S-90286A148 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with 1/4" external hex drive for reliable installation and removal in high-vibration environments
• Efficient thread forming capability creates permanent, secure threads in sheet metal without requiring pre-tapped holes
• Integrated flange design eliminates the need for separate washers while providing enhanced load distribution
• Optimized drill compatibility with No. 32 drill bit (0.116") and 0.025" maximum drilling thickness for precise installation
• Full threading with pointed tip ensures smooth engagement and maximum thread contact for superior holding power
• Comprehensive regulatory compliance meets RoHS 3 and REACH standards for safe use in industrial applications
• Right-hand threading configuration provides standard installation familiar to maintenance and assembly teams

Professional Applications & Engineering Value

These No. 6-18 thread forming tapping screws are specifically engineered for sheet metal applications where traditional fastening methods fall short. The flanged hex head design combines the installation efficiency of an external hex drive with the load-bearing benefits of an integrated washer, eliminating component count while maintaining structural integrity. The thread forming tapping method creates strong, permanent threads in ductile materials without generating chips, making them ideal for electrical enclosures, HVAC systems, and automotive panels where debris contamination must be avoided. The fully threaded configuration with pointed tip ensures maximum engagement throughout the material thickness, providing exceptional pull-out resistance in thin-section applications where joint reliability is critical.

Specification Summary & Compliance

This No. 6-18 x 1/2" flanged hex head tapping screw features a 0.138" thread diameter with 18 threads per inch in right-hand orientation. Manufactured to precise dimensional standards with Class 2A thread tolerances for consistent performance. The screw is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and chemical restriction adherence. Designed for use with No. 32 drill bits (0.116" diameter) and suitable for maximum drilling thickness of 0.025" in sheet metal applications.
