S-92400A190 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior pull-out resistance in plastic materials thanks to the innovative Tri-Lobe shank cross-section design
• Eliminates the need for pre-tapping with thread forming technology that creates strong, permanent threads in plastic substrates
• Corrosion-resistant zinc-plated steel construction ensures long-term durability in various industrial environments
• High-torque installation capability with external hex drive and 1/4" hex head for secure fastening applications
• Optimized thread engagement with 0.138" thread diameter and 19 threads per inch for maximum holding power in plastic
• Full 1" threading provides consistent grip along the entire fastener length for enhanced load distribution
• Simplified installation process with compatible No. 32 drill bit size (0.116" diameter) for precise hole preparation

Professional Applications & Engineering Value

These No. 6 zinc-plated steel TRS tapping screws deliver exceptional engineering value in plastic assembly applications where vibration resistance and long-term reliability are critical. The thread forming technology eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, permanent threads that won't strip under stress. The Tri-Lobe shank design provides superior resistance to pull-out forces commonly encountered in plastic components, making these hex head tapping screws ideal for automotive trim, electronic enclosures, and consumer products where plastic fasteners must withstand repeated stress cycles. The combination of right-hand threading and blunt tip design ensures controlled entry and prevents material splitting in delicate plastic substrates.
