Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in various environments.
- Excellent holding power in plastic materials due to the Tri-Lobe shank design, which reduces material stress and prevents stripping.
- Reliable and efficient installation with a Phillips No. 3 drive, allowing for quick, secure fastening without specialized tools.
- Optimized thread engagement with a fully threaded 0.216" diameter and 11 threads per inch, providing strong, vibration-resistant connections.
- Reduced risk of plastic cracking through thread forming technology, which displaces material rather than cutting it for a tighter fit.
- Compliance with industrial safety standards, including RoHS 3 and REACH, ensuring safe use in regulated applications.
- Versatile for various plastic assemblies, from consumer electronics to automotive components, thanks to its blunt tip and standard pan head design.
Professional Applications & Engineering Value
This No. 12 x 1" zinc-plated steel TRS tapping screw is engineered to address common challenges in plastic fastening, such as material cracking and poor thread retention. The thread forming method and Tri-Lobe shank cross-section create strong, permanent threads in plastic substrates without generating chips, minimizing assembly failures. Ideal for plastic applications in electronics, automotive, and consumer goods, it ensures secure connections that resist loosening under vibration. The zinc-plated finish enhances corrosion resistance, while the Phillips drive simplifies installation, reducing labor time and improving production efficiency in industrial settings.
Specification Summary & Compliance
This screw features a thread diameter of 0.216" with approximately 11 threads per inch, ensuring precise fit in pre-drilled holes (recommended drill bit size No. 8, 0.199" diameter). It adheres to standard thread forming (TRS) specifications for plastic materials and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental and safety standards for industrial use.
