Skrutky s polguľovou hlavou a vnútorným šesťhranom so zníženou únosnosťou, z ocele a koróziivzdornej ocele, s metrickým hrubým závitom, trieda výrobku A; nízka klenutá hlava nemá nákružok, na rozdiel od ISO 7380-2. Skrutka sa uťahuje šesťhranným kľúčom usadeným v otvore zapustenom do nízkej klenutej hlavy a hlava leží na povrchu súčiastky, namiesto aby sa do nej zapúšťala: súčiastka nepotrebuje valcové ani kužeľové zahĺbenie a zaoblený vršok neponúka hranu, o ktorú by sa zachytila ruka alebo kábel; tak sa upevňujú veká, ochranné kryty, panely a držiaky príliš tenké na zahĺbenie. Veľkosť je dvojica d × l: priemer závitu určuje priemer hlavy dk, výšku hlavy k, veľkosť šesťhranu s a hĺbku kľúča t, zatiaľ čo dĺžka rozhoduje, či si skrutka ponechá hladkú časť, alebo je opatrená závitom až k hlave, a s tým aj o polomere pod hlavou, ktorý je pri skrutke so závitom až k hlave väčší. Hlava je širšia a zhruba o polovicu nižšia ako hlava skrutky s valcovou hlavou rovnakého závitu - pri M6 má priemer 10,5 mm a výšku 3,3 mm a kľúč 4 mm namiesto 5 mm - a práve otvor zapustený do takej nízkej hlavy obmedzuje zaťaženie, ktoré skrutka znesie: minimálna pevnosť pri pretrhnutí danej veľkosti je 80 % pevnosti plne únosnej skrutky rovnakého závitu a rovnakej pevnostnej triedy, čo značenie ukazuje nulou pred pevnostnou triedou, napríklad 010.9. Vzťažná dĺžka závitu b je do M12 2d + 12 mm a pri M16 3d; v roku 2022 bola zvýšená, aby aj čiastočne zavitovanú skrutku M16 bolo možné skúšať ťahom. Zahŕňa závity M3 až M16 s menovitými dĺžkami 6 až 90 mm. Vyhotovením s nákružkom pod hlavou je ISO 7380-2.
