S-99512A259 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transfer with Torx Plus IP15 drive that minimizes cam-out and tool slippage during installation
• Excellent corrosion resistance provided by zinc-plated steel construction for extended service life in various environments
• Optimal thread engagement with Tri-Lobe shank design that creates strong, vibration-resistant connections in plastic materials
• Reduced installation stress through thread forming technology that eliminates chips and prevents material cracking
• Enhanced driving efficiency with standardized pan head design that allows for flush mounting and consistent seating
• Reliable performance with 19 threads per inch configuration that ensures secure fastening in plastic assemblies
• Environmental compliance meeting RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

These No. 6 TRS thread forming screws are specifically engineered to address common challenges in plastic assembly applications where traditional fasteners often cause material stress or failure. The Tri-Lobe shank cross-section and thread forming design work synergistically to displace plastic material without creating chips, eliminating the risk of contamination while generating strong, permanent threads that resist vibration loosening. The zinc-plated steel construction provides essential corrosion protection for applications exposed to moisture or harsh environments, while the Torx Plus IP15 drive system ensures maximum torque transfer with minimal operator fatigue. These features make these tapping screws ideal for automotive trim, electronic enclosures, consumer products, and industrial equipment where reliable plastic-to-plastic or plastic-to-metal fastening is critical.

Specification Summary & Compliance

These fasteners feature a No. 6 screw size with 1/2" length and 0.138" thread diameter, manufactured to precise dimensional standards with 19 threads per inch and right-hand threading. The TRS (Thread Rolling Screw) design follows industry-standard thread forming specifications for plastic applications, with fully threaded shank and blunt tip configuration. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest restrictions on hazardous substances for global manufacturing requirements.
