S-93406A107 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life
• Enhanced load distribution from the wide truss head design, reducing material stress and preventing pull-through in thin sheet metal
• Reliable, vibration-resistant fastening using thread forming technology that creates strong, precise threads without generating chips
• Streamlined installation process with a No. 1 Phillips drive and pointed tip for quick starting and reduced assembly time
• Consistent performance in sheet metal up to 0.025" thick, ensuring secure fastening when used with the recommended No. 44 drill bit
• Compliance with major environmental regulations including RoHS 3 and REACH, making it suitable for global industrial supply chains
• Full threading for maximum grip length, providing superior holding power across the entire 1/4" length in your application

Professional Applications & Engineering Value

This 316 stainless steel tapping screw delivers exceptional value in sheet metal assembly applications where corrosion resistance and joint integrity are paramount. The thread forming design eliminates chip generation, preventing contamination in sensitive equipment while creating stronger threads through material displacement. The Phillips truss head provides a larger bearing surface, distributing clamp load effectively to prevent distortion in thin gauge materials. Engineered for No. 4-24 threading with a pointed tip, it ensures quick alignment and reduces installation effort. These features combine to solve common industrial challenges including vibration loosening, material fatigue, and corrosion-induced failure in HVAC, electronic enclosures, and automotive components.
