S-90286A153 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power with flanged design that distributes load evenly and prevents pull-through in sheet metal applications
• Efficient thread forming technology creates precise mating threads without chips, eliminating tapping operations and reducing assembly time
• Full-length threading with pointed tip ensures quick starts and smooth penetration into pre-drilled No. 32 holes (0.116" diameter)
• External hex drive with 1/4" head width provides secure tool engagement for high-torque installation using standard wrenches
• Right-hand thread direction with 18 TPI pitch delivers reliable fastening performance in standard industrial applications
• Maximum material compatibility with RoHS 3 and REACH compliance, ensuring environmental regulation adherence for global supply chains
• Optimized for 0.025" maximum drilling thickness in sheet metal, providing reliable performance in thin-gauge material applications

Professional Applications & Engineering Value

These No. 6-18 hex head tapping screws deliver exceptional value in sheet metal assembly where vibration resistance and pull-out strength are critical. The thread forming design creates permanent, high-strength threads in ductile materials without generating chips that could cause electrical shorts or contamination. The flanged head eliminates the need for separate washers while providing increased bearing surface, preventing surface damage and maintaining clamp load under dynamic conditions. With 0.138" thread diameter and fully threaded construction, these industrial fasteners ensure maximum engagement in pre-drilled holes, making them ideal for HVAC systems, electronic enclosures, automotive components, and machinery where reliable self-tapping performance is essential.

Specification Summary & Compliance
