Déanfaidh na cúpláin DIN 3852 fireann A & B comhcheangal le cúpláil an DIN baineann.
Tá snáitheanna díreacha ag an bhfoirm A & B atá ag fir agus ag mná. Tagraíonn Bileog 1 do shnáitheanna díreacha méadracha, agus tagraíonn bileog 2 do snáitheanna díreach Whitworth. Tarlaíonn an séala nuair a dhéanann an séala fáinne (Cineál A) nó an séala aghaidh (Cineál B) le héadan an chalafoirt baineann.
Is iad seo dhá shraith de chrutháin A & B DIN 3852, an solas (L) agus an tsraith throm (S).
