The three socket-drive families are often confused: DIN 912 \/ ISO 4762 cylindrical head cap screws, ISO 7380 button head screws, and DIN 7991 \/ ISO 10642 countersunk screws. In China the same parts are made to GB\/T 70.1, GB\/T 70.2 and GB\/T 70.3.\n\nMetric coarse thread is standard from M1.6 to M20. Stock materials are 304 (A2-70) and 316 (A4-70) stainless steel, 12.9 and 10.9 alloy steel, plus nylon (PA66) and TC4 titanium for light-duty and non-magnetic applications. Length is measured <strong>under the head<\/strong> on DIN 912 but <strong>overall<\/strong> on DIN 7991 \u2014 check that before you specify a replacement.\n\nFor a general-purpose part, start with the <a href=\"https:\/\/sfxtec.com\/de\/product-category\/screws\/socket-head-screws\/din912\/\">DIN 912 socket head cap screws<\/a>. For dimensions, thread length rules, counterbore data and grade selection, read the <a href=\"https:\/\/sfxtec.com\/de\/din-912-socket-head-cap-screws\/\">DIN 912 sizing and grade guide<\/a>. Single pieces are orderable \u2014 there is no minimum order quantity, and freight is quoted separately so you see the real landed cost.\n\nComparing head styles? <a href=\"https:\/\/sfxtec.com\/de\/din-912-vs-iso-7380-vs-din-7991\/\">DIN 912 vs ISO 7380 vs DIN 7991<\/a> puts head height, hex key size and the countersunk length rule side by side.","link":"https:\/\/sfxtec.com\/de\/product-category\/screws\/socket-head-screws\/","name":"Zylinderschrauben","slug":"socket-head-screws","taxonomy":"product_cat","parent":28,"meta":[],"menu_order":0,"_links":{"self":[{"href":"https:\/\/sfxtec.com\/de\/wp-json\/wp\/v2\/product_cat\/129","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sfxtec.com\/de\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/sfxtec.com\/de\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/sfxtec.com\/de\/wp-json\/wp\/v2\/product_cat\/28"}],"wp:post_type":[{"href":"https:\/\/sfxtec.com\/de\/wp-json\/wp\/v2\/product?product_cat=129"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
