Professional Applications & Engineering Value
This nylon self-retaining washer is engineered to address common industrial challenges such as vibration-induced fastener failure and corrosion. The Nylon Plastic material offers inherent resistance to chemicals and moisture, while the self-retaining feature ensures the washer stays in place during assembly, speeding up production lines. With a temperature range of -40°F to 180°F, it performs reliably in applications from automotive assemblies to outdoor machinery, where thermal fluctuations are frequent. Its precise 0.69" ID for 1/2" screw size and 1.125" OD provide a snug fit, reducing the risk of installation errors and improving overall structural integrity in industrial washers and fastener systems.
Specification Summary & Compliance
This washer adheres to inch system measurements with an internal diameter of 0.69", outer diameter of 1.125", and thickness ranging from 0.022" to 0.042". It is manufactured to ensure dimensional accuracy for reliable performance with 1/2" screws. The product is fully RoHS 3 (2015/863/EU) Compliant, meeting stringent environmental and safety standards for hazardous substance restrictions, making it suitable for use in regulated industries and international supply chains.
