Hex Nuts are six sided hexagon nuts, used for tightening bolts and screws. Hex nuts are often found with hex headed bolts. However its use is not limited to only hex headed bolts. Hexagonal body enables easy wrenching while putting enough torque to the bolting joint. Hex nuts can be used with all kinds of bolts. Hexagon nuts, six sided nuts are other alias of hex nuts. Hex nut dimensions are defined in both metric and imperials sizes with unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN) and iso metric thread profile. These are produced across all material categories and astm specifications.
