S-99512A634 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T15 Torx drive, minimizing cam-out and tool slippage during installation
• Excellent corrosion resistance from zinc-plated steel construction, ensuring long-term durability in various environments
• Secure, vibration-resistant fastening in plastic materials thanks to the tri-lobe shank design that forms strong threads without chips
• Reliable thread forming performance with TRS (Thread Rolling Screw) design, reducing installation stress and preventing material cracking
• Full-length threading for maximum grip and consistent holding power along the entire 1-1/2" length
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing
• Optimized for plastic assemblies with precise No. 6 size and 19 threads per inch for strong, stripped-resistant connections

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in plastic assembly applications where reliable fastening is critical. The TRS thread forming design with tri-lobe shank cross-section creates permanent, high-strength threads in plastic materials without generating chips or debris that could compromise electronic components or moving parts. This makes them ideal for electronics enclosures, automotive trim, and consumer product assemblies. The T15 Torx drive system provides superior torque transmission compared to Phillips or slotted drives, reducing installation time and preventing damage to screw heads in high-volume production environments. Combined with the zinc plating for corrosion protection, these screws maintain their integrity in both indoor and moderate outdoor applications, ensuring long-term performance in demanding industrial settings.

Specification Summary & Compliance

This No. 6 x 1-1/2" plastic tapping screw features precise dimensional specifications including 0.138" thread diameter, 19 threads per inch, and standard Class 2A thread tolerances for consistent performance. The thread forming (TRS) design follows industry standards for self-tapping fasteners in plastic materials. Manufactured from zinc-plated steel with a blunt tip and fully threaded shank, these screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest restrictions on hazardous substances for global manufacturing applications.
