S-90417A115 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the Tri-Lobe shank design that displaces material during installation
• Enhanced corrosion resistance provided by the Black-Oxide Steel finish for extended service life in various environments
• Efficient thread forming technology creates strong, permanent threads in plastic without generating chips
• Secure installation and reduced cam-out with the Phillips No. 1 drive system for reliable fastening
• Precision threading with 24 TPI ensures tight, vibration-resistant connections in plastic assemblies
• Optimized for plastic applications with blunt tip design that prevents material damage during installation
• Full 1-inch threading coverage provides maximum engagement strength throughout the fastener length

Professional Applications & Engineering Value

These No. 3 TRS tapping screws deliver exceptional performance in plastic fastening applications where traditional fasteners fail. The thread forming technology combined with the Tri-Lobe shank cross-section creates high-strength, strip-resistant threads in plastic substrates without the risk of material cracking or stress concentration. The Black-Oxide Steel construction provides essential corrosion protection for industrial environments while maintaining the structural integrity needed for demanding applications. Engineered specifically for plastic installation, these screws eliminate the need for additional tapping operations, reducing assembly time and labor costs in manufacturing processes involving plastic components, enclosures, and assemblies.

Specification Summary & Compliance

These thread forming tapping screws feature precision 0.099" thread diameter with 24 threads per inch and fully threaded design for maximum holding strength. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial safety and environmental standards. The TRS (Thread Rolling Screw) design with right-hand threading and standard pan head profile provides reliable performance in plastic materials when used with the recommended No. 43 drill bit (0.089" diameter) for proper hole preparation.
