Hex nuts are the most-stocked item in our Umm Al Quwain warehouse — DIN 934 / ISO 4032 from M3 to M125 and imperial to 4", in class 6, 8, 10 and 12, stainless A2 / A4, black, zinc plated and hot-dip galvanized (tapped oversize). Heavy hex, thin, fine-thread and left-hand nuts are stocked alongside.
A hex nut is a six-sided nut that mates with a bolt or stud to make the joint. Property class must match the bolt (class 8 with 8.8, class 10 with 10.9, class 12 with 12.9) so the nut is never the weakest link. DIN 934 and ISO 4032 are the general-purpose standard nuts; ISO 4033 is the high (thicker) nut; DIN 6915 / ASTM A563 are heavy hex structural nuts. Stainless nuts follow ISO 3506-2.
