Square Nuts

Square Nuts

Square Nuts are four sided square body nut fasteners with centre tapping. Square nuts are often used with square headed bolts. However its use is not limited to only square headed bolts. Square body profile is can sustain less torquing force as compared to 6 sided hexagon. Square nuts are also known by 4 sided nuts and square body nuts. Square 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.
