S-90380A349 Length 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic retention through thread forming design that creates strong, permanent threads without chipping or cracking materials
• Enhanced corrosion resistance with zinc-plated steel construction for reliable performance in various industrial environments
• Optimized drive efficiency with Phillips No. 1 drive that provides secure tool engagement and reduces cam-out during installation
• Complete thread engagement with fully threaded 8mm length and 1.34mm pitch for maximum holding power in plastic assemblies
• Safe material penetration thanks to blunt tip design that minimizes stress concentration and prevents damage to plastic components
• Streamlined installation with standard pan head profile that sits flush while providing ample driving surface
• Precision compatibility with 2.25mm drill bits for accurate hole preparation and optimal thread formation

Professional Applications & Engineering Value

These M3 thread forming screws deliver exceptional value in plastic assembly applications where material integrity is paramount. The TRS thread forming technology displaces plastic material rather than cutting it, creating zero clearance threads that provide vibration resistance and superior pull-out strength. The zinc-plated steel construction ensures durability while the Phillips No. 1 drive offers reliable installation torque transfer. Ideal for plastic assembly in electronics enclosures, automotive components, and consumer products, these screws eliminate the need for inserts while maintaining material structural integrity. The combination of fully threaded design and 1.34mm pitch ensures maximum thread engagement for long-term fastening reliability in demanding applications.
