DIN 934 Hex Nut

DIN 934 Hex Nuts, with their internal machine screw threads, are the most common type of nut in use and are mated with virtually all externally threaded fasteners that have machine screw threads. Their nominal (maximum) thickness is about 0.8 times their nominal size (denoted as ~0.8d), so an M10 hex nut has a thickness of 8 mm. Class 6, 8 and 10 steel, and Class 50 (uncommon sizes), Class 70 (A2-70, A4-70), Class 80 (A4-80) stainless steel hex nuts are available. A2 stainless steel is comparable to 18-8 and A4 is equivalent to 316. Coarse threads are standard, but some are available with fine and extra fine threads; right-hand threads are typical. Plain finish, which lacks a rust inhibiting surface treatment, and zinc plated are common finishes for steel. Thread tolerance is 6H for plain finish and plated steel and stainless steel. The strength grade (Class) of the nut should always be equal to or greater than that of the screw. DIN 934 Hex Nuts are similar to ISO 4032, Style 1; JIS B1181; and ANSI B18.2.4.1M, Style 1. If you need a thin (reduced height) nut and can tolerate reduced strength, consider DIN 439 B.
