S-93406A151 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 through wide truss head design that resists pull-through in thin sheet metal applications
• Reliable installation efficiency with No. 2 Phillips drive that prevents cam-out during high-torque applications
• Strong thread-forming capability with A/AB tapping screw design that creates secure, permanent threads without pre-tapping
• Maximum material penetration through fully threaded design and pointed tip for consistent holding power throughout the fastener length
• Optimal material compatibility with precise No. 32 drill bit size (0.116" diameter) recommendation for clean installations in materials up to 0.025" thickness
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

This No. 6-18 Phillips Truss Head tapping screw delivers exceptional engineering value in sheet metal fabrication and assembly applications. The 18-8 stainless steel composition provides excellent corrosion resistance, making it ideal for outdoor equipment, electrical enclosures, and HVAC systems where environmental exposure is a concern. The thread forming design (Type A/AB) creates strong, permanent threads in pre-drilled holes without requiring tapped threads, significantly reducing installation time and labor costs. The wide truss head profile distributes clamping force over a larger surface area, preventing material deformation in thin gauge metals up to 0.025" thickness. This combination of corrosion-resistant material and optimized thread forming technology solves common challenges of strip-out, vibration loosening, and environmental degradation in demanding industrial settings.

Specification Summary & Compliance

This tapping screw features precise inch system dimensions: No. 6-18 thread (0.138" diameter, 18 TPI) with 3/4" length and Class 2A thread tolerances. The right-hand threaded, fully threaded design ensures consistent engagement throughout the fastener. Manufacturing complies with industry standards for A/AB tapping screw types and includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for use in regulated industries and international markets.
