It consists of a smooth, rounded dome head with no drive recess, providing a safe, snag-free surface. Directly beneath the head is an integral <strong>square neck<\/strong>. When the bolt is installed into a square hole in metal or driven into a round hole in wood, this neck embeds itself, effectively locking the bolt in place and preventing it from turning as the nut is tightened. This allows for convenient one-sided assembly with a single wrench.<\/li>\n<li><strong>Carbon Steel Material:<\/strong> These bolts are crafted from high-quality carbon steel and are available in a wide range of property classes, including <strong>4.8, 8.8, 10.9, and 12.9<\/strong>. This selection allows you to choose the appropriate tensile strength for your project, from general-purpose light-duty applications (Grade 4.8) to high-stress structural connections (Grade 8.8 and higher).<\/li>\n<li><strong>Black Oxide Coating:<\/strong> The bolts are treated with a black oxide conversion coating. This process creates a chemically altered surface layer that provides a visually appealing matte black finish. It offers mild corrosion and wear resistance, making it suitable for indoor or dry environments. For enhanced protection, the coating readily accepts rust-preventative oils.<\/li>\n<\/ul>\n<h4><strong>Product Parameters<\/strong><\/h4>\n<p>The technical specifications for our Black Oxide Coated DIN 603 Carriage Bolts are provided below for your procurement and engineering needs.<\/p>\n<div class=\"MarkdownTable_tableContainer__2k5Kh\" tabindex=\"0\" role=\"region\">\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Specification<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Product Name<\/strong><\/td>\n<td>Black Oxide Carriage Bolt DIN 603<\/td>\n<\/tr>\n<tr>\n<td><strong>Standard<\/strong><\/td>\n<td>DIN 603<\/td>\n<\/tr>\n<tr>\n<td><strong>Material<\/strong><\/td>\n<td>Carbon Steel<\/td>\n<\/tr>\n<tr>\n<td><strong>Property Class \/ Grade<\/strong><\/td>\n<td>4.8, 8.8, 10.9, 12.9<\/td>\n<\/tr>\n<tr>\n<td><strong>Surface Treatment<\/strong><\/td>\n<td>Black Oxide Coating<\/td>\n<\/tr>\n<tr>\n<td><strong>Head Style<\/strong><\/td>\n<td>Round Dome Head with Square Neck<\/td>\n<\/tr>\n<tr>\n<td><strong>Diameter Range<\/strong><\/td>\n<td>M3 &#8211; M16<\/td>\n<\/tr>\n<tr>\n<td><strong>Measurement System<\/strong><\/td>\n<td>Metric<\/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>Key Feature<\/strong><\/td>\n<td>Self-locking square neck for anti-rotation, aesthetic black finish<\/td>\n<\/tr>\n<tr>\n<td><strong>Application<\/strong><\/td>\n<td>Woodworking, Fencing, Furniture, General Industry<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h4><strong>Product Features<\/strong><\/h4>\n<p>These bolts are engineered with several key features to deliver security, convenience, and a professional finish:<\/p>\n<ul>\n<li><strong>Self-Locking Anti-Rotation Neck:<\/strong> The square neck securely locks into the workpiece, allowing for easy tightening of the nut without needing to hold the bolt head.<\/li>\n<li><strong>Smooth, Safe Head Design:<\/strong> The low-profile dome head provides a clean, finished appearance and is free of sharp edges, making it ideal for applications in public areas or on furniture.<\/li>\n<li><strong>Simple Security:<\/strong> Because the head cannot be turned with common tools, it offers a degree of tamper resistance for securing gates, shed doors, and other fixtures.<\/li>\n<li><strong>Aesthetic Matte Black Finish:<\/strong> The black oxide coating provides a visually appealing, non-reflective finish that is perfect for decorative hardware, restoration projects, or when a dark fastener is required.<\/li>\n<li><strong>Versatile Strength Options:<\/strong> Available in multiple strength grades to match the load requirements of everything from garden benches to heavy timber construction.<\/li>\n<li><strong>DIN 603 Standard Compliance:<\/strong> Manufactured to precise international standards, guaranteeing dimensional accuracy, consistent quality, and reliable performance.<\/li>\n<\/ul>\n<h4><strong>Product Applications<\/strong><\/h4>\n<p>The unique design of the carriage bolt makes it exceptionally well-suited for a variety of applications, especially in woodworking and construction:<\/p>\n<ul>\n<li><strong>Woodworking &amp; Timber Construction:<\/strong> The primary application for carriage bolts.
