These fasteners are intended for creating detachable connections that do not require significant tightening force and are designed for frequent manual fastening without the use of locksmith tools.<\/p>\n<p>General technical regulations for this group of fasteners are defined in the first part of the DIN 267 standard, and acceptance test protocols and quality control comply with the requirements of DIN 267 (part 5). Structurally, wing nuts are equipped with flat protruding elements (&#8220;wings&#8221;), which provide optimal torque when tightened by hand.<\/p>\n<h3>Thread parameters and materials<\/h3>\n<p>The nominal thread diameter for DIN 315 products ranges from M4 to M24. The thread pitch is regulated by the provisions of DIN 13 (part 13) and ranges from 1 to 52 mm. Thread accuracy tolerances according to DIN ISO 4759 (part 1) correspond to classes 6H (accuracy B) and 7H (accuracy C).<\/p>\n<p>EV Group China supplies wing nuts made from various materials, including:<\/p>\n<ul>\n<li>Malleable cast iron;<\/li>\n<li>Carbon steels with protective galvanic coating according to DIN 267 (part 9) or other types of anti-corrosion treatment according to the customer&#8217;s specification;<\/li>\n<li>Austenitic stainless steels;<\/li>\n<li>Non-ferrous alloys.<\/li>\n<\/ul>\n<p>When choosing fasteners for critical assemblies, it is recommended to take into account operating conditions and the aggressiveness of the environment.
