance. The screw is designed for use with a No. 21 drill bit (0.159" diameter) and accommodates sheet metal up to 0.025" maximum thickness. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory compliance for industrial and commercial applications worldwide.
