S-94065A157 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Secure tamper-resistant installation with drilled spanner drive that requires special tools, preventing unauthorized removal
• Maximum material compatibility with 0.025" maximum drilling thickness, perfect for standard sheet metal applications
• Full-length threading ensures consistent grip along the entire 1-1/2" length for uniform clamping force
• Optimized pan head design provides a low-profile finish with standard rounded profile for smooth surface integration
• Environmental compliance assurance meets RoHS 3 and REACH regulations for safe, sustainable manufacturing

Professional Applications & Engineering Value

This No. 6-18 sheet metal tapping screw delivers exceptional engineering value in industrial fastening applications where corrosion resistance and secure installation are critical. The 18-8 stainless steel construction prevents rust and degradation in demanding environments, while the thread forming A/AB type design eliminates the need for separate tapping operations in sheet metal up to 0.025" thickness. The drilled spanner drive provides tamper-resistant security, making these fully threaded screws ideal for HVAC systems, electronic enclosures, and machinery panels where vibration resistance and unauthorized access prevention are essential. The combination of right-hand threading and pointed tip ensures quick starts and smooth penetration, reducing installation time and improving production efficiency in high-volume manufacturing settings.
