Imperial Hex Nuts

Hex nuts are six sided nuts used with bolts, set screws and threaded rod. Imperial sizes are needed when repairing or matching machinery built to inch threads. Check the thread form as well as the diameter, because UNC, UNF, BSW and BSF do not interchange.

Our range runs from #4 number sizes up to 2 1/2", plus BA sizes from 8BA to 0BA. Threads include UNC, UNF, UNEF, UNS, BSW, BSF, BSP and BA. Materials include high tensile and 2H steel, mild steel, A2 and A4 stainless and brass, in bare, zinc plated, yellow zinc and hot dip galvanised finishes.

For metric sizes, see Hex Nuts. For a self locking nut, see Imperial Nyloc Nuts.
