S-93406A312 Length 5/8" 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 rounded truss head design, reducing surface damage and material stress
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping requirements
• Secure fastening with No. 3 Phillips drive providing excellent torque transmission and reduced cam-out risk
• Full threading and pointed tip ensure quick starts and consistent engagement throughout the entire 5/8" length
• Optimized for 0.025" maximum drilling thickness with precise 0.242" thread diameter and 10 threads per inch for reliable sheet metal applications
• Regulatory compliance assurance with RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

This No. 14 Phillips truss head tapping screw delivers exceptional engineering value for sheet metal applications where vibration resistance and material integrity are critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making it ideal for outdoor equipment, HVAC systems, and electronic enclosures exposed to moisture or chemicals. The thread forming A/AB tapping screw design creates stronger thread engagement by displacing material rather than removing it, eliminating chip-related contamination issues in sensitive assemblies. The wide truss head profile distributes clamping force over a larger surface area (0.557" diameter), preventing pull-through in thin gauge materials while the fully threaded design ensures maximum holding power across the entire fastener length. This combination of features solves common industrial challenges including material fatigue, corrosion-induced failure, and installation efficiency in high-volume manufacturing environments.

Specification Summary & Compliance
