This is a standard electro-plating process that deposits a thin layer of zinc, providing a bright, clear or bluish finish and good corrosion resistance for indoor or mild outdoor conditions. It is less robust than the Hot-Dip Galvanized (HDG) option.<\/li>\n<li><strong>Material (Carbon Steel):<\/strong> The &#8220;Material&#8221; field lists both &#8220;Carbon Steel&#8221; and &#8220;Stainless Steel&#8221;. This specific product, being zinc-plated, is made from <strong>Carbon Steel<\/strong>. Stainless steel is inherently corrosion-resistant and does not require zinc plating.<\/li>\n<li><strong>Grade Inconsistency:<\/strong> The &#8220;Grade&#8221; field lists both carbon steel property classes (4.8, 8.8, 10.9, 12.9) and stainless steel grades (A2-70, A4-80). As this is a Carbon Steel product, only the <strong>carbon steel property classes are applicable<\/strong>.<\/li>\n<li><strong>Lifting Safety:<\/strong> The term &#8220;Live Bolt&#8221; and its use in machinery implies it can handle loads. However, the DIN 444 standard is dimensional, not a lifting performance standard. The actual <strong>Working Load Limit (WLL)<\/strong> depends on the material grade, size, and application. This must be confirmed with the manufacturer before using the bolt for any critical load-bearing or overhead lifting scenarios.<\/li>\n<\/ul>\n<h4><strong>Product Parameters (Corrected and Clarified)<\/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>Zinc Plated DIN 444 Eye Bolt \/ Live Bolt<\/td>\n<\/tr>\n<tr>\n<td><strong>Standard<\/strong><\/td>\n<td>DIN 444<\/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><strong>Carbon Steel<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>Grades<\/strong><\/td>\n<td><strong>4.8 (Standard), 8.8, 10.9, 12.9 (High-Strength)<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>Finish<\/strong><\/td>\n<td><strong>White Zinc Plated<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>Size Range<\/strong><\/td>\n<td>M4 to M24 (and larger, up to M36 as per the dimensional table)<\/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>Agriculture, General Industry, Jigs &amp; Fixtures, Construction<\/td>\n<\/tr>\n<tr>\n<td><strong>\u26a0\ufe0f Safety Note<\/strong><\/td>\n<td><strong>Working Load Limit (WLL) must be confirmed before use in load-bearing applications.<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h4><strong>Key Features<\/strong><\/h4>\n<ul>\n<li><strong>Good Corrosion Resistance:<\/strong> The white zinc plating provides a protective barrier against moisture and rust, suitable for mild environments.<\/li>\n<li><strong>Cost-Effective Solution:<\/strong> Carbon steel with zinc plating is an economical choice for projects where the extreme corrosion resistance of stainless steel or HDG is not required.<\/li>\n<li><strong>Flexible Connection Point:<\/strong> The &#8220;Live Bolt&#8221; design with its elongated eye is ideal for creating pivoting joints when used with a pin, clevis, or rod.<\/li>\n<li><strong>Standardized Dimensions:<\/strong> Adherence to the DIN 444 standard ensures consistent sizing for reliable fitment in machinery and fixtures.<\/li>\n<li><strong>Wide Range of Strengths:<\/strong> Available in standard (4.8) and high-tensile (8.8, 10.9, 12.9) grades to match various load requirements.<\/li>\n<\/ul>\n<h4><strong>Typical Applications<\/strong><\/h4>\n<ul>\n<li><strong>Agricultural Machinery:<\/strong> Used for linkages on tractors and other farm equipment that require a pivoting and adjustable connection.<\/li>\n<li><strong>Jigs and Fixtures:<\/strong> Serves as a clamping bolt or pivot pin in manufacturing and assembly setups.<\/li>\n<li><strong>General Construction:<\/strong> Used for bracing and creating non-critical connection points.<\/li>\n<li><strong>Industrial Equipment:<\/strong> Incorporated into machinery as an adjustable fastener or guide.<\/li>\n<li><strong>DIY Projects:<\/strong> Useful for creating custom gates, hinges, or tie-down points.<\/li>\n<\/ul>\n<h4><strong>Installation and Safe Use Guidelines<\/strong><\/h4>\n<ol>\n<li><strong>Select the Correct Bolt:<\/strong> Choose the appropriate size and grade for your intended load. <strong>Always verify the bolt&#8217;s rated load capacity (WLL) before use.<\/strong><\/li>\n<li><strong>Prepare for Installation:<\/strong> Align the holes in the components you wish to connect.<\/li>\n<li><strong>Secure the Bolt:<\/strong> Insert the bolt through the holes and secure it firmly with a matching nut.<\/li>\n<li><strong>Make the Connection:<\/strong> Insert a pin, rod, or cable through the eye to connect the other parts and create the flexible joint.<\/li>\n<li><strong>Perform Regular Checks:<\/strong> Periodically inspect the bolt, threads, and eye for any signs of wear, corrosion, or damage, especially when used outdoors or under dynamic loads.
