- Environmental regulation compliance with RoHS 3 and REACH ensures safe use in sensitive applications
Professional Applications & Engineering Value
These PTFE plastic screws with 2-56 UNC coarse threading deliver critical performance advantages in challenging industrial environments. The white PTFE material provides excellent chemical resistance, making these rounded head screws ideal for chemical processing, food equipment, and laboratory applications where contamination must be avoided. The slotted drive pan head design ensures easy installation while the fully threaded configuration maximizes engagement in soft materials or thin sections. With operating capabilities from cryogenic conditions to high-temperature environments, these temperature resistant screws solve thermal expansion mismatch issues common in multi-material assemblies, preventing loosening or failure across extreme temperature cycles.
Specification Summary & Compliance
This 1/4" length plastic screw features precise Class 2A thread fit with UNC coarse thread spacing (2-56 thread size) manufactured to ASME B18.6.3 dimensional standards. The fastener is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and meets REACH (EC 1907/2006) requirements for chemical safety. Manufactured in the inch system with standard rounded head profile and right-hand thread direction for consistent performance in industrial applications.
