This Standard is included in DIN Handbook 364. Covers UNC, UNF & UNEF (coarse, fine and extra fine thread series), and standard constant pitch series for an adjusted system of diameter/pitch combinations. Covers essential and design forms, and sets out, in table form, primary measurements, limits and tolerances for all diameter/pitch combinations in those 4 series. Sets out bases of tolerance for Unified screw threads; sets out 5 sizes with diameter less than 1/4 in for attachment and general applications. Arises from negotiations involving UK, USA and Canada. Conforms with relevant sections of US standard ASA B1.1 - 1960.
