S-99512A519 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP30 drive, minimizing cam-out and tool wear for efficient assembly
• Exceptional holding power in plastics thanks to the Tri-Lobe shank design that displaces material to create secure, vibration-resistant threads
• Enhanced corrosion resistance with zinc-plated steel construction, ensuring longevity in various industrial environments
• Reduced installation stress through thread forming (TRS) technology that eliminates chip formation in plastic substrates
• Optimized drive engagement with T30 Torx Plus compatibility, providing reliable performance in high-volume production settings
• Consistent fastening performance with fully threaded 1/4" design and 10 threads per inch, delivering uniform clamping force
• Streamlined assembly process featuring blunt tip and standard pan head for easy alignment and flush mounting

Professional Applications & Engineering Value

These 1/4" TRS tapping screws are specifically engineered to address common challenges in plastic fastening applications where traditional fasteners may strip threads or cause material cracking. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the Torx Plus IP30 drive system ensures maximum torque transfer without cam-out, significantly reducing assembly time and tool replacement costs. The Tri-Lobe shank design creates strong, permanent threads in plastic substrates through cold forming, eliminating chips and providing superior resistance to vibration loosening. This makes them ideal for plastic assembly in automotive components, electrical enclosures, and consumer products where reliable, long-term fastening is critical.

Specification Summary & Compliance

These thread forming screws feature a 1/4" diameter with 10 threads per inch and fully threaded construction for consistent performance. The TRS (Thread Rolling Screw) design follows industry-standard thread forming principles for plastic applications. All components are manufactured to precise dimensional standards and comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest compliance requirements for industrial use.
