S-93406A414 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and long-term reliability.
• Enhanced load distribution from the wide truss head design, reducing the risk of material pull-through in thin sheet metal.
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping, speeding up assembly.
• Secure, cam-out resistant driving with the No. 3 Phillips drive, ensuring consistent torque application and reduced tool slippage.
• Full threading along the 1-3/4" length provides maximum grip and holding power across the entire fastened material thickness.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global manufacturing standards.
• Optimized for 5.5mm drill bits and 0.025" maximum drilling thickness, offering precise fit and reliable performance in standard sheet metal applications.

Professional Applications & Engineering Value

These No. 14 x 1-3/4" Phillips Truss Head Tapping Screws are engineered to address common challenges in sheet metal assembly, such as material stripping and corrosion-induced failure. The 18-8 Stainless Steel material provides excellent resistance to rust and oxidation, making these screws suitable for outdoor, marine, or high-moisture industrial settings. The thread forming (Type A/AB) design displaces material to form robust internal threads, eliminating the need for separate tapping operations and reducing installation time. The wide truss head offers a larger bearing surface, distributing clamp load effectively to prevent deformation in thin-gauge metals. This combination of corrosion-resistant properties and efficient thread forming technology ensures reliable, vibration-resistant fastening in HVAC, automotive, and electronics enclosures, enhancing both assembly speed and long-term structural integrity.
