S-90286A194 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power through thread forming technology that creates strong, permanent threads in sheet metal without chips or debris
• Enhanced installation efficiency with external hex drive design allowing for high torque application and quick installation
• Eliminates separate washers with integrated flange design that provides wider bearing surface and prevents pull-through
• Optimal material engagement with fully threaded pointed tip that ensures smooth starting and complete thread formation
• Precision fit for sheet metal with No. 29 drill bit compatibility and 0.164" thread diameter for secure fastening in thin materials
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe use in regulated industries
• Reliable performance in demanding applications with right-hand threading and 15 threads per inch providing consistent clamping force

Professional Applications & Engineering Value

This No. 8 hex head tapping screw delivers exceptional value in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the need for pre-tapped holes while creating stronger threads through material displacement rather than cutting. This prevents metal chips that could contaminate electrical components or machinery. The flanged design distributes clamping force evenly across a wider surface area, reducing the risk of material deformation in thin gauge metals. With its external hex drive and pointed tip, installation becomes significantly faster while maintaining precise alignment. These industrial fasteners are particularly valuable in HVAC systems, electronic enclosures, and metal fabrication where reliable, vibration-resistant connections are essential for long-term performance.

Specification Summary & Compliance

This thread forming screw features a No. 8-15 thread size with 0.164" diameter and 1/2" length, designed for use with No. 29 drill bit (0.136" diameter) in materials up to 0.025" thickness. The screw meets industry standards for thread forming tapping screws with fully threaded shank and pointed tip configuration. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance for industrial applications worldwide.
