Volvo Penta fasteners are specified by grade, length, and thread form for the exact assembly — a generic substitute may not provide the correct clamp load or corrosion resistance for a marine environment. Always match by part number from the Volvo Penta parts diagram for your serial-numbered drive, and replace the old screw rather than reusing one that has been seized or corroded.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563977211940,"sku":"191844","price":18.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/191844.png?v=1771699075","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-hexagon-screw-191844","provider":"Marisol Marine Company","version":"1.0","type":"link"}
