S-93406A197 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments.
• 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, secure threads without pre-tapping, saving installation time and labor costs.
• Optimized for sheet metal applications with a maximum drilling thickness of 0.025" and compatibility with No. 29 drill bits.
• Reliable drive engagement provided by the Phillips No. 2 drive, minimizing cam-out and ensuring consistent fastening.
• Full compliance with environmental regulations including RoHS 3 and REACH, ensuring safe and sustainable use in global supply chains.
• Precise thread engagement with 0.164" diameter and 15 TPI right-hand threads for secure fastening in metal assemblies.

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and structural integrity are critical. The thread forming (A/AB type) design eliminates the need for separate tapping operations, creating strong internal threads that resist vibration loosening. The Phillips truss head provides a wider bearing surface than standard heads, distributing clamp force effectively across thin metal surfaces to prevent deformation. This combination of fully threaded construction and pointed tip ensures quick starts and smooth penetration in automated assembly lines, making them ideal for HVAC systems, electronic enclosures, and automotive components where reliability and speed are paramount.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.164" thread diameter and 15 TPI right-hand threads. Features Class 2A thread tolerances for consistent fit and performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use worldwide. The screws are designed for use with No. 29 drill bits (0.136" diameter) and accommodate maximum material thickness of 0.025" in sheet metal applications.
