S-93406A249 Length 1 1/4" 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 thanks to the wide truss head design that reduces surface pressure and prevents material damage
• Excellent holding power through thread forming technology that creates strong, permanent threads in sheet metal without pre-tapping
• Secure and efficient installation with No. 2 Phillips drive that minimizes cam-out and ensures consistent torque application
• Optimized for sheet metal applications with pointed tip and fully threaded design for quick starting and maximum thread engagement
• Reliable performance in thin materials with capability to drill through up to 0.025" thickness using No. 21 drill bit
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe use across global markets

Professional Applications & Engineering Value

This 18-8 stainless steel tapping screw delivers exceptional value in sheet metal fastening applications where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for separate tapping operations, creating strong, permanent threads that won't strip or loosen under vibration. The wide truss head provides superior load distribution across a larger surface area, preventing pull-through in thin gauge materials while the No. 2 Phillips drive ensures secure installation with standard tools. Ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment, this A/AB type tapping screw offers reliable performance in demanding environments where corrosion resistant fasteners are essential for long-term durability and maintenance reduction.
