To ensure operational reliability under higher loads (strength classes 10 and 12), it is necessary to use type 2 nuts according to the DIN 971-2 standard, as they feature an increased profile height.<\/p>\n<p>This specification covers the technical parameters of hexagon nuts type 1 with metric fine thread. The nominal diameter range of the products varies from 8 to 39 mm. Product classification is determined based on dimensional characteristics: grade A for diameters up to 16 mm and grade B for products with a diameter exceeding 16 mm. Standard strength classes are 6 and 8, according to the DIN 267-23 regulation.<\/p>\n<p>For projects requiring specific characteristics beyond the scope of this regulatory document, EV Group China specialists are ready to provide alternative engineering solutions.<\/p>\n<h3>Technical delivery conditions<\/h3>\n<table class=\"table table-bordered table-hover\">\n<tbody>\n<tr>\n<td>Manufacturing material<\/td>\n<td>Steel<\/td>\n<\/tr>\n<tr>\n<td>General requirements<\/td>\n<td>DIN 267-1<\/td>\n<\/tr>\n<tr>\n<td>Thread<\/td>\n<td>6H (according to DIN 13 parts 12, 15)<\/td>\n<\/tr>\n<tr>\n<td>Mechanical properties: strength class<\/td>\n<td>6, 8 (according to DIN 267-23)<\/td>\n<\/tr>\n<tr>\n<td>Product grade<\/td>\n<td>d\u226416mm: A; d>16mm: B (according to DIN ISO 4759-1)<\/td>\n<\/tr>\n<tr>\n<td>Surface quality<\/td>\n<td>Tolerances per DIN 267-2; proof load testing per DIN 267-21; surface defects per DIN 267-9; hot-dip galvanizing per DIN 267-10<\/td>\n<\/tr>\n<tr>\n<td>Acceptance testing<\/td>\n<td>According to DIN 267 part 5<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[116,122],"class_list":["post-66943","wiki","type-wiki","status-publish","hentry","wiki_category-din","wiki_category-standarty"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/66943","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\/66943\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=66943"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=66943"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
