The most common mistake is reusing an old lockwasher instead of installing a new one, which can let a fastener work loose over time. For sizing, always confirm against the exact part number and diagram position rather than fastener size alone, since several similar washers can look alike.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563857543204,"sku":"41471","price":3.44,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/37593ab3-d48b-4174-bfb9-e6dfe3ba7aad.png?v=1790288457","url":"https:\/\/marisolmarine.com\/products\/merc-243","provider":"Marisol Marine Company","version":"1.0","type":"link"}
