S-93406A156 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction for long-lasting performance in harsh environments
• Enhanced fastening stability from the wide truss head design that distributes load over a larger surface area
• Efficient thread forming technology creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Optimized installation process with Phillips No. 2 drive and pointed tip for quick, secure fastening in 0.025" maximum thickness materials
• Full-threaded design ensures maximum grip length and superior holding power throughout the entire fastener length
• Precise drilling compatibility with No. 32 drill bit (0.116" diameter) for accurate hole preparation and secure fit
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable industrial use

Professional Applications & Engineering Value

This No. 6-18 thread forming tapping screw delivers exceptional engineering value for sheet metal applications where corrosion resistance and structural integrity are paramount. The 316 Stainless Steel composition provides superior protection against chemical exposure and atmospheric corrosion, making it ideal for marine, chemical processing, and outdoor equipment. The thread forming technology eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that won't loosen under stress. The wide truss head design offers increased bearing surface, preventing pull-through in thin gauge materials while the Phillips drive ensures efficient installation with standard tools. These tapping screws solve critical fastening challenges in HVAC systems, electronic enclosures, and industrial machinery where reliable, permanent connections in sheet metal are essential.

Specification Summary & Compliance
