Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in various industrial environments.
- Enhanced holding power in plastic materials due to the tri-lobe shank design, which prevents loosening under vibration and stress.
- Efficient thread forming technology creates strong, permanent threads in plastic without pre-tapping, reducing installation time and tooling costs.
- Easy installation and removal with an external hex drive, allowing for quick fastening using standard 3/16" drill bits and wrenches.
- Full threading for maximum grip along the entire 1/2" length, providing consistent clamping force and stability in plastic assemblies.
- Blunt tip design minimizes material damage during insertion, preserving the integrity of plastic components and reducing waste.
- Compliance with RoHS 3 and REACH regulations ensures safe, environmentally responsible use in global industrial applications.
Professional Applications & Engineering Value
These No. 12 TRS tapping screws are engineered to address common challenges in plastic fastening, such as strip-out and weak thread retention. The zinc-plated steel material offers excellent durability against moisture and chemicals, while the thread forming action and tri-lobe shank create high-displacement threads that resist back-out in thermoplastics and other polymers. Ideal for industrial assembly, electronics enclosures, and automotive plastic components, these screws provide reliable, vibration-resistant connections without the need for additional inserts, streamlining production and reducing lifecycle costs.
Specification Summary & Compliance
This product features a No. 12 screw size with a 1/2" length, fully threaded right-hand design, and external hex drive for standard tool compatibility. Manufactured to precise dimensions, including a 0.216" thread diameter and 11 threads per inch, it ensures consistent performance in plastic applications with a recommended 3/16" drill bit. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, these screws meet stringent environmental and safety requirements for industrial use.
