Questions about this product
- What bolt sizes do these washers fit?
- They come in metric inner diameters of M4.2, M4.8, M5.5, M6.3, M8, and M10. Each washer is about 2.5 mm thick. Pick the inner diameter that matches your screw or bolt shank.
- What are these sealing washers made of?
- The core is 304 stainless steel for corrosion resistance, with a bonded EPDM rubber face for sealing. The rubber handles -40°C to +120°C and resists water, steam, and mild acids. A serrated design keeps them from backing out.
- Where do bonded EPDM washers work best?
- Use them anywhere you need a waterproof, dustproof seal around a fastener. They're common on outdoor junction boxes, electrical enclosures, and marine fittings. The non-slip serration also resists loosening from vibration.
