Its function relies entirely on having an empty space behind the wall panel for the &#8220;toggle&#8221; (the spring-loaded wings) to open and brace against the back of the material.<\/li>\n<li><strong>Conflicting Specifications:<\/strong> The product page lists an exceptionally wide size range of <strong>M6-M20<\/strong> and applications in &#8220;Heavy Industry.&#8221; This requires clarification:\n<ul>\n<li><strong>Standard Use (Light to Medium Duty):<\/strong> The smaller sizes in this range (e.g., M6, M8) are perfectly suited for their primary purpose in residential and commercial construction: hanging shelves, mirrors, light fixtures, and TV mounts on drywall.<\/li>\n<li><strong>Heavy-Duty Use (Industrial):<\/strong> The larger sizes (e.g., M10 up to M20) are extremely robust and are not intended for standard drywall, as they would require a very large hole and would likely damage the board. These heavy-duty toggle bolts are designed for more substantial hollow materials, such as <strong>hollow concrete block (CMU)<\/strong>, structural clay tile, or for securing industrial equipment and fixtures through metal panels with a service cavity behind them. This explains the &#8220;Heavy Industry&#8221; application.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h4><strong>Product Mechanism and Installation<\/strong><\/h4>\n<p>The anchor&#8217;s strength comes from its ability to create a large bearing surface behind the wall.<\/p>\n<ul>\n<li><strong>Mechanism:<\/strong> The anchor consists of two parts: a machine screw (or bolt) and the spring-loaded toggle wings. The wings are threaded like a nut and can be folded flat against the screw.<\/li>\n<li><strong>Installation Process:<\/strong>\n<ol>\n<li>Select the appropriate size toggle bolt for your load requirement and wall type.<\/li>\n<li>Drill a hole in the wall. The hole must be large enough for the folded toggle wings to pass through.<\/li>\n<li>Unscrew the toggle wings from the bolt. Pass the bolt through the hole in the item you wish to hang (e.g., the bracket for a shelf).<\/li>\n<li>Screw the toggle wings back onto the end of the bolt by just a few turns.<\/li>\n<li>Fold the wings flat so they are parallel with the bolt.<\/li>\n<li>Push the folded wings and the end of the bolt through the drilled hole in the wall. You will hear or feel the wings spring open inside the wall cavity.<\/li>\n<li>Pull back gently on the bolt to ensure the wings are braced flat against the inside surface of the wall.<\/li>\n<li>While keeping tension on the bolt, tighten it with a screwdriver until your fixture is held firmly against the wall. Do not overtighten, especially in drywall.<\/li>\n<\/ol>\n<\/li>\n<\/ul>\n<h4><strong>Product Parameters<\/strong><\/h4>\n<div class=\"MarkdownTable_tableContainer__2k5Kh\" tabindex=\"0\" role=\"region\">\n<table>\n<thead>\n<tr>\n<th>Parameter Item<\/th>\n<th>Specification Description<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Product Name<\/strong><\/td>\n<td>Spring Toggle Fixing<\/td>\n<\/tr>\n<tr>\n<td><strong>Brand Name<\/strong><\/td>\n<td>Duojia<\/td>\n<\/tr>\n<tr>\n<td><strong>Place of Origin<\/strong><\/td>\n<td>Hebei, China<\/td>\n<\/tr>\n<tr>\n<td><strong>Material<\/strong><\/td>\n<td>Carbon Steel<\/td>\n<\/tr>\n<tr>\n<td><strong>Surface Treatment<\/strong><\/td>\n<td>White Zinc Plated (WZP)<\/td>\n<\/tr>\n<tr>\n<td><strong>Available Sizes<\/strong><\/td>\n<td>M6-M20<\/td>\n<\/tr>\n<tr>\n<td><strong>Strength Grades<\/strong><\/td>\n<td>4.8, 8.8, 10.9, 12.9, etc.<\/td>\n<\/tr>\n<tr>\n<td><strong>Measurement System<\/strong><\/td>\n<td>Metric<\/td>\n<\/tr>\n<tr>\n<td><strong>Application<\/strong><\/td>\n<td>General Industry, Heavy Industry, Hollow Wall Fastening<\/td>\n<\/tr>\n<tr>\n<td><strong>Certifications<\/strong><\/td>\n<td>ISO9001, ISO14001, ISO45001, SGS<\/td>\n<\/tr>\n<tr>\n<td><strong>Packaging Options<\/strong><\/td>\n<td>Small Pack + Carton + Pallet; Bag\/Box with Pallet; Variety Packs<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h4><strong>Key Features<\/strong><\/h4>\n<ul>\n<li><strong>Excellent for Hollow Walls:<\/strong> The definitive solution for providing a strong anchor point in drywall, plasterboard, hollow block, and other cavity walls.<\/li>\n<li><strong>Spreads Load Over a Wide Area:<\/strong> The toggle wings distribute the weight across a large surface area on the back of the wall, preventing pull-through and allowing for higher load capacities than other drywall anchor types.<\/li>\n<li><strong>Easy to Use:<\/strong> The installation process is straightforward and intuitive, making it suitable for both professionals and DIY enthusiasts.<\/li>\n<li><strong>Removable Bolt:<\/strong> The fixture can be removed by unscrewing the bolt.

It is the go-to solution for creating a secure mounting point in surfaces like plasterboard (drywall), hollow-core doors, and ceilings. Made from carbon steel and finished with a protective White Zinc Plating (WZP) for rust resistance, this anchor uses spring-loaded wings that expand inside the wall cavity to distribute the load over a wide area, providing a much stronger hold than anchors that simply expand within the drilled hole.<\/p>","protected":false},"featured_media":1115,"template":"","meta":[],"product_brand":[],"product_cat":[120],"product_tag":[35,92,97,118,122,129,130],"class_list":{"0":"post-619","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-custom-anchor-bolts","7":"product_tag-expansion-anchor","8":"product_tag-concrete-anchor-bolts","9":"product_tag-anchor-bolts","10":"product_tag-anchor-bolts-factory","11":"product_tag-anchor-bolts-supplier","12":"product_tag-spring-anchor","13":"product_tag-stainless-anchor-bolts","15":"first","16":"instock","17":"shipping-taxable","18":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/mj-anchor.com\/de\/wp-json\/wp\/v2\/product\/619","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mj-anchor.com\/de\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/mj-anchor.com\/de\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mj-anchor.com\/de\/wp-json\/wp\/v2\/media\/1115"}],"wp:attachment":[{"href":"https:\/\/mj-anchor.com\/de\/wp-json\/wp\/v2\/media?parent=619"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/mj-anchor.com\/de\/wp-json\/wp\/v2\/product_brand?post=619"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/mj-anchor.com\/de\/wp-json\/wp\/v2\/product_cat?post=619"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/mj-anchor.com\/de\/wp-json\/wp\/v2\/product_tag?post=619"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
