S-93406A106 Length 1/4" 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
• Enhanced holding power from the wide truss head design, distributing load effectively and preventing pull-through in thin materials
• Efficient thread-forming capability for secure fastening without pre-tapped holes, reducing installation time and tooling costs
• Reliable drive engagement with Phillips No. 1 drive, minimizing cam-out and ensuring consistent torque application
• Full threading for maximum grip along the entire length, providing uniform clamping force in sheet metal up to 0.025" thickness
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industrial applications
• Optimized for sheet metal with precise thread diameter and pointed tip, facilitating easy insertion and reducing material stress

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are engineered to address common challenges in sheet metal fastening, such as material fatigue and corrosion. The thread-forming design eliminates the need for separate tapping operations, streamlining assembly processes in HVAC, electronics enclosures, and automotive panels. With a wide truss head, they provide a larger bearing surface to prevent sinking into soft or thin materials, enhancing joint integrity. The fully threaded and right-hand thread configuration ensures uniform stress distribution, reducing the risk of stripping in applications requiring high vibration resistance. Made from durable 18-8 stainless steel, these screws offer excellent strength and longevity, even in moist or chemical-exposed environments, making them a cost-effective solution for industrial maintenance and production lines.

Specification Summary & Compliance
