S-94155A211 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping
• Secure square drive system provides maximum torque transfer and reduces cam-out during installation
• Full threading along 1" length ensures consistent holding power throughout the entire engagement
• Optimized pan head design offers low profile clearance while maintaining excellent drive engagement
• Precision-engineered dimensions with No. 4-24 thread specification for reliable performance in 0.086" drill holes
• Environmental compliance assurance meets RoHS 3 and REACH standards for sustainable manufacturing

Professional Applications & Engineering Value

These 18-8 stainless steel thread forming screws deliver exceptional value in sheet metal assembly applications where corrosion resistance and structural integrity are paramount. The A/AB tapping screw type with its pointed tip and right-hand threading creates durable, vibration-resistant connections in materials up to 0.025" thickness without requiring pre-tapped holes. The combination of square drive technology and pan head design ensures reliable installation in confined spaces while preventing stripping. Engineered for use with standard No. 44 drill bits (0.086" diameter), these sheet metal fasteners streamline production processes by eliminating secondary tapping operations, reducing assembly time, and providing consistent clamping force across multiple joining applications in HVAC, electronics enclosures, and industrial equipment manufacturing.

Specification Summary & Compliance

This No. 4-24 x 1" tapping screw features precision Class 2A thread tolerances with 24 threads per inch and fully threaded shank design. Manufactured to industry standards for A/AB thread forming screws, the fastener demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The screw is optimized for 0.086" drill bit size (No. 44) and maximum drilling thickness of 0.025" in sheet metal applications, ensuring reliable performance and regulatory adherence for industrial use.
