S-93406A242 Length 1/2" 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 through the wide truss head design, reducing surface damage and preventing pull-through in sheet metal
• Exceptional thread-forming capability creates permanent, vibration-resistant threads without requiring pre-tapped holes
• Optimized drilling efficiency with precise No. 21 drill bit compatibility (0.159") for clean installations in materials up to 0.025" thickness
• Secure Phillips drive engagement (No. 2 size) prevents cam-out during installation for consistent torque application
• Full-length threading ensures maximum grip length and holding power throughout the entire fastener engagement
• Environmental compliance assurance meets RoHS 3 and REACH standards for sustainable industrial operations

Professional Applications & Engineering Value

This No. 10-12 x 1/2" 18-8 stainless steel Phillips truss head tapping screw delivers exceptional engineering value in sheet metal fabrication applications where vibration resistance and material integrity are critical. The thread forming technology (A/AB type) displaces material rather than removing it, creating stronger threads with superior holding power that won't loosen under dynamic loads. The wide truss head design provides a larger bearing surface that distributes clamping force effectively, preventing distortion of thin sheet metal while maintaining secure fastening. Manufactured from corrosion-resistant 18-8 stainless steel, this fastener maintains structural integrity in demanding environments, making it ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment where reliability is paramount.

Specification Summary & Compliance

This tapping screw features precise No. 10-12 thread specifications with right-hand threading and 12 threads per inch, ensuring proper engagement in sheet metal applications. The fastener is manufactured to industry standards for thread forming screws with Class 2A thread tolerances and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Designed specifically for use with No. 21 drill bits (0.159" diameter) in materials up to 0.025" maximum thickness, this sheet metal fastener delivers reliable performance while meeting stringent industrial compliance requirements.
