This design is best suited for applications where the bolt is fully engaged in a tapped hole or when clamping force needs to be distributed across the bolt&#8217;s full length.<\/li>\n<li><strong>DIN 931 (Partially Threaded):<\/strong> Bolts manufactured to this standard feature a partially threaded shank with a smooth, unthreaded portion under the head. This unthreaded shank provides superior shear strength, making it the preferred choice for applications that must resist sideways forces and require precise alignment.<\/li>\n<\/ul>\n<h4><strong>Crucial Clarification on Material and Grade<\/strong><\/h4>\n<p>The product page contains conflicting information in its summary table. The following clarification is essential for accurate product understanding:<\/p>\n<ul>\n<li><strong>Material:<\/strong> The product is a <strong>Brass Hex Bolt<\/strong>. The listing of &#8220;Stainless Steel&#8221; alongside &#8220;Brass&#8221; is a template error. The detailed product introduction correctly identifies the material as &#8220;high-quality brass, which is an alloy mainly composed of copper and zinc.&#8221;<\/li>\n<li><strong>Grade:<\/strong> The listed property classes (4.8, 8.8, 10.9, 12.9, A2-70, A4-70, etc.) are standards for <strong>carbon steel and stainless steel<\/strong> fasteners. These grades are <strong>not applicable<\/strong> to brass bolts. Brass has its own material specifications and strength properties, which are different from those of steel.<\/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>Hex Bolt<\/td>\n<\/tr>\n<tr>\n<td><strong>Standards<\/strong><\/td>\n<td>DIN 931 (Partially Threaded), DIN 933 (Fully Threaded)<\/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>Brass (Copper-Zinc Alloy)<\/td>\n<\/tr>\n<tr>\n<td><strong>Grade<\/strong><\/td>\n<td>Not Applicable (Steel grades do not apply)<\/td>\n<\/tr>\n<tr>\n<td><strong>Surface \/ Finish<\/strong><\/td>\n<td>Plain, Polished (Natural golden appearance)<\/td>\n<\/tr>\n<tr>\n<td><strong>Size Range<\/strong><\/td>\n<td>M4 to M20 (with various lengths available)<\/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>Electrical Equipment, Plumbing, Decorative Hardware, Light-Duty Mechanical<\/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<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h4><strong>Key Features<\/strong><\/h4>\n<ul>\n<li><strong>Good Electrical Conductivity:<\/strong> Brass is an excellent conductor of electricity, making these bolts ideal for fastening electrical components, terminals, and busbars.<\/li>\n<li><strong>Excellent Corrosion Resistance:<\/strong> The copper content in brass provides natural resistance to corrosion and rust, making it suitable for plumbing and certain marine environments.<\/li>\n<li><strong>Aesthetic Appeal:<\/strong> The natural golden color of polished brass adds a high-end, decorative touch to projects, making it popular for furniture, fixtures, and architectural hardware.<\/li>\n<li><strong>Non-Marring Material:<\/strong> Brass is softer than steel, which reduces the risk of scratching or damaging the surfaces of the components being fastened.<\/li>\n<li><strong>Non-Sparking:<\/strong> Brass is a non-sparking metal, a critical safety feature for applications in explosive or flammable environments.<\/li>\n<\/ul>\n<h4><strong>Common Applications<\/strong><\/h4>\n<ul>\n<li><strong>Electrical Equipment:<\/strong> Connecting components in electrical cabinets, switchgear, and grounding applications.<\/li>\n<li><strong>Plumbing Systems:<\/strong> Fastening pipes, valves, and fittings where water corrosion is a concern.<\/li>\n<li><strong>Decorative Hardware:<\/strong> Used in high-end furniture, lighting fixtures, and architectural details where appearance is important.<\/li>\n<li><strong>Musical Instruments:<\/strong> Commonly used in the assembly of brass and woodwind instruments.<\/li>\n<li><strong>Light-Duty Mechanical:<\/strong> Suitable for applications where high tensile strength is not the primary requirement but corrosion resistance and appearance are.<\/li>\n<\/ul>\n<h4><strong>Installation Guidelines<\/strong><\/h4>\n<ol>\n<li>Ensure the hole is correctly sized for the bolt.
