S-93406A140 Length 3/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments
• Enhanced load distribution from the wide truss head design, reducing surface damage and preventing pull-through in sheet metal applications
• Efficient thread forming technology creates strong, permanent threads without chips, eliminating the need for pre-tapped holes
• Secure Phillips No. 2 drive engagement provides reliable torque transfer and reduces cam-out during installation
• Full threading and pointed tip enable quick starts and maximum thread engagement for superior holding power in thin materials
• Precision compatibility with No. 32 drill bits (0.116" diameter) for optimal performance in sheet metal up to 0.025" thickness
• Environmental compliance assurance with RoHS 3 and REACH regulations, meeting strict industrial safety standards

Professional Applications & Engineering Value

This No. 6 x 3/16" 18-8 stainless steel Phillips truss head tapping screw is engineered specifically for demanding sheet metal applications where material integrity and fastener reliability are critical. The thread forming technology (A/AB type) creates precise mating threads through material displacement rather than cutting, resulting in stronger connections and eliminating chip-related contamination in sensitive assemblies. The wide truss head design provides exceptional bearing surface, distributing clamping force effectively to prevent distortion in thin-gauge materials. With 18 TPI fine threading and full thread engagement, this fastener delivers maximum pull-out resistance in applications ranging from HVAC systems and electrical enclosures to automotive components and industrial machinery where vibration resistance and corrosion protection are essential.

Specification Summary & Compliance

This sheet metal tapping screw features precision 0.138" thread diameter with 18 threads per inch and 3/16" length, manufactured to standard thread forming specifications for consistent performance. The right-hand threaded design with pointed tip ensures easy starting and proper alignment. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and industrial suitability, while the 18-8 stainless steel construction provides excellent mechanical properties and corrosion resistance for long-term service life.
