- Compliance with major industry and environmental standards guarantees quality, safety, and regulatory acceptance
Professional Applications & Engineering Value
Engineered for demanding industrial settings, these clear polycarbonate flat head screws solve critical challenges where metal fasteners fail. The polycarbonate plastic material inherently resists corrosion, galvanic reactions, and many chemicals, making these slotted screws perfect for electronics, food processing equipment, marine hardware, and medical devices. The 3/8"-16 UNC coarse thread ensures rapid installation and high pull-out strength in plastics and soft materials, while the flat head with 82° countersink creates a smooth, finished surface that enhances safety and airflow. Their temperature resistance from sub-zero to elevated heat conditions ensures long-term reliability without degradation, providing a durable, non-conductive, and visually transparent industrial plastic fastener solution.
Specification Summary & Compliance
This screw features a Class 2A thread fit per UNC standards, ensuring consistent dimensional accuracy and interchangeability. Manufacturing and dimensional specifications conform to ASME B18.6.3. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant (as of 01/17/2023 for SVHC 233), confirming adherence to strict environmental and safety regulations for hazardous substances.
