S-90190A192 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs
• Optimized torque transfer through Phillips No. 2 drive design prevents cam-out and ensures secure fastening during high-torque applications
• Maximum material penetration with fully threaded shank and pointed tip design for superior holding power in sheet metal assemblies
• Precision thread engagement with 15 TPI configuration provides reliable, vibration-resistant connections in thin materials
• Versatile compatibility with standard No. 29 drill bits (0.136" diameter) for quick installation in materials up to 0.025" thickness
• Regulatory compliance assurance meets RoHS 3 and REACH standards for global industrial applications and supply chain requirements

Professional Applications & Engineering Value

These No. 8 x 3/8" zinc-plated steel tapping screws deliver exceptional engineering value in sheet metal applications where reliable fastening is critical. The thread forming technology eliminates the need for separate tapping operations, significantly reducing assembly time and costs while creating stronger, more durable connections than traditional cutting screws. The A/AB screw type with 15 TPI precision threading ensures optimal material displacement in thin gauge metals, preventing stripping and maintaining joint integrity under vibration and dynamic loads. The combination of zinc-plated corrosion resistance and Phillips drive compatibility makes these screws ideal for HVAC systems, electrical enclosures, automotive components, and industrial machinery where environmental factors and production efficiency are paramount concerns for engineering teams.
