An assortment of zinc-plated metric carriage bolts from Hillman. Carriage bolts are commonly used in wood connections due to the square neck beneath the round, smooth head which fits securely in the hole and prevents the head from turning. Parts in full assortment all feature M6-1.00 coarse screw thread, and come in various lengths measuring 16mm thru 70mm. Full assortments of #45887 contain ten (10) refills comprised of Hillman item numbers #45888 - #45897.
