Professional Applications & Engineering Value

These No. 0 x 1/4" zinc-plated steel tapping screws are specifically engineered for challenging plastic fastening applications where material integrity is critical. The TRS thread forming technology eliminates the need for pre-tapped holes while creating strong, permanent threads that resist vibration-induced loosening. The T5 Torx Plus drive system delivers maximum torque transfer without stripping, making these screws ideal for high-volume assembly operations in electronics enclosures, automotive plastic components, and consumer products. The tri-lobe shank design and precise 42 threads per inch configuration ensure superior holding power in thermoplastics and other plastic materials, preventing pull-out failures while maintaining material structural integrity.

Specification Summary & Compliance

These thread forming screws for plastic feature a No. 0 thread diameter with 42 threads per inch, 1/4" length, and standard Class 2A thread tolerances. The zinc-plated steel construction provides corrosion protection while maintaining mechanical strength. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial applications. The TRS thread forming design follows industry standards for plastic fastening applications, delivering reliable performance in various plastic materials with recommended No. 54 drill bit preparation.
