This type of hardware is widely sought after in mechanical engineering, steel construction, and heavy industry due to the high reliability of the connection and the ability to use them in confined spaces.<\/p>\n<p><img decoding=\"async\" src=\"\/image\/catalog\/wiki\/flange\/din-933.png\" alt=\"Hexagon head bolt DIN 933\" title=\"Hexagon head bolt according to DIN 933\"><\/p>\n<h3>Main Characteristics and Specifications<\/h3>\n<p>EV Group China supplies DIN 933 bolts manufactured in accordance with strict requirements for precision classes A and B. The range of nominal thread diameters covers values from M1.6 to M52, allowing for the selection of an optimal solution for any engineering task.<\/p>\n<table class=\"table table-bordered table-hover\">\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Description<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Standard<\/td>\n<td>DIN 933 (ISO 4017)<\/td>\n<\/tr>\n<tr>\n<td>Execution Type<\/td>\n<td>Full thread<\/td>\n<\/tr>\n<tr>\n<td>Diameter Range<\/td>\n<td>M1.6 \u2013 M52<\/td>\n<\/tr>\n<tr>\n<td>Precision Class<\/td>\n<td>A (for diameters up to M24), B (for others)<\/td>\n<\/tr>\n<tr>\n<td>Materials<\/td>\n<td>Carbon steel, stainless steel (A2, A4), brass<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Application Areas and Advantages<\/h3>\n<p>Using DIN 933 fasteners from EV Group China guarantees the durability of connections. The main advantages of the products include:<\/p>\n<ul>\n<li>Full thread ensures maximum grip along the entire length of the shank, which is critical for through-bolt connections.<\/li>\n<li>Strict adherence to geometric tolerances allows for the use of automated assembly lines.<\/li>\n<li>High corrosion resistance when choosing appropriate steel grades (e.g., acid-resistant alloys for the chemical industry).<\/li>\n<\/ul>\n<p>The engineering department of EV Group China recommends checking the compliance of the bolt strength class with design loads. Products with strength classes 5.6, 8.8, 10.9, and 12.9 are available in stock.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[116,122],"class_list":["post-66989","wiki","type-wiki","status-publish","hentry","wiki_category-din","wiki_category-standarty"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/66989","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki"}],"about":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/types\/wiki"}],"version-history":[{"count":0,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/66989\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=66989"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=66989"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
