They are made from 316 marine-grade stainless steel, which is specifically formulated to resist the corrosive effects of saltwater. This is the standard for high-quality yacht and boat hardware.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cspan class=\"faq-question\"\u003eDo they come with mounting screws?\u003c\/span\u003e\n    \u003cp class=\"faq-answer\"\u003eNo, screws are not included with the purchase. You should select marine-grade 316 stainless steel screws to match the base. For best results, use a silicone sealant or marine caulk beneath the base to ensure a fully watertight installation against your boat's deck.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cspan class=\"faq-question\"\u003eWhat is the difference between the \"Front\/Center\" and \"Front\/Rear\" style brackets?\u003c\/span\u003e\n    \u003cp class=\"faq-answer\"\u003eThe main difference is in the base footprint. The \"Front\/Center\" (standard stanchion) has a slightly shorter, narrower base, making it suitable for tighter spaces like the bow or midship. The \"Front\/Rear\" (aft) has a wider, longer base for increased stability on the transom or stern. Always measure your available deck space before ordering.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cspan class=\"faq-question\"\u003eWill these fit a 1-inch (25.4mm) tube?\u003c\/span\u003e\n    \u003cp class=\"faq-answer\"\u003eYes, they are designed to fit standard 1-inch OD tubing perfectly. The inner diameter of the ring is 25.5mm, which provides a snug fit for 25.4mm tubing. You may need to lightly sand or file the inside of the tube if it is oversized for a smooth installation.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cspan class=\"faq-question\"\u003eWhat is silica sol casting and why is it better than standard casting?\u003c\/span\u003e\n    \u003cp class=\"faq-answer\"\u003eSilica sol investment casting is a premium manufacturing process that uses a fine ceramic mold to create parts with exceptional surface finish and dimensional accuracy. It results in a denser, smoother, and stronger final product with almost no porosity, which means better resistance to cracking and cleaner, more beautiful looks compared to sand casting.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"25mm Fore\/Aft Support Bracket","offer_id":52268846612754,"sku":"HKTBCLA440001","price":36.8,"currency_code":"USD","in_stock":true},{"title":"25mm Mid-Rail Support Bracket","offer_id":52268846645522,"sku":"HKTBCLA440002","price":36.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/O1CN01jD1aqD25h9nduYYdw__826417557.jpg?v=1778657774","url":"https:\/\/homediyer.com\/products\/marine-316-stainless-steel-boat-rail-stanchion-base-mount-1-inch-tube","provider":"HomeDIYer","version":"1.0","type":"link"}
