Square Thin Nuts

Square Thin Nuts

Square Thin Nuts are low profile square nuts with thickness half of the standard square nuts. Alike hex thin nuts, square thin nuts are coupled with square nut where it is jammed to create a lock, holding the two in place. Square thin 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.
