S-93406A199 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Enhanced load distribution from the wide rounded truss head design, reducing surface damage and pull-through
• Secure, vibration-resistant fastening through thread forming technology that creates strong, permanent threads in sheet metal
• Efficient installation with No. 2 Phillips drive, allowing for quick, high-torque application without cam-out
• Maximum material compatibility with fully threaded, pointed tip design for easy starting and consistent engagement
• Reliable performance in thin materials, designed for sheet metal up to 0.025" thickness with No. 29 drill bit compatibility
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These No. 8 x 1" Phillips Truss Head Tapping Screws deliver exceptional engineering value in sheet metal fabrication and assembly operations. The 18-8 stainless steel composition provides excellent corrosion resistance for outdoor equipment, electrical enclosures, and HVAC systems where environmental exposure is a concern. The thread forming (A/AB type) design eliminates the need for pre-tapped holes, creating stronger thread engagement by displacing material rather than removing it. This prevents metal chips in sensitive assemblies while providing superior vibration resistance. The wide truss head profile distributes clamping force over a larger area, preventing distortion in thin-gauge materials and maintaining structural integrity in demanding applications.
