Professional Applications & Engineering Value

These PTFE plastic slotted pan head screws deliver critical performance advantages in demanding industrial applications where metal fasteners would fail. The PTFE material provides inherent chemical inertness and non-stick properties, making these rounded head screws ideal for chemical processing equipment, food manufacturing machinery, and semiconductor manufacturing where contamination must be avoided. The extreme temperature tolerance (-350°F to 500°F) ensures reliable operation in cryogenic applications and high-heat environments without degradation. The UNC coarse threading with Class 2A fit maintains secure fastening in plastic and soft materials, while the slotted drive accommodates standard tools for maintenance-friendly assemblies. These white plastic fasteners solve corrosion and thermal expansion issues that plague traditional metal screws in specialized industrial settings.

Specification Summary & Compliance

This 1/4"-20 x 3/4" plastic screw features precise Class 2A thread fit with UNC coarse threading (20 threads per inch) and full threading along the entire length. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) requirements for chemical safety, making these fully threaded screws suitable for regulated industries and environmentally conscious applications.
