S-93406A411 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Enhanced fastening stability from the wide truss head design, distributing load over a larger surface area
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping
• Maximum driving efficiency with No. 3 Phillips drive, reducing cam-out and tool slippage
• Full-length threading ensures consistent holding power along the entire 5/8" length
• Compliance with environmental regulations including RoHS 3 and REACH for safe, sustainable operations
• Optimized for sheet metal applications with pointed tip for easy starting and secure fastening

Professional Applications & Engineering Value

These No. 12 Phillips truss head tapping screws are engineered specifically for demanding sheet metal applications where vibration resistance and long-term reliability are critical. The 18-8 stainless steel construction provides excellent corrosion resistance, making them suitable for outdoor equipment, HVAC systems, and industrial machinery exposed to moisture or chemicals. The thread forming design eliminates the need for separate tapping operations, creating strong, clean threads that won't strip or loosen under stress. The wide truss head distributes clamping force effectively, preventing pull-through in thin materials while the No. 3 Phillips drive ensures secure tool engagement during installation. These fully threaded fasteners deliver maximum holding power across the entire engagement length, making them ideal for securing panels, brackets, and assemblies in manufacturing and metalworking applications.

Specification Summary & Compliance

This thread forming sheet metal screw features a No. 12 size with 0.216" thread diameter and 11 threads per inch, manufactured to standard inch measurements. The fastener meets industry standards for A/AB tapping screw type specifications and includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The truss head design provides a 0.511" diameter contact surface with 0.134" head height, optimized for secure fastening in sheet metal applications requiring 3/16" drill preparation.
