12 Point Flange Nuts are special design nuts with body equally divided into 12 flats. This 12 point design allows more torque to be applied to the joint. 12 point nuts are used with 12 point flange bolt or screws. 12 point flange nuts are also referred as 12 point nuts. 12 point flange 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 12 point nuts are manufactured in high tensile material grades but can be produced across all material categories and astm specifications.
