S-90380A296 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
• Excellent thread retention in plastic due to the TRS thread forming design, which creates strong, permanent threads without chipping or cracking the material.
• High torque transmission and reduced cam-out with the Phillips No. 2 drive, providing reliable and efficient installation.
• Enhanced holding power and vibration resistance from the tri-lobe shank and fully threaded design, preventing loosening over time.
• Wide compatibility and easy installation using a standard No. 23 drill bit (0.154" diameter), streamlining assembly processes.
• Secure and flush fastening with the rounded pan head profile, offering a clean finish and improved load distribution.
• Compliance with global environmental and safety standards including RoHS 3 and REACH, ensuring safe use in various industrial applications.

Professional Applications & Engineering Value

These No. 8 x 1-1/4" zinc-plated steel TRS tapping screws are specifically engineered for plastic applications, where traditional fasteners often fail. The thread forming method and tri-lobe shank cross-section displace material without cutting, which eliminates chips and reduces stress concentration. This design prevents stripping and cracking in plastic components, common issues with standard machine screws. The Phillips drive ensures quick, secure installation with common tools, while the zinc plating provides a protective barrier against corrosion, extending service life in humid or outdoor settings. Ideal for electronics enclosures, automotive trim, and consumer appliances, these screws deliver reliable performance and reduce assembly time and costs.

Specification Summary & Compliance

This product features a No. 8 screw size with a 0.164" thread diameter and 16 threads per inch, ensuring precise fit and Class 2A thread tolerance for consistent performance. The TRS (Thread Rolling Screw) type adheres to common industrial standards for thread forming fasteners. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and supporting safe, sustainable manufacturing practices.
