This specification defines the requirements for high-strength socket button head (SBHCS) and socket flat countersunk head (SFHCS) screws. The products are manufactured from alloy steels that have undergone quenching and tempering processes to achieve optimal mechanical properties. The thread diameter range for button head products covers values from 0.060 to 0.625 inches, and for flat countersunk head products from 0.060 to 1.5 inches.<\/p>\n
The fasteners regulated by this standard are designed to withstand significant shear loads. The ultimate tensile strength ranges from 122 to 150 ksi, making them indispensable in critical mechanical engineering assemblies where high load-bearing capacity is required.<\/p>\n
The metric version of the ASTM F835M standard establishes parameters for screws with a nominal thread diameter from M3 to M20. The mechanical properties of the materials strictly correspond to strength class 12.9 according to the requirements of ISO 898\/1, which guarantees performance stability under heavy-duty operating conditions.<\/p>\n
Screws manufactured according to the F835 standard are optimized for resistance to shear stresses while providing strength characteristics equivalent to class 10.9 per the international ISO 898-1 standard. EV Group China supplies only certified products that meet the most stringent industry quality standards.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[112],"class_list":["post-69808","wiki","type-wiki","status-publish","hentry","wiki_category-astm"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69808","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\/69808\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69808"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69808"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
