S-92400A270 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior pull-out resistance in plastic materials due to the Tri-Lobe shank design that displaces material during installation
• Enhanced corrosion protection with zinc-plated steel construction for reliable performance in various industrial environments
• High-strength thread forming technology creates durable, permanent threads in plastic without pre-tapping
• Easy installation and removal with external hex drive head that provides secure tool engagement and high torque capability
• Optimal material displacement with blunt tip design that prevents plastic cracking during installation
• Full-length threading ensures maximum thread engagement and holding power throughout the entire fastener length
• Flanged head design provides larger bearing surface to prevent pull-through in softer plastic materials

Professional Applications & Engineering Value

These No. 8 TRS tapping screws are specifically engineered for plastic assembly applications where reliable fastening is critical. The thread forming technology combined with the Tri-Lobe shank cross-section creates strong, permanent threads in plastic substrates without generating chips or debris. This design solves common industry challenges of stripping and pull-out failures in plastic components. The zinc-plated steel construction provides essential corrosion resistance for industrial environments, while the external hex drive ensures secure tool engagement during high-torque installation. These screws are ideal for plastic-to-plastic and plastic-to-metal assemblies in automotive, electronics, and consumer product manufacturing where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

These thread forming screws feature precise 0.164" thread diameter with 16 threads per inch and are designed for use with No. 29 drill bit (0.136" diameter). The 1-1/2" length and fully threaded design provide maximum engagement in plastic applications. Manufactured to industry standards for TRS (Thread Rolling Screws) with right-hand threading and Class 2A thread fit. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
