S-99512A636 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T15 Torx drive prevents cam-out and tool slippage during installation
• Secure fastening in plastic materials through TRS thread forming design that creates strong, permanent threads without pre-drilling
• Excellent corrosion resistance provided by zinc-plated steel construction for extended service life in various environments
• Enhanced driving stability with tri-lobe shank cross-section that resists rotation during installation
• Maximum holding power achieved through fully threaded design along the entire 2" length
• Streamlined assembly process with blunt tip and standardized pan head profile for quick, consistent installation
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

These No. 6 x 2" zinc-plated steel tapping screws deliver exceptional performance in plastic assembly applications where traditional fastening methods often fail. The TRS thread forming design eliminates the need for pre-drilled tapping holes, as the tri-lobe shank displaces plastic material to create strong, load-bearing threads that won't strip or loosen under vibration. 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. Engineered specifically for plastic materials, these screws maintain structural integrity while preventing cracking or stress concentration in delicate polymer components, making them ideal for electronics enclosures, automotive trim, and consumer products where reliable fastening is critical.

Specification Summary & Compliance

These thread forming screws feature precise 0.138" thread diameter with 19 threads per inch and right-hand threading throughout the entire 2" length. The standard pan head configuration measures 0.27" in diameter with 0.097" height, compatible with 1/8" drill bits for pilot holes when required. Manufactured to industry standards for tapping screws in plastic applications, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest requirements for hazardous substance restrictions in industrial and consumer products.
