Machine Bolts

Machine Bolts are regular hex head or square head bolts with externally threaded body, used with a nut or tapped hole. Machine bolts comes in variety of other head styles. Hex head and square head gives effective wrenching capabilities for bolting. Machine bolts are used with hex nuts or a tapped hole. Machine bolt 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.
